Every year or two there comes along a new bat that quickly takes the youth baseball world by storm. I call the latest of these the “Magic Bat.”
Making contact anywhere on the barrel sends the ball to the outfield, regardless of how hard you swing or which part of the bat hits the ball—or so reported my son the first time he saw this bat in action among 9- to 10-year-olds. Each month I see ever more players in travel ball and even recreation leagues with this $300 bat:
Is this the best bat for youth baseball? If you’d like to spend $300 to improve your player’s hitting, is this the best way to spend it?
Maybe. Maybe not.
To understand whether this bat is worth the money or more generally what bat makes sense for a given player, it’s a good idea to first understand the basics of hitting, what happens when a bat collides with a ball, and what effect baseball bat design has on that collision.
This comprehensive article aims to help navigate the world of high tech bats. You’ll be better informed if you read it all, starting with the facts that never change: what it takes to be a good hitter and the basic physics of what happens when a bat hits a ball.

Deficiencies of the Typical Baseball Bat Review
I spend a considerable amount of time doing research for FilterJoe articles. I read reviews and spec sheets. I test products. I visit stores. I talk to experts. I pore through scientific studies. While not every information source is good, it is usually simple to find detailed specifications for any piece of tech gear, and there almost always seem to be at least 1 or 2 good reviews, whether the topic is a monitor, an e-reader, a battery charger, or something more esoteric.
Finding factual information and decent reviews for youth baseball bats is much harder.
For many bats I can’t even determine basic specifications beyond size and weight, and weight is fuzzy due to how the bat’s weight is distributed. Worse, the weight printed on bats is usually inaccurate, sometimes understated by as much as 3 ounces!
Nearly all bat reviews I’ve read do little more than rephrase marketing bullet points and buzzwords put out by the manufacturer, assuring the reader that this year’s model is better than last year’s model.
No reviews explain in great detail what actually makes one bat better than another, how bats are tested, and whether players who switch bats achieve measurably different results. And while reviews by customers on Amazon and other online retailers are helpful for many types of items, they are usually not helpful for bats, because there are multiple interpretations for “has great pop,” which is the most common form of praise (more on this later).
Before I could consider recommending a type of bat or specific bat for youth baseball, I needed to answer some questions:
- What is the difference between a $300 bat and a $40 bat?
- Does a Little League or PONY league player achieve better results with a $300 bat than a $40 bat? If yes, how much better?
- What do all the buzzwords mean, and how much do they matter? I’m talking about BPF, MOI, the trampoline effect, composite, end loaded, balanced, etc.
- How do I even know what a given bat is made of?
It took me weeks of research to answer most of these questions to my satisfaction. Baseball vendors and resellers are light on information, but fortunately there is good information available from Alan Nathan, Daniel Russell, and other scientists who study the physics of baseball. The components of good hitting can be learned from any competent baseball coach or coaching book.
The Basics of Hitting
I break down hitting as follows:
- Mental readiness
- See the ball
- Hit the ball
You hear many coaches say “See the ball, hit the ball” to keep it simple. But mental readiness is quite often the hardest part for batters of any age. Many hitters lack confidence and have unhelpful thoughts swirling around before each pitch, perhaps fearing being hit or striking out. Others hope to draw a walk, or perhaps wait on each pitch to see if it will be a good one before getting ready to take a swing. These kinds of thoughts and approaches don’t contribute to an appropriate state of readiness.
I have literally seen a kid who was a great batter transform into a poor batter for months after taking a particularly nasty hit by a pitch. I also know a fearless batter with poor mechanics, slow swing speed, and a tendency to swing at poor pitches who is very comfortable and ready for each pitch . . . he hits the ball into play almost every at bat.
For some players, having a bat you like and believe in may boost your confidence and therefore help with readiness. But the reality is that any hitter can become appropriately ready by following a simple formula. Many major league players swear by the book, The Mental Game of Baseball, which discusses this issue and many others related to the mental side of baseball. I will try to distill the concept of readiness down into one paragraph:
Before getting ready, it is important to stay loose, relaxed, and not overly focused while the pitcher is deliberating. Look at the pitcher’s hat or a point hundreds of feet beyond the pitcher’s head. Then get ready as the pitcher starts his motion, by assuming the pitcher is going to throw a perfect pitch. The physical part of getting ready (loading the hip by shifting weight to the back foot) follows automatically when you expect to hit a perfect pitch. Focus in on the pitcher’s hand and start your swing very shortly after the ball leaves the hand. Do all this, especially the mental parts, and you will be physically ready to “see the ball, hit the ball.”
See the ball sounds simple. Just watch the ball coming out of the pitcher’s hand and determine where it’s going to go. This turns out to be hard.
If the only pitches are fastballs, then it’s a matter of judging speed and location. Judging speed can be helped by watching the pitcher as he warms up and pitches to other batters. An observant hitter will often have the timing down before receiving the first pitch. Some may prefer to take a pitch or two to get that timing. Once you have the timing down, you know precisely when to start the swing. So you start your swing, then decide to abort or continue the swing depending on whether you like the pitch.
Many a poor hitter does not start a swing early enough—they wait to start the swing until they are sure if it’s a strike or ball. This will not work against fast pitching. This is not so much a problem with “seeing” the ball as it is with readiness. You have to be ready to hit and already (barely) starting your swing to have enough time to see and hit a good pitch.
The point of “seeing” the ball is to swing only at good pitches and if the pitch is good, aim the bat so as to hit the ball squarely on the sweet spot. Those who chase bad pitches will have difficulties hitting the ball well no matter how good their bats and no matter how well they do in every other aspect of hitting.
This all may sound obvious but it’s difficult to implement in practice. It takes time for any individual player to get used to seeing the ball well from a wide variety of pitching deliveries and speeds, anywhere from weeks to years. More typically it takes about 10-20 games to see the ball well enough to reliably make contact. And then it gets even harder to see the ball when pitchers get trickier with changeups and breaking balls.
After getting ready and then “seeing” a good pitch, you hit it. Bat speed is so critical to hitting the ball well that it merits a section of its own.
Bat Speed
To reliably hit the ball, the bat has to quickly get to where the ball is. The faster you swing a bat, the later you can start your swing, and the more time you get to see the ball to determine whether and where to swing. Also, the faster the swing, the harder the ball will be hit.
Three principle variables impact bat speed and how hard the ball can be hit:
- Player strength
- Hitting mechanics
- The bat
Player strength is obvious. The bigger and stronger the kid, the faster the bat swing. When people think of “big hitters” they often think of upper body strength. But big hands, strong wrists, strong legs, and strength in the core will also help to produce a faster swing. The biggest kid on the team is usually the player who can hit the ball the hardest.
Hitting mechanics is the series of body motions required to swing a bat. Some players, especially bigger players or those who see the ball very well, get many good hits with poor hitting mechanics at younger ages because balls aren’t pitched very hard. But as players get older, it becomes increasingly difficult to hit with poor mechanics. By high school age pretty much everyone with poor mechanics is unable to hit good pitching, because bats are heavier and pitchers throw harder and trickier. When you see a kid who is not particularly big or strong frequently hitting the ball to the outfield, it is probably because he has good mechanics. When you combine larger than average size with great mechanics—you’ll see occasional home runs and frequent doubles.
Kids with good hitting mechanics for coach pitch can have their mechanics fall to pieces if they’re afraid of kid pitch. It’s pretty difficult to hit if you’re standing far from the plate, jumping away from every pitch, or watching almost every pitch go by. But this is more mental than it is physical and is a reflection of not being truly ready to hit before each pitch. Kids who have good mechanics before kid pitch will continue to have good mechanics, though that won’t be apparent until they stop being afraid of the ball.
Those who know a lot about baseball realize that in the long run, hitting mechanics matter more than how big you are or what bat you’re using.
I don’t mean to imply there is only one set of correct mechanics. There is variation depending on age, size, and body type. There is controversy among experts on many of the finer points. There are many reasonable styles of hitting, and as Ted Williams says in The Science of Hitting, “the style must fit the player, not the other way around.”
I know a travel ball coach who taught exactly the same hitting mechanics to every player. It was a good set of mechanics, and some players got much better at hitting. Others, for whom the style was not well suited, got worse.
Another interesting thing about mechanics is the basic dichotomy between a home run swing and a contact hitter’s swing. Most players these days are taught the short, level swing of a contact hitter, which makes it easier to hit faster or trickier pitching. Bigger players sometimes develop more of a home run swing which requires loading the hip more, starting the swing earlier, and an upwards slope to the swing. The risk of a home run swing is more outs from strikeouts and pop files, but the rewards are spectacular extra base hits, including the occasional home run.
I won’t get into any more detail about mechanics as it’s a very big topic that is best learned through video or, better yet, live instruction. If you’re still questioning how much mechanics matter, whether hitting lessons are worth it, and related questions such as when it makes sense to work on mechanics, then I suggest your read my hitting mechanics post.
The bat also matters. The weight and length of the bat matters as well as how that weight is distributed. The materials and craftsmanship also matter. But exactly how much does the bat matter? What about a bat matters most?
Before going into more detail on this, it’s useful to understand what happens when a bat contacts a ball.
What Happens When a Bat Hits a Baseball
When a wood bat hits a baseball, the baseball compresses about 50%, as you can see here:

The wood barely bends at the point of contact with the ball, which makes for a very inefficient collision. If the ball hits the sweet spot of a wooden bat for a line drive hit, approximately 75% of the energy of the bat/ball collision is wasted compressing the ball and generating heat. Even more is wasted if the ball doesn’t hit the sweet spot, as additional energy is expended to vibrate the bat. The fat part of the bat is called the barrel. The sweet spot is on a portion of the barrel. It is a region where collisions with a baseball cause little or no vibration, thus minimizing wasted energy.
Conservation of momentum is a physical law that describes what happens when two objects collide. In the case of a bat and a ball, the batted ball speed (BBS) of the ball after it contacts the bat will be determined by an equation relating the speed of the bat, the speed of the ball, and a coefficient q that describes how much energy is retained when this collision occurs:
BBS = q * (pitch speed) + (1 + q) * (bat speed)
When I talk about bat speed, I am always referring to the speed of the bat at the instant it collides with the ball. Bat speed may be faster than is apparent from visual observation as strong wrists combined with flexing of the front forearm can speed up the bat just before contact.
A bat is much heavier than a ball so BBS is influenced much more by swing speed than pitch speed. For a 10-year-old batter, bat q ranges from .12 to .15, so an extra 1 MPH of swing speed translates to an additional 1.12 to 1.15 MPH of batted ball speed, and therefore 5 feet of additional distance the ball will travel. For the adult batter these numbers are slightly higher due to the higher q of the bat (1.2 MPH and 6 feet).
For more detail, read what scientist Alan Nathan has to say about the bat/ball collision. Two examples illustrate the difference between adults and kids:
Adult Batted Ball Example:
- Bat: wood 34in, 31oz, q = .20
- Bat speed: 70 MPH
- Pitch speed: 85 MPH
- Computed Batted Ball Speed: 101 MPH
- Computed distance of hit launched at 33 degree angle: 394 feet at first contact with ground
This first example is from Alan Nathan’s article and can be computed precisely using his baseball trajectory spreadsheet. I believe these numbers represent a typical minor league hitter with typical bat and pitch speeds. This example and the next assume no wind, typical atmospheric conditions, and that the ball is hit squarely on the sweet spot of the bat. This value of q, 0.20, is based on many studies of wooden bats sized for adults. In ideal, fully understood conditions, the distance a ball travels can be computed (and therefore predicted) exactly.
Of course, conditions in the real world are often a little messy. A ding on the bat, a gust of wind, a moist baseball . . . these and many other factors can cause the distance to come out differently from the value calculated by a simplified model.
By far the biggest reason for variance from the batted ball model is where the ball meets the bat. The pitcher does everything possible to make it difficult for the batter to hit the ball squarely on the sweet spot. So . . . the ball is rarely hit squarely on the sweet spot of the bat. For example, a curveball may unexpectedly drop after a hitter has nearly completed the swing, hitting the bottom side of the barrel for a weak grounder instead of a blast to the fence.
11-year-old Batted Ball Example:
- Bat: aluminum 30in, 18oz, q = .12 (a low quality non-wood bat)
- Bat speed: 40 MPH
- Pitch speed: 47 MPH
- Computed Batted Ball Speed (BBS): 53 MPH
- Computed distance of hit launched at 33 degree angle: 141 feet at first contact with ground
The bat and pitch speed numbers for this second example are typical for an 11- to 12-year-old recreation league player, and are considerably above average for a 9- to 10-year-old rec league player. There has been little scientific study of youth swing speeds and there is little data on youth bats. I derived plausible values for q on my own by downloading Alan Nathan’s baseball trajectory spreadsheet and modifying it to include the above formula. I started with average swing speeds from a 1991 study, and then increased swing speed to confirm a home run I observed by a (particularly strong) 10-year-old on a field with a fence 170 feet from home plate. I also checked with baseball scientist Alan Nathan, who was kind enough to confirm my guesswork as being right in line with what he has observed.
The value of q for a 30in, 18oz youth baseball bat ranges from .12 to .15, depending on the bat. The player who hit a home run at our local field was using an expensive, end loaded Easton XL1 bat with a q I estimate at .15 and had an unusually high swing speed for a 10-year-old of approximately 45 MPH. Had he used a bat with q = .12 with the same launch angle, bat speed, and pitch speed, the ball would have been hit 166 feet instead of 180 feet and would therefore not have cleared the fence for a home run. So using a bat with higher q did matter, by 14 feet.
At the youth level, variation in swing speeds from hitter to hitter is far greater than variation in bats. I can visually see that there are a couple players on each team at the beginning of each season (usually beginners) with very slow swing speeds—perhaps 20MPH or even less. Using a q=.12 bat, the player swinging at 20 MPH who hits the ball perfectly square on the sweet spot will hit the ball only 53 feet as opposed to 141 feet for the 40 MPH hitter (the ball will always first contact the ground in the infield). Swinging a bat that slowly decreases the chances of hitting the ball perfectly or even at all, so hitting the ball 53 feet would be rare for a player with a 20 MPH swing.
For 20MPH-swinging-players swinging a much better q = .15 bat, the distance of a perfectly hit ball would be 59 feet. That’s only 6 feet further. At the youth baseball level, variation in swing speed has a far greater impact on the distance a ball is hit than variation in q. In other words:
At the youth level, most “pop” comes from the batter, not the bat.
One could reasonably argue that it’s a bit of an extreme example to choose the batter with the slowest swing on the team. What about a 10-year-old with a more average swing speed, of perhaps 30MPH? Then, with q = .12, 93 feet (shallow outfield) is the distance of a perfectly hit ball. With the much better q = .15 bat, the distance is 102 feet. We can see that the higher the bat speed, the more the bat starts to matter—but 9 feet is still a pretty small number. Only for the fastest swinging 10-year-old batters in the league will a much better bat cause batted ball distances to increase by more than 10 feet.
The astute reader will have already realized that buying a $300 bat is not going to help hit the ball much further for the majority of youth baseball players below the age of 11. Only players who are already consistently able to contact the ball with fast swings benefit significantly from a high q bat.
I keep talking about q. What is this mysterious q? The best way to think of it is collision efficiency for a given bat when it collides with a ball on the sweet spot. The higher the q, the faster the baseball will come off the sweet spot of a bat. So the natural question to ask next is what factors impact a bat’s q.
Bat Weight vs. Bat Speed
By far the most important influence on q is bat weight. Given identical bat speed, the bigger and heavier the bat, the harder the ball will be hit. For anyone who has studied basic physics, this should be obvious from the equation describing two colliding objects. Many kids intuitively understand this and therefore want to swing a heavier bat.
As every youth baseball coach knows, bat speed is not identical for a heavier bat. The most common way to ruin a good swing is to switch to a heavier bat. The heavier the bat, the slower the swing, and the earlier a player must start the swing to have a chance of hitting the ball. If the swing is really slow, the hitter’s mechanics suffer as well and it is hard to contact the ball at all.
This concept is so important, that I devoted an entire article to discussing how to tell if your kid’s bat is too heavy.
Conversely, the lighter the bat, the faster the swing, and the more a player can wait on a pitch. Waiting longer allows you to see the pitch longer and therefore aim the bat better (or decide whether to swing). There is a point of diminishing returns from going lighter because there is a finite speed limit to how fast arms can swing. If moving to a lighter bat results in very little increase in swing speed, the ball will not be hit as far and there won’t be any benefit. However, too heavy is far more often an issue than too light.
The impact of changing to a fast-swinging, light bat cannot be overstated. In my calculations above I always assume the batter hits the ball perfectly on the sweet spot. It’s very obvious that youth players rarely hit the ball squarely on the sweet spot. Most batted balls are foul balls, weak grounders, or weak popups. Switching to a lighter bat will greatly increase the chances of hitting hard line drives, hard grounders or deep fly balls.
Though studies such as Crisco et al find that lowering the weight of same-length bats does not usually result in perfectly hit balls traveling further (despite increased swing speed), such studies are trying to determine maximum possible Batted Ball Speed (BBS). For most players, switching from a too-heavy bat to a lighter bat causes the percentage of balls that are hit very well on the sweet spot to increase, which will mean a hit ball will travel further on average, even though the maximum possible distance is lower.
To illustrate with a true story: A 9-year-old player I knew was struggling at the plate, with many swings and misses. He had below-average mechanics and below-average ability to see the ball. I suggested this player borrow a lighter and smaller 27-in, 14-oz bat. In his first couple of at-bats against live pitching with this ultra-light bat, he hit a line drive and a hard grounder. He was so excited and said, “this bat really has pop!!!”
His swing was so much faster that he could more than make up for his below-average mechanics and batting eye. He could start the swing later, aim the bat better, hit the ball closer to (or on) the sweet spot, and hit it with a faster bat speed. All of this combined to instantly generate better batting results. I’m guessing his “readiness” was also helped thanks to increased confidence.
This inexpensive one-piece aluminum bat was so light that he may have lowered the q of his bat from .12 down to .10 (just guessing). But thanks to bat quickness and increased swing speed he immediately got better results by hitting the ball close to the sweet spot far more often.
In the above example, the dominating variable was the weight of the bat. Lowering weight was a quick fix for a below-average batting eye and swing mechanics. A perfectly hit ball will not travel as far with such a light bat, but he now has a much better chance to hit the ball square on the middle of the sweet spot, which is far better than missing completely or getting poor contact that glances off the top or bottom of the barrel.
This story is not unique—I have seen it play out a few times. Many coaches see this every year. Kids love to move up to bigger and heavier bats, and we coaches know how detrimental this can be without having to do any math. Some coaches check bats every few weeks to make sure nobody has started using too heavy a bat.
On occasion, you see exactly the opposite. I knew a 10-year-old player with a very slow swing speed despite having the build a of slugger, a light bat (29 in, 17oz), and coaches who tried hard to improve his mechanics. He managed to hit the ball weakly into play on most of his at bats despite his slow swing speed and unusual mechanics. I suggested he try using a much heavier bat, the heavily end loaded Anderson Techzilla (30 in, 21oz). His swing speed stayed the same. He immediately hit the ball harder in soft toss and in his second game using the bat was hitting very hard grounders and line drives to opposite field, much harder than I had ever seen him hit the ball before.
Bat size (length) also matters. A longer bat of similar construction but same weight will be more difficult to swing, and therefore the swing speed will not be as fast. This is somewhat offset by the fact that the sweet spot is further away from the batter’s hands, and therefore traveling faster to cover the longer arc than the shorter bat. If the rotational speed of two different length of bats is identical, and the ball is hit by the bat exactly 3 inches from the end of each bat, then the longer bat will have faster speed upon point of contact with the ball. Or course, most players will not be able to swing the longer bat as fast.
There are other factors besides bat size and weight. As I mentioned above, a 30 inch bat weighing 18oz can have a q that varies between .12 and .15. So what are the other factors that impact q?
Other Factors that Make a Bat Hot Besides Weight
A bat with a high q is often referred to as a “hot” bat. A bat is considered “hot” if, compared to other bats of the same size and weight, the ball seems to travel further when hit. One’s first thought is that some special high tech material causes the ball to bounce harder off the bat. This may be the case for some bats. However, it turns out there are several factors that cause people to perceive the bat as hot, and some of them have nothing to do with the material, or in some cases not even to do with increasing q, the efficiency with which the bat collides with the ball.
I already discussed the one factor that dominates all others: the weight of the bat. The heavier the bat, the more momentum there will be when it hits the ball, for a given speed. Actually, what matters even more than the weight is Moment of Inertia (MOI). You can think of MOI as perceived swing weight. For a given bat size and weight, if a bat is heavily weighted towards the barrel, it will have a high MOI and therefore be harder to swing. For the same size and weight of bat, a bat with the weight distributed more towards the handle will have a lower MOI and be perceived as lighter and easier to swing. Measuring MOI precisely requires lab equipment, though you can tell the difference between a high MOI and low MOI bat of the same size and weight with a few practice swings.
Bat makers call a low MOI bat “balanced” (weight shifted toward the handle). A higher MOI bat with the weight shifted toward the barrel is called “end loaded.” Wood bats are always end loaded because the wood barrel is solid.
Bat makers do not list the actual MOI and this information is generally not available to consumers. It is therefore possible to get a bat you think is the right weight but it turns out to be too heavy to swing well because it is end loaded, with an unexpectedly high MOI.
As already discussed in the last section, increasing q by increasing MOI reduces swing speed. This will often result in a hit ball traveling a shorter distance despite the higher MOI because it becomes much harder to contact the ball with the sweet spot. For many youth hitters, lowering MOI will allow a player to hit the ball squarely on the sweet spot much more often, resulting in hits which travel further despite the lower q of the bat. On the other hand, a strong player with good mechanics may be able to go the other way, swinging a high MOI bat fast enough to make contact and benefiting with hits that go further.
I previously estimated that q varied between .12 to .15 for a 30-in, 18-oz bat. Different MOI accounts for some of this variation. A bat with q = .15 will have a higher MOI than the q = .12 bat. So my previous calculations for the potential for improved batted ball speed were too optimistic, as it assumed identical swing speeds between the q = .12 and q = .15 bats. In reality swing speed will be lower so some of the benefit of the higher q bat will be offset by lower swing speed.
Armed with an understanding of MOI, we’re now ready to list the various factors that purportedly impact bat q or swing speed. I discuss each of these factors in detail below:
- Trampoline effect improved by better materials
- Trampoline effect improved by double walls
- Balanced bat leads to higher swing speed
- Two piece construction and vibration dampening
- Bigger sweet spot
- Superior craftsmanship
- Forcing better swing mechanics
The trampoline effect is the key reason nonwood bats hit the ball further than wood bats. Aluminum bats were first introduced decades ago because aluminum doesn’t break as easily as wood. All aluminum bats are hollow. The first bats had similar performance to wood and were made with barrels that had thick walls to achieve high durability.
However, bat manufacturers discovered that making the walls thinner caused the bat to hit the ball further than wood bats. A ball colliding with a thin-walled aluminum bat does not compress as much, as some of the energy is transferred into bending the aluminum, which then springs back like a trampoline (the trampoline effect). Therefore, less energy is wasted compressing the ball.
The problem with the trampoline effect is that the thinner you make the aluminum walls of the bat, the more easily it will dent or crack and become unusable. The usual way to create thinner walls without risk of denting or cracking is to use better materials that are just as flexible yet stronger, such as a stronger aluminum alloy, a superior metal such as titanium, or a composite material. So that is exactly what bat manufacturers have focused on over the past few decades: develop ever thinner walls with greater trampoline effect.
Composite materials, usually graphite and carbon bonded together with resin, began to make their way into baseball bats 15 years ago. Within a few years, performance of the best composite bats exceeded those of the best aluminum alloy bats, thanks to a higher strength to weight ratio. In addition to potential for a much higher trampoline effect, composite materials allow for more flexible bat design in terms of exactly where the trampoline effect occurs, how weight is distributed and what happens at the interface between handle and barrel. See Daniel Russell’s article for a detailed, technical explanation about the advantages of composite materials.
Some materials have been so effective that bats based on them were too dangerous and had to be banned from play, as was the case for titanium bats produced in 1993 and certain composite bats produced in 2002-2003.
Today, the trampoline effect can be accurately measured in a lab, and therefore regulated. The college baseball regulatory body, NCAA, has gone through several rounds of standards. BBCOR is the latest and most stringent of the NCAA standards. The BBCOR standard is applied to both college and high school baseball.
The BBCOR standard which went into effect in 2011 is so strict that the trampoline effect on barrels is no longer significantly different than wood at the high school and college level. Home run rates were roughly cut in half for NCAA baseball after the 2011 BBCOR regulations went into effect and are now not much different from home run rates prior to the advent of aluminum bats in the 1970s.
At the youth level, there is a different and much looser standard called BPF 1.15 (Bat Performance Factor at or below 1.15). This standard gives so much leeway to manufacturers that there is wide variation in bat performance. As bat technology evolves, various youth baseball organizations occasionally push back by disallowing certain types of bats. For example, Little League banned composite bats altogether in 2011, though they now grant exceptions for composite bats that pass accelerated break-in testing.
UPDATE: Beginning January 2018, the BPF 1.15 standard will be replaced with a new wood-like bat standard called USAbat. (see USAbat Recommendations and Observations from Early Adopters)
So what are the materials that go into bats? They are either aluminum alloy or composite material. The handle and barrel of the bat are often made of two different materials, for two-piece construction. If they are made of one material (usually aluminum alloy) then it’s called one-piece construction.
Bat makers obtain aluminum from either Alcoa or Kaiser. Several alloys have been commonly used in bats over the past couple decades, which you can read about in great detail here and here.
According to these and other articles, 7046 is at the low end for aluminum alloys, with 7050 (also called CU31) a bit stronger, 7055 (also called c405) a good mid-range alloy, and alloys with scandium in them at the current high end (in order of increasing quality: C500, C555, Sc777, Sc888, and Sc900).
Unfortunately, bat makers rarely inform you which of the basic aluminum alloys the bat is made of (or is a slight variation of). For example, Alcoa’s 7055 alloy is called c405 when supplied to bat makers, and then each bat maker brands c405 differently. In most cases consumers have no way of knowing what alloy goes into a specific bat. Generally speaking, though, the higher the manufacturer’s suggested retail price of an aluminum alloy bat, the stronger the alloy. Stronger alloys allow bat makers to make thinner walls, which increases the trampoline effect. A weaker alloy used in the same bat design would dent too easily.
Note however that any alloy can be manufactured with walls that are too thin. Some specific models of expensive, high-end aluminum alloy bats in recent times have been denting too easily, according to some reviews.
Two inexpensive bats I purchased for my son last year had no information about the alloy used in the bat. I called DeMarini for information about one of them, a 2011 30-in, 18-oz DeMarini Vengeance. The customer service representative was friendly and told me what he could, but he had no way of knowing what alloy this was. Based on the full retail price, my guess is that both bats were made from entry level aluminum alloys, perhaps variations of 7046 or 7050.
Some bats do have the type of aluminum printed on the bat. For example, the Easton Speed Brigade S500 YB14S500 has 7050 printed on the barrel. Note that the name “Easton Speed Brigade” implies nothing about the material that goes into the bat. Even the more specific “Easton Speed Brigade S500” changes from year to year. You can only be confident in getting this exact same bat if it has the model number YB14S500.
Bat makers use stronger and more expensive alloys for their more expensive bats. I have seen the results on the field. However, I have no way of knowing whether the current model is any better (or worse) than the prior year’s model at a given price point. The brand name of the alloy will often change, but it isn’t clear if the alloy itself has actually changed. It is also unclear whether it has improved.
One thing I have learned from experience is that inexpensive bats often have cheap alloys that dent easily. T-ball bats that cost $30-$60 and have a drop 12 or drop 13 are usually lower grade alloys with thin walls to keep the weight down. This is fine for kids aged 9 and under but these are not durable bats. If an adult uses the bat for hitting big pop flies for practice, these bats may get dented. The bat my son used when he was 7 became dented and unusable after a coach hit fungos to the outfield with it for half an hour. I suspect that a strong 10-year-old hitter could dent a drop 13 T-ball bat with prolonged use.
“Drop” is the difference between the length and the weight of a bat. A 20oz, 30-in bat is drop 10. A 17oz, 30-in bat is drop 13. The higher the drop, the lighter the bat for a given length and the easier it will be to swing. Drop is a commonly used term to describe bats, and you will hear some coaches say that most kids below the age of 8 should use a drop 12 or drop 13 bat.
The other option for the barrel is a composite material. Composites can be made from many different formulas, but they have a few things in common. Historically, they have been less durable than aluminum (though some bat makers and resellers claim that the most expensive composite bats have become more durable than aluminum in recent years). The trampoline effect for composite bats gradually increases over time with use, increasing the q of the bat. Eventually the barrel will fail completely and have very little pop left. But just before that happens, the bat will deliver peak performance.
It is because of this increase in performance that some leagues (i.e. Little League) have banned composite bats altogether. However, composite bats now go through accelerated break-in testing and are permitted for use when they are at or below the permitted performance limits during the entire lifetime of the bat.
Some manufacturers, such as Easton, are now claiming that a break-in period is no longer required for their bats. From talking with people in the industry, I believe this claim is an exaggeration. A composite bat will still break down and get hotter over time, but to a lesser degree than composite bats from a few years ago. This is because composite bats are now made with greater durability than in prior years. There will still be a performance improvement over time, but it will be slight.
Most bat makers recommend avoiding extreme heat (car trunk on sunny day), and not using a composite bat below 60 degrees Fahrenheit or with the hard, dimpled balls used in batting cages. Despite these caveats, composite bats continue to grow in popularity, perhaps due to extra design flexibility which can allow for decreased sting, larger barrels, and lower MOIs (Moment of Intertia or Swing Weight). It is also possible that Easton, DeMarini, and other top bat makers are putting more resources into further developing composite technology, and therefore composite bats are improving faster in recent years than aluminum bats at these larger companies.
Even though composite bats can theoretically be designed with a much higher trampoline effect than aluminum, they are not designed that way due to regulatory limits. This means that performance for the better aluminum alloys is not too far behind composite, at least in terms of the trampoline effect.
I am somewhat puzzled by the lack of effort to develop better one piece aluminum alloy bats by the more established companies. This may be because composite technology allows greater flexibility of design. The current trend is to push bats with bigger sweet spots and lower MOI, an area where aluminum cannot effectively compete. However, not all players or coaches prefer this style of bat. From what I’ve been able to gather, more innovation is happening with aluminum bats from smaller companies such as Anderson, Baden Sports, and Marucci Sports.
Double walled bat construction has been popular for softball but not baseball. The only double walled baseball bat model currently produced is the Anderson Techzilla. This is quite curious, because double walled aluminum outperforms single wall aluminum according to scientific studies and is very competitive with legal, high end composite materials in terms of trampoline effect. The basic idea is to have an outer wall which is much thinner than a single wall aluminum bat to provide greater elasticity, while the inner wall prevents denting.
Bat manufacturers often push balanced (Low MOI) bats as best for contact hitters. Lowering MOI, or “swing weight” will decrease q while increasing bat speed. Increased bat speed will usually lead to better hitting results, as discussed earlier. But there are two ways to lower MOI. You can pay hundreds of dollars to get the same length and weight of bat with the lowest possible MOI. Or you can simply get a less expensive bat that is smaller and/or lighter.
In other words, the main things the “balanced” bat gets you over a smaller bat is an inch or two of greater bat length for greater plate coverage, a slightly faster bat speed due to the longer distance traveled by the bat’s arc in the same amount of time, and perhaps a slightly larger sweet spot. Extra plate coverage may help with outside corner pitches, and a larger barrel and/or sweet spot can increase chances of contacting the ball with the sweet spot. Probably the biggest benefit is the slight bump in bat speed.
Other than these benefits, I don’t see how an expensive balanced bat can generate better hitting results for a 10-year-old batter than a less expensive, more end-weighted bat that is 1-2 inches shorter with the same MOI, if the same materials are used. It is also possible to get the same length of bat at a lower weight in many cases. Instead of getting a 30-inch bat weighing 20oz that has weight shifted towards the handle to lower the MOI, you can get a 30-inch 18oz bat that will have about the same MOI, usually at a lower cost.
Paying top dollar for a balanced bat makes a lot more sense for high school or college players. This is because bats are strictly regulated to be drop 3 bats. A 31-inch-long bat cannot weigh less than 28 oz. Players must use BBCOR certified bats (updated in 2017) and none are available less than 30” long. Most high school players use a 31” or 32” bat. A shorter player using a 31” bat length is going to want to minimize the MOI of the 28-oz bat as much as is permitted by NCAA regulations. At this level, an expensive, high quality, balanced bat can be well worth the additional cost.
Two-piece bat construction is when the barrel is made of one material and the handle is made of a different material. It could be a composite handle and an aluminum alloy barrel, or it could be two different composite materials. There has been little scientific study on the impact of two-piece construction on batted ball speed (BBS), so far as I have been able to find. Some marketing materials from bat makers and bat resellers claim there is a whip effect, where the barrel trails behind the handle slightly and then whips forward just as the bat contacts the ball. This hasn’t been much studied. Baseball scientist Daniel A. Russell believed, as of early 2007, that if there is a positive whip effect from handle flex, it would be very small, and perhaps as likely to be negative as positive.
It is also worth noting that composite handles can be designed to flex. The whip effect from composite handle flex is more significant than the whip effect caused from having a two-piece design.
A two-piece bat design does allow for a vibration dampener to be placed in the connection piece. This really does work as anyone swinging these bats will confirm. However, it is unclear whether this is an advantage or disadvantage. Batters don’t like the stinging sensation that occurs when hitting a ball off the sweet spot. For some batters, knowing the bat will never sting may increase confidence and encourage swinging the bat harder. Some people believe this automatically happens at an unconscious level. Furthermore, the ball feels as though it has pop off the bat every time you hit it, because you never feel a sting. But not feeling the sting may be a disadvantage because it removes the feedback of mis-hit balls.
This is why I don’t like Amazon reviews for two-piece bats or any bats for that matter. You will read many reviews that say little more than “this bat has great pop.” This may mean that it never stings, so it feels as if it’s popping off the bat. It may mean that it makes a better sound. It may have a bigger sweet spot so that the player is much more often hitting the sweet spot. Or it could be that the bat has a lower MOI than the previously used bat, so the player can swing it faster, hit it harder, and more often hit the sweet spot. It could also be the hoped-for greater trampoline effect—but this is by no means assured.
Batted balls hit off a two-piece bat with vibration dampener may come off the bat slower because:
- A small portion of vibrational energy that might go back into the baseball is instead dissipated in the vibration dampener.
- Player development may be inhibited. The player gets little or no tactile feedback about where the best part of the sweet spot is. With a one piece bat, the sting hurts and over time, batters learn to “square up the bat” (aim the sweet spot at the ball) better. Without the tactile feedback of the sting, hitters with two-piece bats may develop more slowly than they otherwise would have.
DeMarini claims to have come up with a design that bounces the vibration back into the barrel and into the ball on some of their more expensive bats. This has not been vetted by scientific study, so whether DeMarini has achieved this goal is open to speculation. However, even if DeMarini has not yet succeeded, it may point to an area where bat makers will make progress over the next few years.
Perhaps the biggest advantage of two-piece construction is the added design flexibility in distributing weight across the bat. Whether lowering MOI for a balanced feel, raising MOI for an end-loaded feel, or simply creating something different that a player may prefer, the added flexibility makes for bats that really do have a different swing feel, and for some batters this may make a positive difference.
A bigger sweet spot is another way bat makers attempt to help the hitter. I already mentioned previously that the ball is rarely hit by the best part of the sweet spot of the bat at the youth level, or any level of baseball. The hard way to get more sweet spot contact is to improve hitting mechanics. The easy way is to use a bat with a bigger sweet spot.
What do I mean by bigger? This could mean that the fat part of the bat is longer, that the portion of it that is “sweet” is a greater percentage, or that the barrel is fatter. The baseball has a greater chance of contacting the sweet spot if it’s bigger. Some bats with very large sweet spots are more difficult to swing because of the way the weight is distributed. For a bigger sweet spot to result in more success, the bat must be designed in a way which is just as easy to swing as a bat with a smaller sweet spot. A great balance between massive sweet spot and easy-to-swing is what makes some bats, such as the Easton Mako I mentioned in the introduction, so popular.
How “fat” a bat can be is regulated by age and is different depending on the organization. 2 1/4 inch bats are legal at all youth levels but the legality of 2 5/8 inch bats and 2 3/4 inch bats varies by age and organization.
I have little doubt that a bigger sweet spot can lead to better batting results. I observed a batter on my son’s team who batted much better over a several month period compared to the previous season. What I hadn’t noticed was that he had changed to a 2 5/8” barrel bat. Our competitive summer team went to a tournament where 2 5/8 bats were not permitted. He went back to his old 2 1/4 inch bat and went 1 for 10 in 4 games, with 7 strikeouts. That’s a .100 batting average, compared to the .294 batting average he had in games in which he was permitted to use his big barrel bat.
This anecdote is not statistically significant, but it illustrates both the pros and cons of a bigger sweet spot. The pro is that you’ll get better contact more often and therefore get more hits. The con is that you may become dependent on the bigger sweet spot size, and no longer able to hit with a 2 1/4” bat when you need to. You can get away with being less precise with hitting mechanics and no longer get obvious feedback from mis-hit balls. As with vibration dampening, I think it’s a judgment call as to whether it’s more important to boost the player’s short-term results (and confidence) or increase skill level over a wider range of bats.
For a player who is already confident and who hopes to play baseball in high school or possibly beyond, it may be better to do whatever it takes to foster skill development and prepare for the more heavily regulated BBCOR bats in high school (and for the optimistic, the wood bats required in the minor leagues). For that, it may make sense to stick with 2 1/4” barrels that do not have massive, extended sweet spots. On the other hand, the player who is in it for fun and likely to lose interest in baseball before high school is better off with a big-barrel bat. Getting hits is more fun than getting outs, and that is more likely to happen with a bigger barrel, at least in the short run.
Superior craftsmanship is a catch-all phrase I use to cover bat attributes that are not much discussed or advertised but will nevertheless have an impact on bat performance over the lifetime of the bat. Examples include:
- The trampoline effect is uniform throughout the fat part of the bat (except edges)
- If the barrel is made from aluminum, it is durable (does not dent or crack for years)
- If the barrel is made from a composite material, it lasts a long time before it goes dead
- The tape on the handle is durable and never peels or unravels
- The end cap and knob are shaped correctly and made of high quality materials. The end cap especially can have significant impacts on the sweet spot size and performance. Sometimes end caps pop off the end of a bat. Not good.
Unfortunately there is no way for a consumer to know in advance how good craftsmanship is for a particular bat. I’ve encouraged my son to experiment with bats lately. We have a hand-me-down 10-year-old Easton Octane c405 aluminum bat so heavily used that I needed to wrap the handle with more tape. The other day my son hit 8 balls off a tee with his 2011 DeMarini Vengeance with less than a year of use and the Easton Octane, both one-piece aluminum bats. On good hits, the ball travelled 10-15 feet further with the Octane. The Octane’s aluminum barrel was clearly durable to be doing so well after so much use, though it was also probably a higher grade of aluminum to begin with.
From reading through hundreds of consumer reviews, I am convinced that sticking with a well-known brand name such as Easton or DeMarini does not guarantee craftsmanship. For example, the 2014 drop 13 Easton S3 was supposed to be a high-end one piece aluminum bat with a THT100 scandium alloy, at $160. Perhaps the walls were too thin or perhaps quality control was inconsistent as there were some complaints about denting after little use. In fact, I know two players in our league who both liked this bat but dented 3 of these between them.
The last category of bat improvements is forcing better swing mechanics. So far as I know, the Axe Bat is the only bat currently in this category. Ted Williams says “swinging a bat is like swinging an axe” in his book the Science of Hitting. He even trained in the off season by chopping wood with an axe.
The Axe bat’s handle is oval and asymmetrical with an angled knob like that of an axe. This design is intended to position the wrists for optimal power, which apparently doesn’t come naturally to most hitters. The knob also has ergonomic benefits.
The Axe bat approach strikes me as more interesting and innovative than simply making walls thinner with a better material. My son loves Axe bats and I’ve written three reviews about his experiences: big barrel MB50, Origin 2016 drop 12, and a pair of Axe Bats from 2017. There is some science behind this bat, and a recent empirical test supports claims by the producer of this bat, Baden Sports.
Bats for Power Hitters vs. Bats for Contact Hitters: A False Dichotomy
Of all the confusing marketing materials for bats, the one which confounds me the most is the discussion regarding “balanced” bats and “end loaded” bats. Adult wood bats are all end loaded because the barrels are solid. Nonwood bats can be made in the end loaded style, or have weight shifted towards the handle for lower MOI, the so-called “balanced” feel.
There are two ideas that I see over and over that are more misleading then they are helpful:
- Misleading idea #1: High MOI end loaded bats are for power hitters, while low MOI balanced bats are for contact hitters.
- Misleading idea #2: To lower the MOI of a bat, get a balanced bat.
It is true that the bigger and stronger players with better mechanics will be able to swing bats with higher MOI. Fine. But you can get higher MOI either by getting the same size and weight of bat with more of an end loaded feel, or you can get higher MOI by getting a bigger and/or heavier bat. Either way increases MOI.
The same thing is true in the other direction. The contact hitters who are trying to get singles by hitting the ball into gaps will want a low MOI bat. This can be accomplished by using a more balanced bat of the same weight and length, or it can be done by changing to a smaller bat length and/or weight. Either way decreases MOI.
It is simply a matter of the style of bat you prefer. A contact hitter can use an end loaded smaller bat or a more balanced same-size bat. A power hitter can use an end-loaded same-sized bat or a balanced, bigger bat. The best way to find out is to test swing a bunch of different bats from teammates.
What is the Best Bat to Buy?
The best bat to buy is going to vary based on age, size, and skill level. Personal preference will also play a part. You may be able to narrow down to just a few bats with size, price, and materials criteria. Choosing among the remaining few may require a few practice swings against live pitching. My guess is that preference is largely determined by the varied distribution of weight in each bat.
I recommend below the best bats I happen to be familiar with. By no means have I seen every bat being used in the field, so no doubt I’ve missed some great bats. However, I will periodically update my recommendations when I come across better values or better performers.
Here is some generic advice that applies to all ages:
- February 2016 UPDATE: Weigh your new bat at the store or when you get home. It may weigh anywhere from 1 to 3 ounces more than is stated on the bat. Manufacturers have become wildly inaccurate in reporting bat weight in recent years, which may result in a too-heavy bat that your kid can’t swing well. Much thanks to reader Chad Miller (patent attorney and former engineer), for pointing this out to me a few months ago. I have since weighed many brands and models of bats and verified that most youth bats produced over the past few years are overweight by 1 to 2 ounces.
- Look for “approved for” and the name of your type of league printed on the bat (Little League, PONY, Babe Ruth, etc.), as well as the USSSA stamp and BPF 1.15. The BPF 1.15 designation means that the barrel of the bat has been tested and found not to exceed a bounciness measure of 1.15 (wood is less elastic and typically just above 1.05).
- November 2016 UPDATE: Bats you purchase today will not permitted for use in PONY or Little League after January 1, 2018, when the new USAbat standard goes into effect (see USAbat Recommendations and Observations from Early Adopters). However, they can still be used for USSSA travel ball tournaments.
- 2 3/4 inch barrels are not permitted for many levels of play in many leagues, so I’m not going to recommend any of these models. 2 5/8 inch barrels are permitted in most but not all leagues. Be sure to check if your league allows 2 5/8 inch barrels for your player’s age level.
- Some bats marked “T-ball” bats are not permitted after the age of 6 or so, depending on your league. If you get such a bat, understand that you may have to stop using it when your kid moves up to the next level.
- Do not assume that getting a particular brand of bat is the same as other bats with the same name. For example, Easton has numerous different versions of the “Power Brigade.” If you know the bat you want because your kid borrowed it from a teammate, take a picture of the information on the bat so you can match the model number with the bat you buy.
- There is a wide range in quality of materials and craftsmanship that go into a bat. Generally speaking, the higher the manufacturer’s suggested retail price, the better the quality. Note, however, that last year’s top of the line is still going to be a great bat, and you may be able to get it for 50% less than its year-ago cost.
- It is important to understand that the static weight listed on most bats is only a rough reflection of how difficult the bat is to swing. High MOI bats with “end loaded” weight are harder to swing than low MOI bats that are “balanced,” given the same static weight and bat length.
- DeMarini differs from the rest of the industry by listing “swing weight” instead of “static weight.” This started a couple years ago. Weigh a DeMarini bat and the weight may be a little different than what is printed on that bat. This is a good thing, as the swing weight takes into account the MOI of the bat. This means that all DeMarini bats are comparable with each other in terms of how difficult it will be to swing the bat—and that matters far more than the static weight of the bat. However, this also means that DeMarini bat weights are not strictly comparable to bats from other manufacturers.
- Many bats have a 6 month or 12 month warranty, and some have a 30 day money back guarantee if you don’t like the bat. If you choose to buy an expensive bat, make sure it has a warranty in case the bat dents or cracks within the first few months of use.
Player size and skill roughly correspond to age, so I’ll break down recommendations by age.
What Bat is Best for a 5 to 6-year-old?
There is little to be gained by buying an expensive bat for a 5 to 6-year-old. All that matters is getting an appropriate size and weight. An expensive bat will add at most 6 feet of distance over a cheap bat, and only for the biggest kids with the best hitting mechanics when they hit the ball perfectly.
One could argue that bats which enable faster swing speeds or better mechanics might be worth something. However, at this age the batter matters far more than the bat. The emphasis should be on teaching proper mechanics and getting in lots of practice swings, not an expensive bat.
Bat weight should be between 13 and 17oz and length between 24″ and 28″, depending on the size of kid. The very biggest 6-year-olds might be able to use a 28″, 17oz bat. More typical will be a 26″ bat weighing 13oz or 14oz. When in doubt, go smaller and lighter. At this age, kids want to have fun hitting the ball, and that is going to happen much less often with a heavy bat. If you accidentally get too big a bat, you can always have your kid borrow a lighter bat during games until he grows large enough to use his new bat. Alternatively, choking up on the bat is a way of reducing swing weight.
As discussed earlier, not all bat weights are the same, due to how the weight is distributed. Not many bats for the youngest ages are heavily end weighted, so stated bat weights at this age are generally comparable.
One important piece of advice: Don’t let an adult or older kid use one of these drop 12 or drop 13 bats for batting practice or fungos. Most of them are made of the weakest kind of aluminum alloy, and the walls are thin to keep the weight down. The bat will get dented if used by an adult or strong, older kid.
The one exception to this is the Axe bat, which is made of a more durable alloy than is typical for Tball bats, and is also engineered to be stronger on the portion of the barrel most likely to contact the ball.
If I were to buy a bat for a 5 or 6-year-old today, I would consider an Axe Bat not just for the durability reason, but also because the axe-like knob forces one part of hitting mechanics to be correct (where the hands are when the bat contacts the ball):
Axe Bat 2017 Hero T-Ball L129E (-11)
Another bat that is both durable and effective is the Easton S500, a bat I even more strongly recommend for 7 to 8-year-olds:
Easton Speed Brigade S500 Youth Baseball Bat
Apart from going too big, there’s really no way to go wrong at this age. If you do end up getting something too heavy to swing but your kid likes it, just wait a few months and he’ll be big enough to swing it.
What Bat is Best for a 7 to 8-year-old?
For most players, the same advice for 5 to 6-year-olds applies to 7 to 8-year-olds, but with a slight increase in size and weight of bat. Bats should weigh between 14 to 19 oz, and be between 26″ to 30″ long. The only reason I go so high with the range is that there is occasionally a really large and strong kid (over 53″ tall) who might be able to handle a 30″, 19oz bat. But the vast majority of players who use such a big and heavy bat will have a slow swing speed and therefore struggle at the plate.
A more typical bat for this age is 27″ and 16oz (drop 11) for a 50-inch tall 8-year-old, and something a little smaller and/or lighter for a 7-year-old or short 8-year-old.
By the age of 8, some players participate in higher level summer play with an all-star or travel ball team. These are referred to as 8u players. I have seen quite a few 8u players with $300-$400 high-end bats at this level and even a few in our local PONY league with such expensive bats.
If you understand the physics of the bat/ball collision I described above, then you know that for players of average size and weight, the best this can do is cause the batted ball to travel further by 6-8 feet. At this age, you would be far better off spending that same $300 on hitting lessons with an experienced hitting instructor. Or better yet spend time pitching to your kid at your local park.
The players who will benefit most from a high end bat are unusually big, heavy players with a very fast swing that are already consistently hitting the ball to the outfield with their existing inexpensive bat. A high end bat will add perhaps 8′ to 10′ feet of distance on a perfectly hit ball for such a hitter. For the average hitter, it will add little to batted ball distance.
One could argue that some bats speed up the swing or improve mechanics. However, at this age the batter matters far more than the bat. The emphasis should be on teaching proper mechanics and getting in lots of practice swings, not an expensive bat. If bat speed isn’t fast enough, switch to using a smaller and/or lighter bat.
It is possible to get a bigger barrel which makes it easier to get a good hit. By bigger, I mean either longer or fatter. In some leagues, you can’t go higher than 2 1/4″ thickness at this age so if you want a fatter barrel, you should check to make sure your league allows it. You might want to skip getting a fat barrel even if your league allows it, because your kid may have trouble swinging a bat with such a big barrel.
Whether or not to get a bigger barrel with a bigger sweet spot will depend to some extent on how serious your kid is about baseball and your beliefs about what kind of bat is best for long-term development. My son is very serious about his long-term baseball aspirations. He has never used a 2 5/8″ bat, and I will discourage him from using one if he expresses an interest before the age of 12, when fat barrels become the norm. My theory is that by using a 2 1/4″ bat with a normal barrel and some amount of bat vibration, he will forced to learn how to “bring the bat into the zone” in such a way that the ball hits a small sweet spot. I believe that using a bat with a smaller sweet spot will lead to better hitting skill in the long run.
All this should be taken as speculation on my part. I haven’t come across any scientific study to confirm or deny my hypothesis that big barrel is detrimental to long-term hitting development, and I don’t have any idea if my son will be able to hit much more difficult high school pitching when he comes of age with heavily regulated BBCOR bats. Nevertheless, until proven otherwise, I will encourage him to stay away from big barrel bats or bats that heavily dampen vibration.
On the other hand, if you have a player that enjoys baseball but doesn’t take it too seriously and you doubt he will play for more than a few years, then by all means get a big barrel bat. In the short run it will be easier to put the ball in play and reach first base safely. And that will without doubt be more fun.
Many coaches believe that confidence is more important to hitting than anything at this age. If having a big barrel, or dampened vibrations, a favorite bat color, or any other factor helps with confidence, then hitting results will likely improve. According to this line of thinking, bad habits can be corrected at a later age, while without confidence the player has little chance of success at the plate.
The contrasting view to this is that bad habits are harder to break the longer you practice them, so the earlier you get it right, the better. Long-term gain sometimes may require some short term pain.
At any level, the most important thing by far is not to get a bat that is too heavy. If you want a 29″ 17-oz bat that is light enough for your player to swing, one possibility is to spend more money on a high tech bat that lowers the MOI by using a very light material for the barrel and shifts the weight towards the handle. Or you can just get a 28″ 16-oz bat that has a similar or even smaller MOI but costs $80 or less.
Unfortunately for consumers, MOI is not printed on the bat or even obtainable from manufacturer web sites. Borrowing and testing teammates’ bats is a rough way of discovering a bat with a low enough MOI.
Among the various bats I’ve seen used among players between the ages of 7 and 10, two inexpensive bats have particularly impressed me. One is the Easton Speed Brigade S500. It is a balanced, drop 13, one-piece aluminum bat that can be purchased in any size between 27″ and 32″. There are plenty of other reasonable bats to be had for $60 but I point out this one because I’ve seen it used by several players, including one who switched from another bat to this one and immediately had more success. I also like that the barrel specifically says that 7050 is the type of aluminum that goes into it. While not a high-end aluminum, it is stronger than 7046 and I have yet to see one of these bats dented.
Easton Speed Brigade S500 Youth Baseball Bat
The other terrific choice is the following Axe Bat (see my review), which I have seen lead to even more dramatic improvement. Part of the improvement may be due to improved hand position upon contact, which is forced upon batters by the axe-like shape of the knob. This bat is now my favorite among sub $100 bats:
2017 Axe Bat Origin Youth (-12)
If you want to go for a bigger barrel, first check to make sure your league allows 2 5/8″. Most are too heavy but the following two are not too difficult to swing.
The best price I’ve seen on a big barrel that a 4′ 6″ player has a chance of swinging well is this version of the Axe bat (here’s my L144E review):
Axe Bat 2018 Origin Big Barrel drop 10 which is also available on Amazon. If you purchase direct from the manufacturer of the Axe Bat, be sure to use code JGOL10 for a 10% discount.
I have also seen the following big barrel bat costing around $150 – $200 used successfully by several players in our league:
Louisville Slugger Senior League 2 5/8-Inch Catalyst Baseball Bat
If you delay buying a fat barreled bat until the player is over 4 1/2 feet tall, there are many value-priced, heavier choices.
There are some very good, moderately priced 2 1/4″ models that are an upgrade over the s500, such as:
Marucci Hex Alloy Youth Baseball Bat
And yes—if your player is consistently hitting the ball and participating in high level summer play, the magic bat I introduced at the beginning of this post is indeed a good one for those who prefer a balanced bat. It is likely to result in a greater percentage of sweet spot contact:
Easton MAKO COMPOSITE Youth Baseball Bat
An up and coming alternative to Mako that is beginning to show up in our area and getting rave reviews is the fat barreled Combat Maxum:
Combat Maxum MAXSL112 2 5/8″ Drop 12
Those who prefer a more end-loaded feel will prefer the following Easton composite model. I have seen several sluggers hit the ball very far with the prior year’s model (XL1):
Easton MAKO XL COMP -10 Youth Baseball Bat
Those who like the feel of a two-piece design with an aluminum barrel may prefer this less expensive bat from DeMarini:

What Bat is Best for a 9- to 10-year-old?
As players get older, differences between the most and least skilled players widen. Swing speed varies dramatically from less than 20 MPH for small beginners lacking in athleticism to 45 MPH for big kids who have above average hitting mechanics.
Most advice from younger ages continues to apply to 9- to 10-year-old players with average or below average swing speed. I won’t repeat it again, other than to say that the range of size and weights again increases. Size and weight of the player is much more important than age, but obviously the average size and weight of player increases with age.
A 14 oz, 27″ bat is the smallest I see used among 9- to 10-year-olds, while the largest is a 21 oz, 31″ bat used by the biggest kid in the league. That’s a wide range, because the kids range in height from 48″ to 62″. The right bat for an average sized 10-year-old would be 18oz, 29″, while the right bat for an average sized 9-year-old would be 17oz, 28″. Again, recall that not all bat weights are the same. Look for words like “balanced” or “end loaded.” If a bat is described as balanced, you may be able to get away with a slightly heavier or longer bat, but you’ll need to go a little lighter for an end loaded bat.
Even for this older age, I tend to believe that spending $300 on a bat is unnecessary for most rec league players. The rule of thumb continues to be that players who already consistently hit the ball hard are going to be the only players who significantly benefit from an expensive bat. A player who rarely contacts the ball on the sweet spot well may benefit from a bigger barrel, but the other aspects of a bat that drive up the cost into the $200-$400 range aren’t going to matter much until swing speed exceeds 40 MPH.
There are 96 players in our 9- to 10-year-old division. Based on the math I went through above and my knowledge of the players in our league, my guess is that somewhere between 15 to 30 of them might actually see a significant and noticeable benefit from using a high-end bat. The rest are not swinging the bat fast enough to make more than a few feet worth of difference. As with any age range, the most reliable way to improve hitting is to increase swing speed, and a simple and inexpensive way to do this is to switch to a smaller and lighter bat. For the majority of 9- to 10-year-old players, switching to a lighter bat will make more of a difference than switching to an expensive bat.
At the more competitive levels seen in all-star play and travel ball, most 10u players will be swinging the bat at 40 MPH or faster and a good number of 9u players will swing that fast as well. Not surprisingly, that is when you start to see a lot of $200-$400 bats. Using the same math I went through earlier, you can calculate that a player with a 40MPH swing will add 12 feet to the distance to a perfectly hit ball when using a high-end bat instead of a low-end bat, while a player with a 45 MPH swing can potentially add 14 feet. These extra distances are significant as an extra 12 to 14 feet can sometimes be the difference between a caught ball or an extra base hit. The extra batted ball speed can also turn routine grounders into ones so hard that all but the best fielders won’t be able to stop them.
Do note that a great bat is limited in what it can do for a player. I have already mentioned the rule of thumb that the players who benefit from an expensive bat are the ones already consistently hitting the ball hard into the outfield. I have seen many players who are able to consistently hit the ball into the outfield in rec league, but can no longer do so at the higher levels of play. This is because pitching gets better.
An expensive bat isn’t going to help a player learn how to hit a changeup or curveball, and it won’t help much with high velocity pitching either. Hitters with a long swing that works for slow pitching will need to make their swing shorter and faster to deal with tougher pitching. Switching to a lighter and smaller bat can help with that, but switching to a more expensive model can only help if it reduces the bat’s MOI (swing weight). I have seen entire teams using expensive bats unable to get more than a couple of quality hits per game against strong pitching.
There is a wide variety of bats available ranging in price from $20 for a closeout special, all the way to $400 for high end composite bats. I present my recommendations ordered approximately by price.
The 2 1/4″ Easton S500 with durable 7050 aluminum alloy is a great entry level bat for 7 to 10-year-olds for reasons I already mentioned above. It comes in larger sizes so can be used for small 11-year-olds as well who want a long, light bat at drop 13.

Also already discussed is this slightly more expensive Axe bat which helps correct some mechanics thanks to the axe-like knob:
2017 Axe Bat Origin Youth (-12)
Another premium one-piece aluminum bat is from aluminum-specialist Marucci :
Marucci Hex Alloy Youth Baseball Bat
Big barrel bats are mostly expensive at this age, though there is one low cost model that bigger-than-average 10-year-olds should be able to handle:
Louisville Slugger 2014 Warrior Sr League (-9) Baseball Bats
A model that my son has used very successfully since November 2016 (when he was 4′ 8″) is this big barrel version of the Axe bat (here’s my L144E review):
Axe Bat 2018 Origin Big Barrel drop 10 which is also available on Amazon. If you purchase direct from the manufacturer of the Axe Bat, be sure to use code JGOL10 for a 10% discount.
More expensive, but very effective in our league, is this big barrel from Louisville Slugger:
Louisville Slugger Senior League 2 5/8-Inch Catalyst Baseball Bat
While not used by anyone in my league, the following value priced, balanced, composite bat gets great reviews everywhere:
DeMarini 2015 Youth NVS Vexxum -12 Baseball Bat
The high-end bats suitable for summer play at the 7- to 8-year-old level are also suitable for the 9- to 10-year old level. The magic bat described at the start of this article is a good match for larger-than average 9- to 10-year-olds who prefer balanced bats and is likely to result in more frequent contact with the sweet spot:
Easton MAKO COMP -11 Youth Baseball Bat
An up and coming alternative to Mako that is beginning to show up in our area and getting rave reviews is the fat barreled Combat Maxum:
Combat Maxum MAXSL112 2 5/8″ Drop 12
Those who prefer a more end-loaded feel will like Easton’s XL1 line, relabeled the XL in 2015 for the youth version. I saw some of the bigger 10-year-olds hit the ball nearly 200 feet with the 2014 version of this model:
Easton MAKO XL COMP -10 Youth Baseball Bat
DeMarini has a slightly less expensive two-piece bat that also pleases fans of the end loaded style:
DeMarini 2015 Voodoo Overlord Youth Baseball Bat (-13)
What Bat is Best for an 11- to 12-year-old?
The 11-12 age range is more challenging to write about because of variety, both in players and in bats.
Players range in size from 4 to 6 feet tall, while experience ranges from novice to 7 years, including several years of travel ball or all-stars for some.
For players who are short and have less than 2 years of experience, the advice given for 9 to 10-year olds in the previous section is going to be more appropriate. It is also worth reading the 9- to 10-year old section for the discussion around which types of bats are appropriate for which types of players, which I won’t repeat in this section.
This section will also not be appropriate for players over 5′ 6″ tall. I will write a section for 13-year olds in 2017 that also works for tall 12-year olds, but at this point it’s too far outside my experience.
The recommendations in this section target the majority of 11- to 12-year olds players who have at least 2 years of playing experience and who are between 4′ 6″ to 5′ 6″ tall.
I’m skeptical of the value of expensive, high-end bats for kids aged 10 or below, as I’ve made clear throughout this article. However, starting at the age of 11, buying a more expensive bat makes sense for many players, for the following reasons:
- Many players with slower swings drop out of youth baseball by the age of 11. Most of the players who remain will have swing speeds of at least 40 MPH.
- As discussed previously, a high-end bat in the hands of a player swinging at 40 MPH can add up to an additional 12 feet to balls hit perfectly off the sweet spot. For those who swing faster the extra distance will be even higher.
- Fielding is better. Hitters will reach base less often from errors than they used to. Given good fielding, there is ample evidence that hitting the ball harder increases the chance of getting to first base safely.
- Pitching is better. Better bats can in some cases give batters more of a chance to make contact against tougher pitching.
The average 12-year old player (who is 12 1/2) is about 5 feet tall, while the average 11-year old player is 3 inches shorter. Because there is a limit to how fast a kid can swing a bat, players will do well to abandon their drop 13 bats in favor of a heavier bat. Kids below 5 feet tall will want to be in the drop 12 to drop 10 range, while bigger kids will range from drop 10 to drop 8.
A 30″ bat will be typical, or 31″ for bigger kids, with weight ranging from 19 oz. to 23 oz. Most players will struggle with 32″ bats. Even big 12-year-olds with the most expensive, low MOI bats often have difficulty controlling a 32″ bats, though occasionally you run across a player who can handle 32″. Increasing weight beyond 22 oz or choosing an end loaded style of bat will be a better option than going beyond 31″ for big players ready to swing a higher MOI bat.
Also worth considering at this age is having one bat for practice, and a different bat for games. Practice bats are often an ounce or two heavier or more end-loaded to help build muscles. Using a wood bat or one-piece aluminum bat (without jumbo-sized sweet spots) for practice is best so that players get the vibrational feedback from poorly hit balls needed to help improve their swing. Having a bat during a game that has a bigger sweet spot and features that help swing speed or pop may enable the player to get to get to first base safely off poorly hit balls more frequently than if they were using the practice bat.
The variety of bats for this age range is very wide, partly because 2 5/8″ or “fat barrel” bats are a legitimate option. The following recommendations are by no means an exhaustive list of the better bats. I have purposely chosen this set of bats to expose a wide range of styles.
The 2 1/4″ Easton S500 with durable 7050 aluminum alloy is a solid entry level bat for 7 to 10-year-olds for reasons I mentioned above. However, it is too light for most 11- to 12-year olds at drop 13. A drop 9 version was produced in 2014 which is appropriate for players of above average height and/or weight. Though Easton no longer makes this bat, it can sometimes be found at Amazon:
Easton 2014 S500 SL14S500 Baseball Bat (-9) or (-5)
As I mentioned in earlier sections, I have liked the Axe Bat Origin even better than the drop 13 S500 (see my review). It is more end-weighted and an ounce heavier so the 30″ version is definitely well suited to short and slender 11- to 12-year olds. It’s the bat my short son used and loved when he was 11 and under 4′ 7″:
2016 Axe Bat Origin Youth (-12)
Another older Easton model I like is the entry-level 2 ¼” aluminum drop 10 Easton Magnum. It has more of an end loaded feel so may actually have a similar swing weight. It is occasionally available for a very good price on Amazon, if it is available at all:
Easton Magnum Youth Baseball Bat (-10)
The 2 5/8″ Warrior from Louisville Slugger is an entry-level big-barrel aluminum bat that also uses the durable 7050 alloy. At drop 9, it is only appropriate for average sized 12 year olds or tall 11-year-olds.
Louisville Slugger 2014 Warrior Sr League (-9) Baseball Bats -9
However, for a little more money, the entry level big barrel version of the Axe bat is a fantastic bat that my son has been using since November 2016 with great success (here’s my L144E review):
Axe Bat 2018 Origin Big Barrel drop 10 which is also available on Amazon. If you purchase direct from the manufacturer of the Axe Bat, be sure to use code JGOL10 for a 10% discount.
The Anderson Techzilla bat is so interesting to me that I purchased the 30″, 21oz Techzilla 2014 XP model for my son to try out when he was 10. As I have mentioned many times throughout this post, the trend in recent years has been towards high-end, long-barreled composite bats that have a low MOI. The exact opposite of this trend is the Anderson Techzilla, which is so heavily end-loaded that it feels harder to swing than some solid-wood bats. It is also not made of composite, but rather double-walled aluminum. The trampoline effect for double walled aluminum bats is higher than single walled aluminum bats and is competitive with standards-compliant composite bats. Anderson is the only manufacturer producing such bats for baseball.
My smaller-than-average son could not get good hits with this too-heavy bat at first, when he was 10 years old. However, in November 2016 he is almost big enough to swing it at 4′ 8″, 75 lbs, and he is hitting some bombs when he’s able to swing it well. Having also seen some other players experiment with it, I believe that there are some players who will love this bat. A very good hitter with loads of upper body strength will be able to frequently hit balls to the fence with this bat, once the player gets used to the end-loaded feel.

Anderson Techzilla 2.0 (-9) Little League Baseball Bat
Two high-end bats from the 9- to 10-year-old ages also work well at the 11- to 12-year old level as well. The regular Easton Mako is a good match for small to mid-sized players who prefer balanced bats and often produces good results for poorly-hit balls in addition to well-hit balls:
Easton MAKO COMP -11 Youth Baseball Bat
The Easton’s XL1 (relabeled Mako XL this year for the youth version) is end-loaded. I see some of the league’s top sluggers hitting the ball very hard and far with the 2014 version of this model:
Easton MAKO XL COMP -10 Youth Baseball Bat
This section ends with one of the high-end, big-barrel bats that also happens to be moderately priced, the 2 5/8″ DeMarini Voodoo Overlord FT, a two-piece bat with a high-end aluminum barrel that is universally praised:
DeMarini 2015 Voodoo Overlord FT Youth Big Barrel (2 5/8-Inch) Baseball Bat (-9)
Tips for the Cost Conscious Bat Buyer
You can often get the same or similar bat at lower cost with little extra effort. Here are a few ways to do that:
Bats are at their most expensive in January through April when little league baseball is in full swing. Starting around early May and typically lasting through at least July, prices are reduced to move inventory out, especially in sporting goods stores devoted to multiple sports such as Big 5 or Sports Authority. Look for a similar seasonality pattern with online purchases. The bat my son used in 2015 cost $20, discounted from $70, because it was purchased in late July of 2014. He didn’t use it until he grew large enough to use it 9 months later.
There’s rarely a reason to buy the current year’s model over last year’s model. In most cases, year-over-year improvements are incremental. Getting the prior model may cost 50% of the current year’s model, or even less.
Bat makers warn that composite barrels will not perform as well if stored in hot trunks, used in cold (less than 60 degrees Fahrenheit), or used in batting cages. They are also more expensive and require break-in. In recent years, very light drop 10 to drop 13 aluminum bats also have similar issues as bat makers push the limits on thinness (heavier aluminum bats are more durable). So if you do decide to get an expensive bat, be sure to take good care of the bat so you don’t soon have to replace it.
If your kid likes the feel and sound of aluminum bats and hits well with them, then stick with one-piece aluminum bats. They cost less, and in some cases perform nearly as well as top composite bats on the field. Also, aluminum alloy bats usually have smaller sweet spots and more vibration. This provides more tactile feedback which some people believe helps players improve.
As I’ve repeated many times throughout this article, for kids age 12 or younger, buying an expensive bat only makes sense for a player who consistently hits the ball hard. If your kid is struggling at the plate, a lighter and/or smaller bat may help, but a more expensive bat probably won’t. So don’t buy an expensive bat until your kid consistently hits the ball into play.
Can You Really Hit Every Ball to the Outfield With the Magic Bat?
Of course not. It takes a lot more to be a good hitter than a good bat.
However, I covered a lot of material about hitting, the bat/ball collision, and bat technology. To help synthesize all this information, I will summarize why and how the “magic bat” (Easton Mako) does help.
All youth bats are required to perform at or below BPF of 1.15. This springiness factor of 1.15 is attained by many bats as this 2008 study demonstrates. So there has to be something else going on that can help players hit so many balls into the outfield with the Mako or other high end bats.
A large part of what makes Mako so effective is a bigger, better sweet spot. The larger the sweet spot, the better chance a batter has to hit the ball with the sweet spot. A bigger sweet spot is often, but not always, accompanied by a larger barrel. The youth version of the Mako is only 2 1/4” wide but apparently they have done a great job of making a sweet spot that covers much of the lengthy barrel.
The problem with many bats with long (or big) barrels is that the swing weight increases and it can sometimes be more difficult to swing well. The Mako bat has a light swing weight and is apparently easy to swing. Combine big barrel with easy to swing and you get far more contact with the sweet spot.
As I explained above, the Batted Ball Speed (BBS) will be lower for bats like the Mako that have lower MOI, as compared with high MOI bats of the same length and weight. That means the ball won’t be hit as far. However, that is only true for perfectly hit balls.
Let’s say you’re hitting the ball perfectly on the sweet spot (very far!) once every 20 hits with an end-loaded aluminum bat, and 3 other times you come close for a hit that doesn’t go as far but still makes it to the outfield. You then switch to the Mako and hit it perfectly on the sweet spot half the time you hit the ball and not too badly the other 10 times you hit the ball. You may then feel as if the Mako has more pop because you’re hitting it to the outfield 10 out of 20 hits versus 4 out of 20 for the other bat. However, the perfectly hit ball with the first bat went further because it has a higher swing weight.
So even though the Mako has a lower maximum hit distance, you may not even notice because you are hitting the ball with the sweet spot so much more often and are much happier with the results.
Easton likely also implemented techniques to increase BBS while still satisfying the BPF 1.15 test protocol. The BPF 1.15 protocol is widely considered to be a weak protocol in the sense that there are many ways for bat makers to increase BBS while still satisfying the BPF 1.15 standard, especially with composite bats and/or two-piece designs.
Using a light-swinging bat with a massive sweet spot may improve short-term results. But in my view, the jury is still out as to whether this helps, hinders, or has no effect on developing batter skill in the long run.
Final Words
The batter matters far more than the bat, especially at the youngest ages. Readiness at the plate, a good batting eye, and swinging only at good pitches are all required to get good contact. Good mechanics are also required, though at younger ages some kids are able to hit well despite mechanical issues.
Bats matter very little at the ages of 8 and below. But as kids get older, stronger, and more able to consistently hit the ball hard, higher quality bats make a difference for batted ball speed and likelihood of hitting the sweet spot.
At this point in time, the most expensive composite bats give the batter a greater advantage than less expensive composite bats and even the best one-piece aluminum alloy bats, though it is not clear by how much. The gap between the very best composite bats and the very best aluminum bats has been gradually widening, especially for the light-swinging style of bat, as composite bat makers figure out new and clever ways to increase actual performance on the field while still satisfying the letter of the law, the BPF 1.15 standard.
However, this state of affairs will not last. The goal of creating standards is to base them on scientifically sound measurements of actual performance on the field. Alan Nathan and other baseball scientists do not believe that the current BPF standard used for youth baseball meets this goal. In order to insure pitcher safety, new standards will have to be devised and implemented, and this will reduce the variation in bat performance.
In the end, bat purchasing decisions are a matter of preference, goals, and budget, just like any other purchase. Though a great hitter will hit well with most any bat that isn’t too heavy, some bats will feel more comfortable than others.
Go with the bat that feels most comfortable. It may not be the bat that theoretically hits the ball the farthest, or the one that is currently most popular. But feeling comfortable and ready to hit is a large part of successful hitting. A bat that can help with that is going to mean better results.
Most homeruns in the 2015 little league World Series seem to be coming off the orange Demarini Bat. It seems to have too much pop. I’ve been around youth baseball for years and I have observed practices where this bat is used. For one, the ball contact sound is very distinct, unlike other bats. The ball comes off this bat very powerfully. It reminds me of the composite erase a few years ago. But seeing smaller players hitting towering home runs seems unusual.
Steve – Thanks for your comment. It seems like the color orange is the key 🙂 . In the San Francisco Bay Area, the most popular bat is the Easton Mako, which also happens to be orange, and I do see some big hits with it. However, in my experience the batter matters much more than the bat, and really good pitching can completely shut down a team loaded with $300 bats.
In my research on bats, I found that some bat makers have found tricks to satisfy the regulations while increasing performance. Every few years they redo regulations that limit how hard bats can hit the ball. Youth baseball is about due for another round of changes. From what I learned, they are already in the beginning stages of changing the regulations, but it might take another few years before the next set of regulatory changes is well enough hashed out to go into effect.
Steve,
My son plays for a10u travel team. He is a solid ball player and seems to favor the 30″ 20oz bats. I’m in the market for a new bat for him and I don’t want to break the bank. Any thoughts?
AJ – This is the best time of year to buy baseball bats as July/August/September is when they heavily discount current year models to make way for next year’s models. Bats that start to retail at $300 in September are all the way down to $150 or even less by August (i.e. Voodoo or Mako).
Look at the sections above for 9-10 year olds and 11-12 year olds. Consider what kind of bats your son prefers. End-weighted? Balanced (weight shifted to handle)? Single piece aluminum or two piece? Then you can narrow it down. Make sure it’s a bat he’s comfortable swinging. Ask him if there are any bats he’s tried out from teammates with a feel that he really likes.
You don’t necessarily need to go for the most expensive bats. I’ve seen several really great hitters who do fine with single-piece aluminum bats, which cost less than two-piece or composite bats.
Good Luck!
Just curious why you don’t even bring up the Demarini CF7. I know you said you couldn’t list them all but for a balanced bat the CF7 is the best I have came across and it has received great reviews from others. My 65 llb 11 year old that has 7 + years of experience loves the 28 drop 10.
Scott – The DeMarini CF7 is a good bat and I thought about including it. There were several minor reasons I chose not to:
* I think the Easton Mako (the regular one) and the CF7 are trying to do the same thing.
* In my area, the Mako is vastly more popular than any other bat. I have only seen one kid with the CF7 and unfortunately it was too big for him so not a good test. Given my much greater experience observing Mako bats, I felt more comfortable going with that one.
* I have seen several kids successfully using the VooDoo so I felt like I’d rather highlight that DeMarini bat, which seems to be one of the best 2 piece bats with an aluminum barrel.
Yes – these are minor reasons. But I didn’t want to have a mammoth list with 30 recommendations per age group, as that would be essentially not recommending anything at all. If I possessed both Mako and CF7 in my son’s size, I would love to test them vs each other to see if one is better than the other, or if they are essentially interchangeable.
Has your son tried Mako too? If so, I would love to hear what you have to say about the CF7 vs the Mako.
I do know that at higher age levels, the CF7 is much more popular. If your son loves the CF7 now and is doing great with it, he should continue with it all the way through BBCOR bats in high school (unless he has a big growth spurt and becomes a big burly power hitter – then you might have him experiment with more end-loaded bats).
There is so much helpful information and observation here, I just want to say thanks for everything you’ve covered.
My 13yo player asked for a Torq for Christmas. I did some research and was reluctant to buy. Talked with coaches over the years about different bats but never got a comfortable recommendation. Then I discussed with my player why he wanted the bat ( turns out that he didn’t know the handle twists and doesn’t want that feature ) and then started research on how to choose a bat. Thankfully, google eventually led me here.
Since reading this article, me and my player discussed the main bat design variables, went to demo some bats in the cage, and now we’re working on an approach to satisfy both of us. We’ll probably get a variety of bats to cover the areas that we want to test out. Something like a 31/26 balanced one-piece alloy, and a 32/24 end-weighted one-piece composite.
Thanks for taking the emotion out and helping us make educated purchasing decisions!
Thanks Mark for sharing your experience in trying to find the right bat for your kid. The way you went about it is exactly what I hoped people would do after reading through this guide. Good luck with the new bats!
so many bats out there drives me crazy right now my son is swinging a 32 youth one piece mizuno not a bad bat buy allways looking for that edge he has used the xl3 easton for 3 years what do you think about a bat with that little extra pop we are not loyal to anyone bat but i know he does not like demarini
Jeremy – Yes, it’s overwhelming to choose from so many bats. I tried to explain above what makes a difference between bats, and then in the later sections recommend some bats based on age, skill level, and price points. Read through the section for your son’s age for suggestions on particular bat models.
Hello Joe, I have had the good fortune to get to know a few guys that did a ton of research on LL bats before i sprung for an expensive one. After using a couple easton bats when my son was 7 and 8 we went with a 31/21 combat b4 big barrel for travel at age 9. While he hit great with it, in retrospect it was too big for him. He is big, 5’4, 115 at 12, but not off the charts big like other kids I have seen his age. When we returned to rec ball after i was exhausted from the daddy ball in travel, my best resource recommended we go with a 2011 easton XL1 and i got 2 for games one 30/20 and a 31/21, and a 30/23 woody for practice. I have been very pleased with the performance of the xl1 bats. My mantra to my son is that if you do the work to hit it square on the sweet spot this bat will take the ball 20-30 feet farther than most other bats. It has paid off and despite some obvious mechanical flaws, mainly clearing his hips way early, he has excelled. His swing speed ranges from 48-54 mph with the 31/21 and he has no problem getting around on faster pitchers (60-65 mph) at our level.
In essence i have been very pleased with the xl1 bats and agree with a lot of the content in your article, it is in line with a lot of what I have seen.
Thanks for writing this, Joe. It’s very helpful. I’m about to start a blog about what things are made of – MaterialGyrl.com. I’m a materials engineer and teach a course called Materials in Gear. I came across your very good baseball bat article in a search for misconceptions I could address in class (around the sweet spot in this case). (Can you think of others in your role as a baseball fan?) I’ll be checking back for sure!
Hi Rachel – Good question! But before I get to it . . .
I saw that the domain name for your new blog is not yet registered with anyone. Be sure to register the name of your domain within minutes after you read this. Namecheap.com is one of the better ones to register with. Why? Because once you start telling people about your name, other people (in some cases, automated bots) will quickly register your name. So instead of you getting it for $12/year or so, they will then want you to buy it from them for a few hundred dollars before you can use it.
To your question about misconceptions with baseball bats. There are a ton. I will try to mostly stick just to the ones that have to do with baseball materials.
The biggest is written about in two different posts on my site:
http://www.filterjoe.com/2015/05/13/best-youth-baseball-bats-comprehensive-guide/
http://www.filterjoe.com/2015/06/02/the-bat-with-the-biggest-barrel-and-most-pop/
Did you read the second one? Most of the article is spent discussing what the head of research and development of Axe Bat felt were the two biggest misconceptions about baseball bats by consumers. And both misconceptions are related to materials in bats:
Most people get so excited when a bat has a lot of pop. He’s right. I’ve seen on the field players think one bat has more pop (due to materials) than another, when usually it’s about weight.
It can be that the bat the player was swing was too heavy, so switching to a lighter bat makes it easier to swing and the player than much for frequently hits ball with sweet spot. Or it could be the player has a very slow swing and then moving to a heavier bat still has a slow swing at exactly same speed – and heavier bat hits ball further.
And there are several other reasons – all outlined in that post. The vibration dampening is also discussed there.
Just these 2 topics are enough for quite a lot of discussion as you can see in that article. But there are others.
One that confuses people a bit is MOI (moment of inertia). How the weight is distributed through the bat impacts the swing weight. One-piece aluminum bats have much less flexibility in redistributing weight throughout the bat, as compared with Composite or Two Piece bats, which have more flexibility. And as you likely know, all things being equal, bats with more weight shifted toward the end are going to be harder to swing – but if swung at identical speed (probably won’t happen), the ball will go further.
Thanks Joe! Yes, MOI is another big area of confusion. I spend a whole class period explaining corking and when it does and does not help. I even have some corked bats the students get to try swinging.
Joe,
1st Thanks for this great article! IMO its the most comprehensive review of batting mechanics I’ve seen and I love the fact that its dedicated to the largest baseball demographic in the sport. (Little League)
I cant say I disagree with anything you have put. My son is 7yo and I bought him 2-1/4 LVS its a 30/18 and swings a bit heavy for him but he’s a tall kid and I have him choke hit quite a bit. But I will say that the 2-1/4 did seem to hurt him a bit since this league allows 2-3/4. he was consistently the best contact hitter on on the team but some of the smaller kids with those big barrel bats seemed to drive it a bit better. But I’m with you that the smaller barrel will hopefully pay off in the end.
OK MY QUESTION: Have you had a chance to review the 2016 Combat Maxum bats. These are the highest of the high end and offer a Big Barrel, Huge Sweet Spot but some how still maintain the weight of a smaller barrel bat. i’d like to know your opinion of these bats in particular the -12 and -10 variety?
Thanks again for the article
Matt
Hi Matt,
I appreciate your comment!
I’ve seen just 2 players in my league use a Combat bat (can’t remember if it was a Maxum – but they were 2013 or 2014 models). One player was using a 2 5/8 Combat that was obviously too heavy for him and had trouble getting quality contact with it. The other is one of the top few hitters in his age group and I think it was a 2 1/4 – but I’ve seen him pick up other bats and hit great as well. So that didn’t give me enough information to have much of an opinion about the Combat. So the only advice I could give is all the generic advice I gave above, the most important of which is make sure it isn’t too heavy.
As for 2 1/4 vs fatter barrels – yes no doubt some kids are getting better hits because of the fatter barrel – and likely are developing a sloppier swing as the bat lets you get a way with it. I’ve now seen several instances of players who were top hitters at the ages of 7 and 8 turn into average hitters by a few years later, and I always wonder how much of it was letting them use big barrels at the 7 and 8 age.
Hi, Joe. Do you happen to have any idea what type of aluminum DeMarini’s DX1 is? My 10 year old dented his new DeMarini 30 drop 10 uprising almost immediately. I want to make sure to avoid the same alloy with our next purchase. Or is it simply a matter of any aluminum big barrel drop-10 bat will be prone to denting due to the thinner wall of aluminum? Thanks!
Hi Bill – Knowing the aluminum alloy that goes into a bat doesn’t say anything about how likely the bat is to dent. It’s mostly a function of wall thickness. Very thick walls with any alloy won’t dent. Super thin walls with any alloy will dent. What the better alloys get you is the ability to go thinner without denting, but the bat makers sometimes push too thin even with very high quality alloys, such as a particular Easton model I discussed in the article.
One brand that is much more durable than others is the Axe Bat, with a knob that is shaped like the knob of an axe. They engineer the bat for two primary hitting surfaces (one for left-handed batters, the other for right-handed). When you know which part of the bat a ball is going to hit, it’s possible to engineer the bat for greater durability.
But there are plenty of other durable bats on the market. Most, in fact. The problem is, that you don’t know if you’re going to get one of the ones that dent easily and there’s no easy way to tell (except for Axe Bats for reasons I just stated).
In my experience, the bats which dent most easily are drop 13 or drop 14 bats for T-ball. They’re typically made of low grade Aluminum with very thin walls in order to be light enough for T-ball – but sometimes an older kid or adult uses one and it quickly dents.
Trying to decide on new mako or cf8 for 11 year old? Is either better than other?
Both models are excellent and are somewhat similar in swing feel. I would make the choice based on which has the best weight/length combo. How tall and heavy is your son? Base it on that, and whatever you do get smaller than 32″ length even if your son is very tall. Note that the actual weight of bats, and particularly Mako models in recent years, tends to run 1 to 3 oz overweight compared to what is printed on the bat.
I am managing a team this year and have insisted two of my players use lighter/smaller bats and strongly recommended that a couple other players do so. Anyone who has played baseball for a few years should be able to consistently hit line drives off a tee or with soft toss into a net. If they can’t, then the bat is probably too heavy.
What an informative article! Thanks for your research and insight. I am wondering, if in the course of your research you found any independent labs that compared bats from different manufacturers and different price ranges. I have been frustrated at the seeming lack of information regarding performance. It would seem easy enough with a calibrated robotic arm and pitching machine to come up with some truly objective metrics that would show best bang for your buck bats. Instead it all seems so subjective! We have always been cost conscious in regards to baseball equipment in general. My son used a Louisville Slugger Omaha for two years, it was a fraction of the price of some of the Easton’s and his hitting did not seem to suffer at all. He is now playing in senior league (14-17U). Got a new Mizuno Generation that was well under $100 and he loves it. His exit speeds are right up there with the other kids swinging Mako’s. I don’t discount the adage that you get what you pay for, but I feel there is a price point above which you have a VERY limited return on investment.
Hi Dirk,
I did a ton of research and the only testing I was able to find was:
1) Manufacturers are required to have their bats undergo testing in order to get approved by the various regulatory bodies. These tests, however, merely insure that the bats do not have excessive “pop” and they are not made available to the public.
2) I did see one site that was attempting to do some more in-depth objective testing, with regards to high-school level BBCOR bats. They covered MOI and balance points:
http://topbbcor.net/2015-top-bbcor-bats-by-type-of-hitter/
My own attempt to exhaustively test two bats in real-world conditions produced the following review:
http://www.filterjoe.com/2015/08/06/axe-bat-review-10-year-old/
If you read my review all the way through, you will see that I admit to great difficulty establishing a reasonable methodology.
Let me give you an example of something I see over and over. Kid goes to the best local bat store in the area, which has cages. He swings a few different bats and with one of them he is hitting bomb after bomb after bomb at the batting cage. Great pop, obviously. A no-brainer to get this bat, right?
Buys it. Takes it home. Maybe hits one all the way to the fence with it in batting practice from coach pitches. However, at games, can’t do squat. It’s all strikeouts, foul balls, weak popups, weak grounders etc. What’s happening here?
Sometimes it’s just that the bat is too heavy and/or too long and therefore difficult to control in live game conditions. Or it may be hard to control for other reasons, such as being a two piece bat.
The problem is – under testing conditions it does great, whether theoretically with a machine or with a kid swinging off a tee, soft toss, at the cages, straight-down-the-middle coach pitch, etc. But under real game conditions, pitchers try to make it hard. How much pop the bat has doesn’t matter anywhere near so much as how well the player can control the bat. If 1 of 50 swings results in the bat contacting the ball square on the sweet spot, that is going to give terrible results despite the bat possibly having more pop or a bigger sweet spot or whatever compared to its competitors. A reasonably good hitter can get great results with a too-heavy bat at the cages or off a tee, but then struggles during a game to adjust the bat mid-swing if needed, if the bat is too difficult to control.
I wish there was a test for how well a player can control a bat. I don’t know if such a test can be devised. I can tell you what I did last week as coach: I gave my kids a 5 minute lecture about bats and how important it is to be hitting line drives – and how you can’t do that with a bat that is too heavy/long. I then had every player on the team do soft toss with me. I could see that two players were struggling to consistently hit line drives, and a couple other players were borderline. If you can’t consistently hit line drives during soft toss, there’s no way you’ll be able to do it during the games. With both players – when I insisted they try a teammate’s lighter bat, they could hit line drives consistently.
Both these guys have great bats with great pop that they are not yet big/strong enough to adequately control. However – both do fine with lighter/smaller models. With one guy it was particularly dramatic as he couldn’t hit a ball into play during first 2 scrimmages but during 3rd scrimmage he used a bat that was 2 ounces lighter and smashed bombs to the outfield with every at bat. Probably not as far as he could theoretically hit with his several hundred dollar, heavier bat. But the control is what mattered.
Sorry to be so long-winded, but I get passionate about this topic. In your situation, your son will soon be required to use a BBCOR bat if he wants to play on a high school team. That review site might be very helpful, especially if he is a small kid. Because a small kid will have trouble swinging most regulation BBCOR drop 3 bats. So you’ll want to be sure the MOI is at the low end of the scale for the BBCOR bat you buy. If you didn’t read that part of the above post, search for MOI and read about it as it’s especially important with BBCOR bats since you can’t drop the weight of the bat.
Hope some of this helped – and good luck finding the best bat for your son!
Dirk – I looked at their report again – among the (now last year’s) models they tested, the two BBCOR bats with the lowest MOI were Easton Mako (8843) and Demarini CF7 (8974). For shorter high school players (which will be most Freshman and Sophomores, I would think), these two models would be leading contenders to consider. The RIP-IT Helium wasn’t too bad either at 9,203.
However, it’s not clear how many models they tested. There may be some other models that have even lower MOI, that simply weren’t tested.
Personally, I wish MOI was listed on every bat. Nothing is more objective and helpful to a coach and player as that number.
Hi Joe- my 11 year old son is looking for a new bat for use on his travel team and in LL. You caught my interest with your reference to the Anderson Techzillia above. The CF7 and Marruci Hex Composite are on his short list as well. My son is 5ft tall and about 105lbs, and currently is hitting a 30″ 19oz Marucci Black2. I am thinking it is time to move to a 31″ bat.
I am basically curious about the Anderson bat above, but have reservations about the end loaded component. Especially, since the competition is kicking up a bit this year, as he moved to a new division, and will be on the younger side now.
My son typically hits the ball in the gaps, or back up the middle, but does not pull the ball on a consistent basis. Do you think that the he could be getting into hot water with the heavier -9 Techzilla?
Sorry for all the back story, but I really value your opinion
Hi George – without the backstory I would have no idea what to recommend so no problem with that. 30″ 19oz is fairly light for someone with that height and weight. It’s unlikely he’ll be able to swing that bat any faster. I think you’re better off adding weight than length to the bat, because 31″ is much harder to control and I’ve seen many a 5′ tall kid struggle to hit with a 31″ bat, even a light one. What is his OBP? If his OBP is in the .600 to .800 level in rec league and .400 – .500 level in travel ball, then you’ve definitely got a decent contact hitter and may not want to mess with that formula. If that is the case, a slightly heavier Anderson may be fine, or a CF7 or Mako to achieve similar results (though personally, I love one piece Aluminum and would love to get my hands on a good Anderson for testing!).
However, 105 lbs seems like he is not a skinny stick of a kid like my son (who is 4′ 7″, 69 lbs, and hitting quite like your own son with a 30″ 19oz bat – An Axe Origin which I’ll be posting a very favorable review about in a few weeks). With that kind of height and weight, it can’t hurt to experiment with end loaded – but try a friend’s bat first with a tee and soft toss to see how he handles it. If nobody has a Techzilla around, then borrow an Easton XL1 to see how he handles it as those are fairly end weighted. Could be that he will hit 40′ further with something that weighs a couple ounces more.
Easton Mako bats are heavier than advertised so a drop 10 30″ Easton Mako might be perfect. It’s going to weigh more than the stated 20 oz weight – more like 21 or 22 oz – which is just about right for your son’s height and weight, or will be very soon. It is “balanced” so it will be much easier to swing than a Techzilla.
The big benefit of Techzilla is that if your son is already seriously thinking high school may be in his future, then he’ll start getting used to heavier bat weights. On HS baseball team, even as Freshman, he will have to use a drop 3 bat which is very hard to get used to if he’s been swinging light bats all the way through.
But given what you’ve told me, something like a 30″ Mako or CF7 would probably be the best bet as it will be similar to what he’s used to but the ball will go 30′ to 40′ further if he can keep his swing speed the same, which may be the case given his height and weight.
Thanks for the thorough feedback! I was really thinking that the next logical step was to move to a 31″ bat. It sounds like a better transition would be to a heavier bat in your opinion. I shouldn’t worry too much about the length, eh? I would like to see him toy around with the end loaded bat out of curiosity, and may find someone’s to borrow.
But the 30″/20oz Easton Mako or something similar would be the less dramatic change, right?
Yes. 30″ mako or cf7 would be comfortable. If you can have him experiment with teammates bats with soft toss, that would be a zero risk way to experiment. You are looking to see if he can hit many line drives.
Comments about the 2016 Combat Maxum MAXSL 112 2 5/8″ Drop 12:
I (former pro player) coach a 9-10 year olds competitive team that plays Mustang (Pony) League in Puerto Rico that sports a 36-6 W/L record. I never heard of the Combat composite bat named above, but the team I faced just 2 weeks ago had 3 of these bats, which their coach told me they purchased to replace 3 Easton Makos they had purchased originally. They had several good hitters who swung the lighter Combat Maxums with such impressive ease and “pop”. After seeing those kids’ performance, we are investing in the purchase of a couple of these bats (2-5/8″ dia., 29″/170z.) for about $300 each. We will be participating in the state tournament in late April 2016 and this will allow us to break-in the bats and have the hitters adjust to the balanced weight. Most of our kids, good hitters, currently use bats with drops in the range of -8 (too heavy!) to -10, and lengths in the range of 27 to 30 inches, which they swing notably slower when compared with the kids of similar weight and size we just faced who used the new Combat bat. I would suggest to all in this chat to try the high end composite Combat Maxum -12 if league regulation allows its use.
Otto – Thanks sharing your observations. Drop 8 is going to be too heavy for all but the biggest 10-year-olds (well above 5 feet tall). Also try weighing your Mako bats and you will see they are a couple ounces heavier than stated on the bat. So yes – the Combat Maxum or some other lighter bat will be easier to control and faster swinging and therefore get better results.
By the way, outstanding article with a wealth of knowledge/research-based information on a youth baseball bat subject matter that many coaches and parents need guidance for. Thank you for such well written article!
I coach a 9U team that has a lot of parents that have done their research and so I see a lot of new bats each year, as the parents are trying to get that extra base out of each hit. Some of the bats the boys are using seem too big, but the parent’s insist. So one of my options is to have the kids choke up on a bigger bat (so they can still use the bat their parents swear by), in your opinion, will the kids still get the benefit of using a larger bat even if they choke up? I know they are sacrificing the length but does choking up on a heavier bat still have more benefit then using a lighter bat? Great article, appreciate all your insight.
Scott,
I don’t know the answer to your question, though I suspect it’s complex. For example, some comments from a mechanical engineer who worked on this stuff suggest that the sweet spot moves if you choke up:
hitting a baseball (slugger museum)
Many of these high tech bats are engineered to have a sweet spot have maximum “pop” at a certain part of the bat, so I would wonder if you’re moving off the best spot by choking up. This is just one of several questions I would have about whether choking up is the same as using a smaller bat.
But of more practical consideration is whether you can actually get the kid to do it. I can get kids to use a smaller bat. I can almost never get them to choke up.
By the way, if you haven’t read it, I suspect you’d like my latest post on how to determine whether a kid is swinging a bat that is too heavy:
http://www.filterjoe.com/2016/03/10/is-your-kids-bat-too-heavy-heres-how-to-tell/
Son is 4’7″ 80 lbs 9 year old
More of a Contact hitter but has some power. Line diver or hard ground balls vs towering long deep drives. It’s his 5th year baseball and plays travel.
Using a teammates mako 2015 28/17. He is crushing it. I like the pop he is getting. We’ve only faced avg to slow pitching though.
I weighed the bat and it’s close to 20ozs
The recommendations say his size is a 29″ but based on the makos true weight it’s almost 3oz more than listed.
1.) Any idea how much diff in barrel length in the 2016 mako drop -12 vs -11
2) I was looking at the 29 drop 12 but I’m afraid the extra inch plus 3oz might slow him down. Rather be too short or right on than too long and heavy. Any thoughts?
3) Any diff between the 2015 bat and 2016 mako?
4) Any diff in weight distribution of the drop 12 vs 11 plus any difference in the pop on the sweet spot or is the barrel just a little shorter
5) Any idea if the moi’s on the -11&-12 are the same ?
6) Any recommendations?
Sent from my iPhone
Mike – Most 9-year-olds will struggle using anything more than 20 oz., and even 20 oz will be too much for many. So I would steer away from anything heavier than this model. Unfortunately, Easton is all over the place with their weights. Mako models are over by 1.5 to 3 oz depending on the model, and I unfortunately don’t have enough data to reliably know which ones weigh what. I have seen entire teams outfitted with Mako bats hit poorly against decent pitching, and my guess is that it’s because the Mako bats are too heavy for them to control well (but probably they don’t realize they are too heavy based on what’s printed on the bat).
Yes – an extra inch and extra ounce will almost certainly cause your son’s hitting to decline, most especially against good pitching where he’ll need bat control.
I don’t have enough information to answer most of your questions. I’ve been toying with the idea of becoming a central clearing house for actual bat weights where I ask readers to submit their bat model information along with how much it weighed on a scale.
One company that is much more predictable with its bat weight is Baden with the Axe bat. Every bat is almost exactly 1 ounce over. You could get an Axe Bat Origin 29″ drop 12 and I am confident it will weight very close to 18 oz. That could be a very good bat for your son as it is somewhat end weighted (as opposed to Mako which shifts the weight toward the handle). My review on the Origin Axe Bat:
http://www.filterjoe.com/2016/03/28/axe-bat-origin-review/
My son is 12 (playing 13U) and currently uses as 29/19. The issue is that he is currently on his 3rd bat in 2 months. We had an Easton S3 for about 8 months before it dented. We got a new 2016 S3 and that lasted a whole 4 up to bats and was dented. We then opted to go for a Marucci Hex Alloy hoping it would last longer and that lasted 3 tournaments. He is currently borrowing a 28/20 from a player while we replace this bat, no issues so far and he continues to hit well.
My son is maybe 90 lbs and just over 5 feet. He is a contact hitter, has a fast swing. He has an exceptional batting average and on base average. We don’t really want to switch bat length/weights as next year he will be required to go to -5 anyway. I am curious why his bats don’t last.
Melinda – Easton S3 bats dent easily (particularly the 2014 model), as you can see from reviews around the web. One of my son’s teammates went through two S3’s. Bat makers try to push aluminum bats to be as thin as possible to try to get more pop but sometimes it gets too thin and then they dent easily. Using the bats in extreme temperatures (especially cold) can increase the chance of denting.
Very surprised about the Marucci. First I’ve heard of one of those denting.
Note that you can get bats replaced for free from the manufacturer if they dent after just a few months of use. This is not supposed to happen.
One reason I have come to love Axe Bats lately is that they are engineered for one-sided hitting and therefore are more durable so long as they are used as intended (gripping the knob like an axe). So that might be a nice bat for your son to try if you’re getting tired of going through so many bats.
However, most aluminum bats won’t dent. You were unfortunate to have started with Easton S3 bats.
Joe, this is a great article. I was wondering if you have any thoughts on which drop 8 bats on the market have the lowest MOI? Thanks.
Jerry – MOI is unfortunately not published. I would guess that the DeMarini CF8 would be among the lowest from what I’ve read among various reviews but my son has never tried one so I don’t have first hand experience.
Hey Joe, great read. I thought I had the answer for my son, but I’m not so sure. He will be 10 in Oct. He plays rec and travel league. He is also in private hitting lessons now. I am told he has great mechanics and a great swing. He crushes the ball in a short cage and looks great. When in the game he makes plenty of contact and strikes out very little. He has a mako 28/16, a 29/18, and a one piece combat maxim 28/16( feels much lighter than the mako). My issue is that when he hits the ball for the most part stays in the infield. Some hard hits and some line drives, but mostly weak grounders. The combat is the lightest bat and he has been using that for a faster swing speed. He hit a couple of liners to the outfield at first and now he is back to weak grounders. Some kids have on our team have bad mechanics and are hitting the ball to the outfield consistently . I don’t know what to tell him to do anymore. I can’t figure it out. Any advice would be helpful. Thanks
Chris – I’ve seen this pattern many times. Great bat, decent mechanics, great in the cages. Yet it’s weak hits in actual games.
Most likely it’s bat control. Have him try some one-piece aluminum bats, which many players find easiest to control (see above for my sub $100 one-piece aluminum recommendations – Easton S500 and Axe Bat Origin . . . Marucci also makes great aluminum bats that are pricier).
Soft toss is the most reliable way I’ve found to test bat control – have him borrow a bunch of different bats from teammates and see which one he can hit solid line drives with the most, into the net. It is harder to hit consistent line drives in soft toss than the batting cages, because ball trajectory is less predicable and you have to adjust the bat to where the ball is. See following post I wrote for details:
http://www.filterjoe.com/2016/03/10/is-your-kids-bat-too-heavy-heres-how-to-tell/
If it’s not a matter of bat control, it could be “seeing” the ball. Get his eyes checked if you haven’t recently. Make sure he’s not pulling his head when swinging – need to keep your eye on the ball all the way through until it contacts the bat (this is such common coach advice that I imagine his coaches have already worked with him on this).
Seeing the ball can take many repetitions for some players, while others get it quicker. I have seen several players who hit weak hits literally for years but then suddenly, over the course of a week or two, something magical happens and they start hitting the ball solidly. Just had that happen to a player on my team a few weeks ago and now he’s one of the top contact hitters on the team hitting many solid line drive singles, after years of always being last in the batting order.
How many lessons has he taken? It takes at least 5 lessons before you’ll start noticing a difference, and given that you’re doing it during the season, it could hurt before it helps as he adjusts to the new mechanics. I prefer doing private lessons in the off season for that reason. You might also find this post on hitting lessons helpful:
http://www.filterjoe.com/2015/10/08/do-hitting-mechanics-matter-in-youth-baseball/
Let me know if you have any more questions. These kinds of questions come up a lot, and sometimes take a year or two to work through. If you’re lucky, it may turn around in less than a month from private hitting instruction.
Thanks Joe, he has been getting hitting lessons for a solid year. His combat maxim is a one piece composite. He his line drives into the net all day doing soft toss. The instructor has him stepping into the pitch rather than loading, thinking he was loading too late and no ready to hit when the ball was coming.
Maybe it’s a timing thing, if he doesn’t get hi foot down at the right time. I’m about to give up on lessons and just let him work out of it on his own. Also, I think he needs to build up his strength. Thanks so much , Chris
Sounds like you’ve already tried everything, Chris. At some point it will all come together. So, at this point, just keep his perseverance and confidence up as much as you can. As you hear stories of people who didn’t do much at the plate for years, relay those stories to him.
The top hitter on the rec ball team I coached this year struck out 2/3 of the time last year, after playing baseball for years. This year, at the age of 12, he struck out only once (with one hour left to go in the last game of the season!), and had numerous terrific line drive singles and doubles. Very hard hit balls. I didn’t have him last year but people keep telling me how much he struggled last year . . .
Thanks Joe, I’m sure he will come around.
Hi again Joe! Was impressed by your last answer, so coming to you again. Here is the dilemma…
My son, who will be a HS freshman this fall started using a BBCOR bat (32/29) last fall for fall-ball. He is a big 14U player (6′ and 150#) and really has no problem swinging the BBCOR bat, in fact he just broke 80 mph on his exit speed using the BBCOR bat a few weeks ago. Now for the dilemma…
I really thought that 14U travel baseball required BBCOR bats, but now that our summer tournaments schedule has begun I see most (almost all) kids swinging BPF 1.15 bats. My son is hitting well, but a lot of his hard hit fly balls are being caught in the outfield. I think with the added “pop” of a bpf bat he would be putting them over the outfielders or even over the fence… My son however likes his bat and he points out that he doesn’t want to get used to a lighter swing-weight when his HS baseball workouts will be starting in a few months anyway. What would you suggest?
What is the true performance difference between the two bat types? I KNOW there is a significant difference–just today I was hitting him deep fly balls for practice. I started out with a wood bat, took all my effort to get them out to him. I then switched to his old drop 10, bpf 1.15 bat from two years ago and effortlessly was hitting monster fly balls to him. Surprised myself twice when I hit two of them too long and over the 300′ fence.
Hi Dirk,
I haven’t done a large amount of research on BBCOR bats yet because my son is 11. However, I did learn a few things when doing all the research of this guide. The biggest concept to understand with the BBCOR regulations is that the amount of bat pop is required to be the same as that of an average wood bat. Therefore, for a BBCOR bat whose shape is identical and weight is distributed identically to a wood bat and made of a single material, there should theoretically be no measurable performance difference between a BBCOR bat and a wood bat. Of course, not everything is held equal so BBCOR bats are going to be slightly better than wood bats because of how they’re shaped and how the weight is distributed, and perhaps there’s some whip effects as well as various high tech effects are employed.
BPF 1.15 bats have more flexiblity. Wood bats are around 1.05 in terms of “bat performance factor” so the 1.15 limit means the material in the barrel can have 1.15 (maximum) BPF vs the 1.05 in wood bats, which means, if all else is held equal, 9.5% more pop.
However, many other tricks are employed to make the difference greater than 10%. I haven’t studied BBCOR well enough to know which specific tricks are permitted, and which are not and how the testing protocol is set up in order to prevent going over. But at the simplest level, you know that a good BPF 1.15 bat is going to have at least 9.5% more pop than BBCOR.
Of course, there is also the important matter of minimum weight for a given length. A lighter bat is easier to control, and will therefore more frequently get perfect contact on the best part of the sweet spot.
Personally, I agree with your son. Get used to swinging a heavy BBCOR bat. I would imagine the learning curve is long after years of using lighter bats with more pop. High school performance matters if he wants to do more after high school. I imagine that he’ll be hitting better at the start than teammates who have never used a BBCOR bat.
Joe,
This is by far the most comprehensive article I have ever read regarding choosing the proper bat for a youth player and your observations and suggestions are spot on!
I can answer Dirks question above by sharing both my experiences as a competitive softball player, as well as my experiences coaching my 16 and 13-year-old sons in both rec ball and travel ball.
Before I weigh in on Dirk’s question, here is some information backing what you have already stated. I have owned many bats(both aluminum and composite) for both myself and my boys and I can tell you that the most durable bat I ever owned was a 1995 Demarini Double Wall Distance made from CU-31 aluminum. The very next year the new models were made from C405 material and we’re nowhere near as durable.
I have owned bats from Demarini, Louisville Slugger, Combat, Easton, Worth, Mattingly, and Marucci. The best bat that my boys ever used at the 7/8-year-old pitching machine level and even into their first year of live pitch as a 9 year-old, was a 2005 Louisville Slugger Catalyst 29/16 that I bought used off of eBay. Almost every player on my team used this bat because like you I always called it “The Magic Bat” and 7 and 8 -year-olds buy into the mental aspect that it is special. The reality is that the -13 Drop allowed them to swing the bat more effectively without having barrel head drop. I owned a Demarini F2 that was a -10 29/19 but none of my players were strong enough to swing it.
As I have coached over the years I have seen many kids show up at the ballpark with a bat their parents bought them that was entirely too heavy. The results were like you stated, foul balls, pop ups, and poor contact. So I switched them into one of my bats and gave them greater success.
Most kids cannot handle a -10 or lower drop unless they are just physically bigger and stronger. An example of this is my 13-year-old who is much bigger and stronger than his 16-year-old brother was at the same age. The younger brother started swinging a 31/27 -5 Combat B4 when he was 12. His older brother didn’t do that until he was 14 years old.
This year as an experiment, I bought a 2012 Easton XL1 31/26 for $75 off of eBay to show my son what he could do with an endloaded bat compared to his balanced Combat.
Two weeks ago my son hit a ball over 350′ off of a pitcher that was throwing with some pretty good velocity!
So if I were Dirk, I would try to find my son a -5 endloaded bat. His son would get the benefit of the BBF 1.15 and still not drop too far off of the -3 BBcor that he will be swinging next year.
As for BBcor bats, my 16 year old has used both DeMarini CF4 and CF5, Easton S1, and a Combat B5. The Combat B5 is the only bat that I have ever given more than $150 for and that I didn’t buy used. My son actually prefers the Easton S1 for a couple of reasons. The first reason is that it is a balanced bat, and the second reason is that he just started hitting well with it and had a lot of confidence when using it.
So the best thing for people to do is to experiment with different bats if they have the opportunity to do so. Your information you shared about bat lengths and weights is fantastic. Of course there are exceptions to every rule, and there will always be some kid that falls outside of the norm, but for the most part, kids need to swing the bat that allows them the best blend of bat speed and bat control! Hitting is fun and if they get the right weapon, it can make all of the difference in their confidence which will translate in their performance!
Thanks very much for your fantastic comments, Todd. I especially appreciate your discussion of BBCOR bats, which is something my son won’t be dealing with for a while. Hopefully, I’ll have a lot to say about BBCOR bats 4 years from now!
One thing I’m curious about. With the used bats you’ve purchased over the years, did you ever end up with a dead bat? I’ve always thought it safer to buy new (even if 3 years out-of-date) because you know for sure the bat hasn’t been mistreated or used so much that it’s near the end of it’s useful life.
Also, have all used bats you’ve purchased been legal for play? Some youth bats produced before the 2011 BPF 1.15 standard were “hotter” bats of the sort BPF 1.15 was designed to prevent from being used in play. Most youth leagues require BPF 1.15 bats these days.
My little guy is 8 playing travel what bat do you recommend, he has easton xl 1 and just can’t hit, Any help would be great
Bob – I don’t have enough information about your son’s situation to make a recommendation. However, I can say that Easton XL1 is a heavy, end-loaded bat so there’s a possibility the bat is simply too heavy. I suggest you read my post on how to determine if a bat is too heavy, and then test this bat and others with soft toss as described in that post:
http://www.filterjoe.com/2016/03/10/is-your-kids-bat-too-heavy-heres-how-to-tell/
Thank you for all the great information. My son’s OBP in LL this Spring was .709. He used a 31″ 21oz Mako XL 2 1/4″ barrel. Hits were mostly between the gaps. He will now play in 2 Fall teams. A travel team that will play in USSSA tournaments (10u) and an Elite Little League team (11u) where the leagues in the District will play each other using PONY rules. He just turned 10yo, is 5′ tall weighing 125. Mostly due to soccer, he has speed and power. Using a Zepp, his bat speed at impact measured 74mph. I’m looking for a 2 5/8″ bat that he can use for both teams. Many have recommended the Combat Maxum MAXSL110. However the Elite Little League rules only allow BBCOR composite bats. So it looks like I’ll need to go aluminum. I would appreciate your suggestions. Thanks!
Rod – Mako XL is a great bat in the right hands. Those are some impressive numbers. Could you provide a link to the bat rules? I have never hard of BBCOR being required for younger ages – doesn’t usually start until high school, or in some cases a year or two before that.
There are many good aluminum bats but considering he liked the end-weighted Mako XL, the first I would consider if you’re going aluminum is the Anderson Techzilla. If that’s too heavy or too end-weighted for his taste, I think Marucci and Baden Sports (Axe bat) make very good aluminum bats, while the bigger bat makers like Easton and DeMarini are hit and miss with aluminum as they focus more of their attention on composite bats, so far as I can tell.
Thanks Joe. The Axe bat does intrigue me and we will take a look at it. Here is the link to the rules for our District: http://www.nmvll.org/organizations/1306/documents/146125
I too was surprised about BBCOR for composite. One of the coaches said a BPF composite 2 5/8″ would be acceptable, but the way I read it is 2 1/4″ composites are not allowed and if using a 2 5/8″ composite it must be BBCOR. That is consistent with LL’s Intermediate (50-70) Division and Junior League bat rules (http://www.littleleague.org/learn/equipment/baseballbatinfo/batrules.htm).
Rod – I just looked over the rules which are quite simple (and very surprising!) for 50/70 fields (Intermediate and Juniors):
2 5/8″ are going to be hard to control and swing well for most 11 year olds, which effectively means, as you say – you’ll have to use Aluminum until your kid ages and grows. I’d guess somewhere around 5’7″ or taller would be about the time to consider a drop 3 BBCOR bat, which typically won’t be doable for kids below the age of 13 or so. They may as well have just said they’re banning composite bats (which isn’t all that bad an idea, as it means it reduces the chance of pitcher death to near zero).
Luckily, there are some good aluminum bats out there. If you read the entire article, you’ll see that aluminum bats which are easier to control and are more like the kinds of real wood and/or BBCOR bats a kid will eventually use in high school, if he makes it that far. So in some ways it’s an advantage to train with aluminum bats, as opposed to getting used to using bats that can sometimes help you get a good solid hit on what would have been a mishit on a normal bat (I’m thinking bats like the regular Easton Mako, and the DeMarini CF8).
The Axe Bat Origin is a really nice bat – and given your league’s rules, would be one of the best possible bats to use for 11-year-olds (see my Axe bat review if you haven’t already). Anderson’s Techzilla is also very much worth considering considering your kid’s size and how well he did with Mako XL.
Given the bang for the buck you get with the Axe Bat Origin, I bet that once one player is using it on your son’s team, it will spread quickly to many players on your team using it, given it’s effectiveness compared to most other aluminum bats.
Joe, thank you for this article. It’s fantastic. My son turns 11 this month and for his b-day I was thinking of getting him a new bat. He’s 4’10 and weighs 70 lbs. He’s got good mechanics but isn’t a real strong kid. He plays traveling baseball and is definitely more of a line drive hitter than a power hitter, but he does hope to play HS ball one day. I’m trying to decide between the Easton Mako Composite youth bat (29/17) and the Louisville Slugger SLCT 150 drop 12 with the 5/8 barrel. Both would be 29/17 which seems to work well for him, but I’m not sure about that either. Any recommendation would be appreciated.
Blair – my son is around 65 lbs and 4′ 8″ so you’re asking the right person! At his hight, he might be ready for a 30″ bat, though the advantage of 29″ is that he can swing something a little heavier. The Mako might be doable in the 29/17, but keep in mind that Mako bats are one of the worst offenders for weighing more than what the bat states. It will be more like 19 or 20 oz which may be difficult given his height and body build. Certainly a 30/18 Mako would be out of the question.
Has your son used aluminum bats in recent years? I find that the smaller players need a bat they can control, and aluminum 2 1/4 is easiest to control. I would stay away from a 2 5/8 bat given his size. If you read through the article you’ll see that my favorite two are the Axe Bat Origin and the Easton S500. In my opinion, the Axe Bat Origin is going to be a little more appropriate for travel ball than the S500. The Origin 30/18 is what my son swings, and while he’s by no means the top hitter in the league, he does quite well for his size.
You can read my lengthy Axe Bat review to learn more, and you’ll see that the players who tested it were all close in size to your son.
Joe,
Thanks for your response. I checked out that review and it sounds great for my son. I like the price too 🙂 Thanks again!
Joe here’s an update. I went with the 2016 AXE L131C ELITE (-9) 31″. Went out to the field for some soft toss to compare to the 2015 Easton Mako XL YB15MKX 31″. Although the AXE is heavier, my son was able to hit more balls to LF and they went farther. Most of the Mako hits were to CF. I have a feeling that the Mako XL being an end-loaded bat was the reason. He had his first travel-ball tournament this weekend. In the first 2 games, he went 4-4. Only one hit was to the outfield, the others were through the infield. In the second game, I had him try a 2016 Combat Maxum MAXSL112 (-9) 30″. He went 2-3. His first hit was over the SS. His second hit was the farthest he’s ever hit during a game. Over 250′. I must say, if cost is not an issue and you have a kid that can swing, I would recommend the Combat Maxum. However, for the cost, I am satisfied with the Axe Elite. I even took a couple of swings and the Axe was much more comfortable than a standard knob bat. Since the Axe is heavier, during games I’ll probably have him hit with that first then switch to the Combat when the other team makes their defensive shifts.
Joe,
New baseball mom here, and I know very little about baseball equipment but I’m learning (thanks to your articles!). My son is on his 3rd season and loving it. He seems to have some natural talent and has a powerful looking swing (?) He has some great hits but also his fair share of weak grounders and over 3rd baseline foul balls. We’ve been through a few bats (hand me-downs and Easton octane 29″ 17oz) and oddly he thinks he hits best with this too large 30″ 18oz Rawlings composite bat. I want to get him a new bat for Christmas (preferably soon to hopefully find a good sale) and our LL coach said bat regulations may be changing… Anyway, he’s 7, 50″ and 70lbs. Any recommendations would be greatly appreciated!
Hi Stephanie,
You have a very interesting question embedded in your request for advice. Paraphrased:
Most kids tend to want to switch to a heavier or longer bat before they’re ready. When using a too-heavy bat, you will occasionally hit a big one because you hit the ball square on the sweet spot. The benefit of a too-long bat is getting more plate coverage – meaning that you’ll be more easily able to make contact with pitches on the outside part of the plate – being able to hit these outside pitches is probably why your son prefers to use a bat that is too long for him. But the tradeoff for using a too-heavy and/or too-long bat is that you’ll have poorer control over the bat, and therefore you will only rarely hit the ball with the sweet spot.
I am of the strong opinion that 30″ is too long for nearly all 7 year olds. I have a lot of experience with this as my son insisted he use a very light 30″ bat starting at the age of 8, when he was a little shorter than your son (and he weighed a lot less). His batting average went down and the quality of his hits went way down, and his naturally reasonable hitting mechanics changed for the worse. My son is shorter and lighter than average, and is a good contact hitter. It took him until the age of 11 to be able to use a 30″ bat effectively. Kids of average height and weight will be able to use a 30″ bat by 10 or maybe even 9 years old, but 7 is way too young unless we’re talking about the biggest kid in the league.
Your son is considerably bigger than average (he weighs the same as my son who is 11.5 years old!). So he can swing a bat that is near the upper end of my scale in the 7-8 year old section. A 29″ bat makes sense, that weighs either 17oz or 18oz. Keep in mind that the printed weight on bats is often understated. So if you buy a 29/17 bat it may end up weighing over 18oz, and in some cases as much as 20 oz.
For specific bat recommendations, look in the 7-8 year old section above. They’re all very good. But you can do better than that. You can observe him hitting soft toss into a net, to see with which bat (that he borrows from a teammate) he is best able to consistently hit line drives, as a detail in this post:
How to Tell if Your Bat is Too Heavy
Also one last thing – if regulations are changing soon in your league, your safest bet is to buy a one piece aluminum bat such as the Axe Bat Origin or one of the Marucci models mentioned above. Pure aluminum 2 1/4″ bats are never banned in any league.
Joe,
Thanks for the prompt and thoughtful response. He’s by no means the biggest kid in the league but definitely a stocky guy, with speed not being his biggest asset (when the fielding is good he counts on those power hits to safely make it to first) I was searching for that Axe origin bat and it’s sold out everywhere! (Except in the longer lengths) I’ll be adding a net for the backyard to our list as well!
Stephanie – next year’s Axe bat will be available for purchase later this month.
Good Evening,
First let me say that this is a great article. I was wondering if you would recommend something for me. My son turned 11 last week He is using a Rawlings Mach ??? composite bat that is 30″ drop 10 2 1/4″ diameter. He has had it since fall ball ’15. He is now playing fall ball and will be on a 11u travel team next spring that plays in a more competative league than the team he played for last spring. The new league will allow big barrel bats for 11u and 12 u. He is 4’7 and about XXXlbs. He is a contact hitter and has above average bat speed for his age. Shoujld I move him to a big barrel bat or should he keep using this one? He prefers composite bats but I have observed him using an aluminum bat at a batting cage and he seems to hit more liners.
Hi AJ,
I think you meant to type in the weight of your son, an important piece of information. But even without that information – I have seen players hit well with aluminum and hit well with composite and hit well with a mix of the two (composite handle, aluminum barrel). Though I personally have somewhat of a bias in favor of one-piece aluminum 2 1/4″ bats for good bat control, I think the best thing you can do for your son is have him test many different bats of teammates to see what works best for him. You’re looking for line drives with soft toss into the net, as I describe here:
https://www.filterjoe.com/2016/03/10/is-your-kids-bat-too-heavy-heres-how-to-tell/
Don’t get too caught up in thinking there’s one best bat. There isn’t. Have him test a lot of bats and see what happens.
Thanks Joe. Oh, he weighs about 120 lbs. He has always been a thicker kid.
Thanks Joe.
I left out the weight which I realize is key. My son is actually about 4’9″ and is a hefty 120 lbs. He has beenswinging a 30″ drop 10 composite bat for a year now. Is there a chance that the bat is too light for him? He is often way ahead of off speed pitches since moving up to 11u this fall.
Hi AJ,
Now that I know your son’s weight, I have a few more comments. A big mistake I see many hefty kids make is to start using a 31″ bat. You should do everything you can to talk your kid into sticking with 30″ until he is over 5′ 0″ tall. The goal is to keep control of the bat so it’s easier to deal with changeups and curveballs or even fastballs that have a small amount of tailing action. The adjustments a batter makes happen unconsciously, but those adjustments are harder to make as bat length increases.
As for right now, he can increase the weight of the bat. 120 lbs is plenty heavy to be swinging a drop 8 and it’s quite possible he’ll have identical bat speed with a drop 8 as he did with drop 10. However, be sure to weigh his current bat. If it’s already 21 or 22 oz, you may want to stick with it a while longer. Many modern bat makers routinely sell bats that weight 1 to 3 oz heavier than what is stated on the bat, a practice I wish would be stopped.
The aluminum/composite decision should be left up to him. Whatever he prefers the feel of. As I said previously, I see kids hit well with either, though sometimes kids tend to believe in something strongly, so they feel more confident if they use the bat they believe in more.
Thank you for your comments. I just left the hitting coach and he recommended that we stay with a 30″ bat as well and even recommended to stay at -10. He also stated that I should swich to a better bat (our composite is low end) and get an aluminum bat. He recommended the Marucci Hex or something. He says I will know it because it is green He raves about the old Marucci Cat 5 but they are no longer in production. I believe that we will stick with a 30″ drop 10…. question now is 2 1/4″ vs. big barrel…….. Any tips?
AJ – Marucci makes great aluminum bats. So does Baden (the Axe bats). Yet some players prefer composite. Again – it is really hard to know what to recommend unless I was watching your son hitting balls into a net. If you have a really great baseball sporting goods store with a cage in your area, he could try a bunch of bats that way. Or he could try bats from teammates. I personally think big barrel is a bad idea for 9 and 10 year olds but I have seen many kids try them and some of them have success. My theory is that it enables kids to develop bad habits and still have some success because of the bigger barrel allowing more slop in the swing. So I personally insisted my son use 2 1/4″ Aluminum bats through the age of 11. However, your son is much stockier than my son – despite being the same height as my 11.5 year old son, he weights 40 lbs more. So big barrel is a possibility.
I am going to be soon obtaining and reviewing the 2 5/8 (big barrell) 2017 drop 10 30″ Axe bat, which is going to be the bat my son uses in 2017 at the age of 12 if it works out for him:
https://axebat.com/product/2017-origin-l144e-10/
I have high hopes for it but it will be months before I’ve fully tested it and write a review.
I still think drop 10, 20oz seems light for a 120 lb kid. If it’s big barrel I guess it makes sense, but if you go with 2 1/4″, you could go up to 21 or 22 oz, I would think.
Hi Joe, my son just turned 9 in september and plays on both a club and travel team. In 2016 he had a very successful season. He is 56″ tall and weighs 110 lbs. As he did last year at 9u, he will be playing “up” this coming season at the 10u level for both teams. Last year, he was one of the best hitters on his teams and clearly the best power hitter, with 12 home runs. On several occasions, he was able to hit the ball at or near 200 feet. He swung a used 2014 Mako 29/18 bat that we found at the field..lol. I felt his bat speed was excellent. I wanted to get him a new bat for this season but am agonizing over choosing the right one, fearing I may mess with his swing. I feel like I am biased toward the Mako Beast XL as this seems to be the bat that everyone is raving about for 2017, especially for the “power hitters”…with this in mind, I had planned on getting him the 30/20, but was concerned about going up both 1 inch and 2 ounces…from talking to several people I have gotten two varying responses: one, that at his height and weight a 30/20 should be no sweat at all, and the other being that, its a big jump to go up 1in./2oz. I also wonder if a 29/18 bat last season might have been on the small end for him anyway? I guess it boils down to: if a 30/20 isn’t clearly in his height/weight parameters, do i go with the Beast XL 29/19? or switch to a different bat with maybe a -11 drop? As I said, I just don’t want to mess with a good thing in his swing…
Hi Jeff,
It’s really impossible for me to give perfect advice having never seen your son – and frankly it would be tough even if I had seen him. However, 110 lbs implies he is very solidly built, so I would imagine 30/20 is likely an appropriate size. My 11.5-year-old son is only 78 lbs, 56.5″ and he just moved to a 30/20 bat a month ago and seems to be doing fine with it in the few test sessions we’ve done.
If you’ve read the article above, especially the parts about MOI and swing weight, then you know that not all 30/20 bats are the same. They may not actually weigh the same, and if they are end-loaded they will be harder to swing. So be sure to weigh any new bat you get. Nearly all bats are overweight these days so 21 oz is to be expected, but 23 oz might be too much. I’ve weight several Eastons in the past couple years that are 2 to 3 oz overweight.
I strongly recommend testing bats to see if they’re the right size/weight with soft toss, as I described in:
https://www.filterjoe.com/2016/03/10/is-your-kids-bat-too-heavy-heres-how-to-tell/
When it comes down to it, the bat that will preform the best is the bat that the player is most comfortable with. If you have a young player, in my opinion, as long as you have a fairly new bat that is up to standard, it will compete very closely with almost every other bat on the market. I have been playing ball for sixteen years now and I know that if the ball feels good off the bat then it’s good enough. All the science is good but when it comes down to it we’re talking about a matter of less than 5 feet. If your player is hitting balls shorter than 200 feet, you’re talking about a distance of probably less than 2 feet. Try out as many bats as you can, and the one your kid says he likes the most is the one he will do the best with because hitting is ALL about confidence, not science.
That being said, I have used an enormous amount of bats, and to this day my favorite is the white Louisville Slugger 716.
Joe, thanks so much for the response! I understand perfect advice is near impossible. Playing baseball my whole life, I feel like I should have a better grasp on choosing the right bat for my son, but with so much information and factors to consider these days, it is a daunting task. I went out today and purchased a Mako Beast XL 30/20. The first thing I did was weight the bat as you had touched on. Surprisingly, it came to exactly 1.4 lbs on my home scale. So, I guess that is a plus if I am concerned about the weight jump from 18 to 20 ounces. If I am confident my son can handle the move from 29 to 30 inches, I guess my question is this: do i stick with the Beast XL because my son falls into that “power hitter” category and probably has the strength to handle the bat? Or, do i play it “safe” and go with the regular Mako Beast and go with a 30/19? I’m just wondering if you feel the XL is a better bat than the -11 Beast? If he is on the cusp, is it worth it to stick with the XL? There may not be a precise answer to these questions, but I value your thoughts….and along with this, is switching from the 2015 Orange Mako (29/18) to the XL a difficult adjustment in terms of MOI, going from balanced to end loaded?
Jeff – I tend to be a little biased towards end loaded bats, especially for kids who have aspirations to play baseball in high school, where drop 3 bats are going to be heavy no matter how balanced they are. Using end loaded bats all the way up will make the transition easier for some kids to BBCOR.
But even if I didn’t have this bias, my observation is that the biggest power hitters I’ve seen in my area mostly use end-loaded bats, and I’ve seen them do very well with the XL. The XL model seems to have gone through several changes in the last few years, so I’m not sure if the current ones are as good a the yellow model from a few years back. But it still should be very good for a power hitter.
Will there be an adjustment period? Probably. Don’t count on it being an instant success. But if it isn’t working after a few hundred swings, then perhaps it’s too big too fast.
With your son’s body build, though, I suspect he will do well with it.
Be sure he does as well with live kid pitching as he does at the batting cages. I have seen some players (not built as much like a power hitter as your son) fall in love with an XL for what it could do in the cages or coach pitch batting practice. But then they rarely get good contact during games. That is a frustrating situation you want to avoid.
By the way – do you know about the transition to USAbat standard January 2018? All the bats currently sold will be illegal for rec league play. There’s a few articles about this out there, including my own:
https://www.filterjoe.com/2016/12/05/new-usabat-standard-coming-in-2018-for-youth-baseball-bats/
Joe, again, a million thanks for the quick response and super-valuable advice. I tend to agree with everything you’ve pointed out, and its very reassuring to hear it spelled out as you’ve done. The 6 weeks of winter workouts we are about to embark upon will be a great chance to examine how my son handles and adjusts to the XL and a good foundation for when kid pitching comes into play. As for the USAbat standard, I am aware it goes into effect in January 2018, but as far as I know, USSSA will still be sticking with the 1.15 standard for the immediate future, which is the association that my son’s club team is affiliated with. Thanks again!!
I agree that DeMarini CF7 is the great bat . This nice DeMarini bat may supply them with the extra length they need to put it over the fence more consistently. This end loaded bat really crushes them.
It is a good looking youth bat that is made of sturdy two-piece composite construction. It is another bat that has DeMarini’s very popular d-fusion type handle too. It is not only end loaded to help promote superior MOI but it also has a stiff barrel that really makes your youth player make hard contact when they connect with the ball.
Great article! I’m struggling with what size & weight to get my 10.5 yr old. He is 59″ (4’11”) and 82 lbs and has a slender build. Last year he had a 30/18 balanced bat. It’s Feb now and he will be using the new bat thru spring, summer and fall ball. He wants a Mako. What are you thoughts on size and weight for the new bat. Thanks!
Sheri – you’re not kidding about slender – that’s even more slender than my 4′ 9″, 78 lbs son (about to turn 12). Given his height and weight, a Mako drop 10 or drop 11 could work. If he has teammates with both drop 10 and drop 11, see if he can try out a few swings off a tee to see which he likes better. There are many other good bats out there and my son is, at least initially having a great experience with the big barrel drop 10 Axe bat I mentioned in the article. Do check with your rec league to see if they require 2 1/4″ bats, or if 2 5/8″ bats are allowed, before buying a 2 5/8″ bat. Travel ball almost always allows both.
A word of additional advice – given how much he weighs for his height, I would guess he does not have a lot of upper body strength. Anything he can do to increase upper body strength would help his hitting, probably more than which bat he chooses. So calisthenics like push-ups, pullups, one-handed planks, etc. would help, as would activities that require upper body strength such as climbing. A lot of power comes from the legs/hips but upper body does matter some.
Thank you for the quick response! Upon thinking about it he is more like 84 lbs and is not skinny, just not an ounce of fat. I don’t think he has any upper body strength to speak of though.
His rec league does not allow big barrel. My plan was to get him last years Mako because it was the bat he always wanted but I refused to pay full price for. My options are 30/19 or 31/20 or 30/20 end loaded. He is on the edge of sizes, especially if he may grow an inch or 2. I’m leaning toward the 30/19 so as to not bump him up 2 ounces, especially since people have said that the Makos are often heavier than marked. However he does own a perfectly good 30/18 Combat Maxum. I will at the very least take him to the store to swing a few different bat lengths/weights.
Sheri – Mako tend to weight 2 to 3 ounces over the stated weight (as opposed to average bat which seems to be about 1 ounce over). Therefore, you are right – 30/19 would be the better bat for your son, especially given the lack of upper body strength.
Combat Maxum is a great bat – was he successful with the 30/18 in games? Might be worth sticking with that one for a while – though I guess if you do get a Mako and it’s slightly too heavy at first, he can swing the Maxum until he gets a little stronger. Sometimes kids swing a heavier bat against slower pitchers, and last year’s lighter bat against high velocity pitchers.
Joe,
My son is 11 1/2. y/o he weighs about 125 lbs. He plays travel ball. He currently swings a 29/19 Mako w/ barrel of 2 1/4. I want to move him to a 30/20 Mako. He has aspirations of playing high school and further if possible. Should I go with the 2 1/4 barrel or the 2 5/8 barrel?
Dan – A typical time to transition to 2 5/8 barrel is 11 or 12 years old, so I think you’re thinking along the right lines. You didn’t say how tall he is, but at 125 lbs he ought to be getting used to heavier bats than 20 oz, considering he has high school aspirations. As you likely know, he’ll be swinging a drop 3 BBCOR bat in high school.
My son just turned 12 and is swinging a 30/20, despite only weighing 77 lbs, 4′ 9″ tall (and he’s just started swinging a practice bat that is 30/25). At 125 lbs, I would suggest you look at drop 8, not drop 10. And if he’s over 5′ tall, you might consider 31″ bat instead of 30″.
If your son joins a middle school baseball team, many of those teams insist on BBCOR as early as 7th grade.
To summarize: At 11.5 years old, 125 lbs, time to start getting used to heavier bats.
My son is 8 years old almost 9.
Due to new little league bday rules he is in the minors now.
He’s slightly above average size for his age. I see for a 9 year you recommend a 17 oz bat approximately.
Issue is most non composite balanced true to size bats that are 17 oz are a drop 13 which means 30 inch.
What is your take on an averaged sized 9 year old swinging a 30 17 provided it is true to size?
Hi Scott,
Without knowing the exact height and weight of your son (not to mention his body type and skill level), my advice is going to have to be pretty generic. 30/17 is about the lightest bat I would consider for someone of approximately the size you describe. 29/17 through 29/19 are also possibilities depending again on his body build and how sound his swing mechanics are.
My favorite way to advise kids is to watch them try a few different bats (borrowed from teammates at practice) when hitting soft toss into a net, as I describe in detail here:
https://www.filterjoe.com/2016/03/10/is-your-kids-bat-too-heavy-heres-how-to-tell/
Hi Joe,
What do you think about pitching machines for practice for 5-6 years old kids, my kid is almost 6 years old, usually I pitch to him, but I want to try one, my kid doesn’t have any trouble with his swing, he’s playing 3rd or 4th bat on his team, he is using a 27/20.5 wood bat.
Thanks
Jesus – The exact scenario you describe is not something I’ve personally tried, nor have I discussed with anyone else. I can say that for my own son, he really dislikes tee work. He likes soft toss a little better.
One time I borrowed a JUGS soft toss machine for a couple weeks and he was really into practicing with that around, though I suspect he would have lost interest after the novelty wore off if we actually owned it. So I guess it was a good thing that got him motivated to practice his swing more for a couple weeks, though I doubt it was any better than doing manual soft toss. The one thing that was better though was that it didn’t require a person to do the tossing.
For that age, enjoying the game matters more than anything. A few years from now, if your kid is still really into baseball and wanting to practice his swing, I have an article on how to make use of the various different forms of hitting practice – tee/net, soft toss, cages, etc. See:
https://www.filterjoe.com/2015/07/07/practice-hitting-with-tee-and-net-in-your-back-yard/
and one time we borrowed a the kind of pitching machine
Hi Joe!
Great article with tons of useful information for the baseball parent. My son is playing rec ball in a Cal Ripken league this year and we are quickly learning a lot about ball. He’s struggling to hit consistently and swings late, but even more so I notice that the faster the swings, the more his bat tends to wobble through the air. He is 7, 53″ (tall kid) and 55 pounds. His current bat is a 28/18 and feels more end loaded when I take a swing with it from my limited knowledge. Does this seem like an issue of mechanics or bat size? I’m wondering if we need to work on his style more or if a lighter bat would help him be more consistent.
Hi Kim – Glad you found the article useful. I would need to know more about the bat to have an opinion as to whether it might be part of his issues I’m suspecting it may a big barrel and/or be heavily end-loaded.
Given his height/weight, I would try 28/16 or 29/17 bat size. He may be tall, but at 55 lbs it sounds like he has a skinny body build and it could be that his current bat is a little too heavy. You should try weighing it on a scale – some bats are overweight by 2-3 ounces from what is stated on the bat. If I saw a bat wobbling like that in the hands of a 7 year old, I would immediately suspect that bat is more like 19 or 20 oz and he’s simply not strong enough to swing it. If it is a big barrel (2 5/8″) then that may be the issue right there – I have seen very few kids below the age of 9 able to swing a big barrel, and most 9-year-olds struggle as well with such bats. It’s around 10 years old that I start to see a sizeable number of players able to swing big barrels well.
Given that he is inconsistent at squaring up the bat to the ball, I think he should be trying 2 1/4″ one-piece aluminum bats for now to take potential bat issues out of the equation. Encourage him to try some 2 1/4″ bats of his teammates, including a 29/17 and a 28/16, to see if he can more easily and consistently hit the ball off a tee or during soft toss. You can talk to your coach about it as well.
One little anecdote about big barrel – my son did not swing his first big barrel bat until he was nearly 12 years old. He’s swinging very well with it, but given his small size (4′ 9″, 77 lbs on his 12th birthday), big barrel bats were too big and unwieldy before.
Thanks Joe! You’re right about his build; he’s quite the beanpole. The bat he’s been using is a cheaper model Easton 28/18 2 1/4 barrel. I was able to pick up a Louisville TPX warrior (a few models old) on deep discount for under 20 bucks that’s a 29/16 this morning. I weighed both bats with a precise kitchen scale and they each weigh about half an ounce above the stated weight. He took a few swings with the Louisville and will try it again at practice tonight, but it seems promising. With this bat, I’m able to hear the airflow around the bat during swing, as compared to the Easton his swing is relatively silent. That gives me an indication he’s able to swing this bat with more speed, and hopefully will translate into more consistency and a “meet me halfway” to implementing the proper batting mechanics.
Very informative articles .
Great info for a parent to assist Jr Rookie baseball players.
great article, very helpful. I know the little league bat standard is changing for 2018. Will be lots of new bats bought :(Thanks
I have an original 2007 Anderson Techzilla youth baseball bat. There is a brand NEW one on Amazon (still in the wrapper) which is the same bat as mine. This is considered the best Aluminum bat ever made. Can you tell me what my used bat is worth???
The link to the new one is:
http://www.amazon.com/TechZilla-Youth-Baseball-Bat-Model/dp/B000N206FE
Techzilla double walled aluminum bats are great bats. My son has one. However, the old models got replaced with successor models, the latest being Techzilla 2.0. And now none of these are legal for use in rec ball, due to new USAbat standard. So I doubt they’re worth much any more. I saw Techzilla 2.0 models selling off last year for $99, if my memory serves me correctly, so I would imagine that anything prior to that will be worth much less.
Joe,
I am a new reader of your columns and just subscribed today. I feel like a kid at Disney World with the volumes of amazing articles and discussion threads between you and your readers! My question is, do one piece bats deliver measurably more power than two piece construction bats, as such to offset the dampening of the “sting” experienced in the two piece bats? My son will be 12 this Jan 2019 [currently 5 ft, 103 lbs] and we must use USA bats in his Cal Ripkin league. I am undecided between 2 of the two piece options [the Rawlings Quatro Pro 2019 and the Louisville Slugger Prime 919] and a one piece model [I’m considering the Axe Avenge1, 31/21]. If the one piece has considerably more power [because the energy is not lost in the two piece’s “connection” part], then I’m inclined to go with the one piece. Each of these 3 bats is a composite . Thanks, Jim from New Hampshire.
Jim – I would answer this question differently for USSSA than I would for USAbat. Since USAbat is required, I will simply say that in 2018, the better performing models were all single-piece aluminum. Jury is still out on the 2019 models and I have seen and heard nothing so far. But given how poorly composite and/or two-piece models for USAbat performed with 2018 models, I would suggest you stick with single piece aluminum until consensus emerges around one or more models that include composite materials.
The Axe Single piece aluminum models are good. Louisville Slugger Solo 618 was good and I’d assume 619 will also be good. The Rawlings 5150 also has its fans. Those are the first models I would consider.
If you’re really stuck on a composite or two-piece model – perhaps you could find a high end baseball bat store where they have cages and you can have your son try out some of the bat models. He could also maybe borrow a teammate with a model he’s interested in to take a few hundred swings.
Follow up to my Oct 7 query, Joe. Are you aware of any single piece USA bats with effective vibration technology? I like the potential extra power from a one piece, which would be even more appealing if a one piece had some ability to mitigate “the sting.” I’m trying to persuade My soon to be 12 year old son to switch away from the two piece. Thanks, Jim
Jim – My understanding is that the two biggest impacts on vibration in single-piece aluminum bats is the quality/design of the endcap, and the size of the sweet spot (which in many cases is a consequence of the endcap design). Axe bats are a special case because the knob design allows them to have what the call one-sided hitting (it’s really two sides – one for lefty hitters, the other for righty hitters) – which allows them to distribute the bat weight differently than other manufacturers. The tape used around the handle can also have in impact, but my impression is that it is minor.
The Louisville Slugger Solo line has particularly good end-cap design, and so that likely translates into less vibration than most other single-piece aluminum bats. My son has tested a lot of Axe bats and reports to me less vibration than other single-piece aluminum bats.
There will still be some vibration on mishits no matter how good the end caps or other design features. In my mind, vibrational feedback is a GOOD thing – as it’s a good way for batters to get feedback. If the ball is hit by the sweet spot, there will be no vibration.
Thanks, Joe [again]. I’ve narrowed my choice to 1) Louisville 618 [2018 or 2019] or 2) Axe Avenge One [2019], which is 100% composite. It remains to be seen if the 2019 all-composites will out perform the 2018 composites. If not, then single piece aluminum it will be [with considerable $avings].
Hi Jim B – I just restored all the comments of the site, which caused all comments in the past week to be lost – including your comment that alerted me to the missing comments. For the record, here is what you wrote:
Joe, what happened to all of the comments in most of your articles? I periodically double back to see if there’s any comments about the new 2019 USA bats [mainly to see if the 2019 composites are any better than the 2018 composites]. Thanks, Jim
Hello Joe-
My Son is going to be playing in a 11u travel league this spring. He’s currently 10 but will be 11 in early May. He’s 105 lbs and 56″ tall and will be able to swing a USSSA bat with a max barrel dia. of 2 5/8″. I’m stuck between a 30 drop 10 or a 29 drop 8. My thought process is he’ll have better control with the shorter bat and will benefit with the larger MOI. What are your thoughts???
Tom – Better bat control is a potential reason for sticking with 29″, but MOI is not necessarily a legitimate reason. MOI increases with bat length, all else being equal. Of course, MOI increases with weight as well (all else being equal). So without doing the exact measurement, you don’t actually know which bat has the higher MOI.
Both are reasonable to consider for a player this height, weight, and age. My feeling is that the best way to make this decision is to have him try out both bats before deciding which to buy – or if he can’t get hold of the two exact models you’re considering, at least something close. A hundred swings each off soft toss or front toss will be enough for your son to get a good sense of which he prefers.
thanks for the information
My son is about to turn 11, he is 4ft 5.5 inches and weighs 70lbs but he hits some of the farthest hits on the team even though he is a small kid. The most important part is his swing point blank. The composite bats help but its all about the mechanics, staying short, getting behind the ball and being able to make adjustments at the plate. If you are willing to spend alot of cash on a composite bat then also spend some money on hitting lessons . Find an instructor who has had major league experience if possible, if not then minors experience at a minimum. My son is small and once he learned the correct way to hit it was amazing. We do the same stuff at home that he has learned from the hitting instructor. A good instructor can also help you with the correct bat length and weight, too many people think bigger is better. My son swings a rude american moab bat, its there speed bat which is balanced and not top loaded. It is a 29/19 bat but he has a spacer on it so it really is 28inches long with that on. He also works out and plays 4 sports which i believe has alot to do.with how good he is at such a small size. I read all your blogs last night and today, really appreciate the info and honesty, i know what its like to have a small child, its not easy but i cut him no slack, he can never use his size as an excuse, its all about hard work, practice and most importantly desire. My son use to do 8 sports, no lie and when he wanted to stop playing one i let him, it is HIS CHOICE. To many parents force their kids to play sports they dont want to and thats where the desire part comes in, they have to want to play, to practice, to work out, to take lessons, that is the most important thing. Having a bat with alot of pop doesnt mean anything if a player doesnt swing properly, if the bat is to heavy and if the child really doesn’t want to play. Thanks again for the articles!!!!
My son have an Easton brand big barrel bat. The sound that the bat makes when it makes contact is what my son finds so appealing about it.
