The most popular USSSA bat in the 27, 28, and 29-inch drop 10 space is Marucci’s CAT 9. Although a single piece bat—and a bit more likely to ring the hands—we found pitch speeds slow enough in the 8-year-old leagues that hand sting doesn’t matter. And the Cat 8’s well-built barrel and knob technology to help dampen sting remove any issue anyways.
But the CAT 9 isn’t our favorite bat for 8-year-olds because of the F5. The F5 is the CAT 9 without the fanfare and some tech in the barrel and knob. But, since pitch speeds and swing speeds aren’t peaking at age 8, and it’s more about just finding the ball, we find the F5 to do just as well as the CAT 9 at a fraction of the price.
In August of 2019 we began testing most of the 2020 bats. That data collection process, while ongoing throughout the 2020 season, is now incorporated into the results you see here.

Want all the power, performance, and barrel size of the CAT 9 at a fraction of the price? Then the Marucci F5 is your ticket out of bat buying research mode. For an 8-year-old, we like this bat best because the pitch and swing speeds are not yet high enough to engage the barrel–so any tech that adds extra pop because of the bounce in the barrel becomes ineffective. We think the F5 is the best bat for an 8-year-old. You get the right swing weight, barrel size, and feel, all for a much more reasonable price point.

Need a cheap and straightforward bat for an 8-year-old? Great, get the Vapor from Slugger. It has been around inexpensive, simple, good barrel forever, and it works just fine. No 8-year-old is going to be able to tell the difference. If it’s a rec league bat then this will work great.
Certification: Fastpitch
Sizes: 27, 28, 29, 30, 31

Don’t overthink this one, although you may be tempted. In the end, you need a very light swinging bat that works and feels good. That’s the DIVA. It’s a fastpitch bat, and there’s no such thing as pop for an 8-year-old fastpitch player. We are trying to make contact here, and the DIVA makes that possible with its light swing. More than likely the 27 in the drop 11.5 will do just fine.

If you are in a league that requires a USA Bat for your 8-year-old, we like to keep it simple. We need a light swing, good barrel, and reasonable price point on a bat that will last. Enter the Solo from slugger. Slugger’s USA Solo has been a rock star since its inception in 2018, which continues to this day. Especially for younger players whose pitch speed doesn’t engage the barrel, we find a good barrel, light swing, and a decent feel are all needed. The Solo has proven it’s a go-to in the space and is our recommended bat for 8-year-olds in the USA.

You can’t go wrong with the CAT 9 in JBB. It performs great, gets excellent ratings, has a huge barrel, and feels great. We think the F5 is the smarter buy, as the bat performs just as well as the CAT 9 and pitch speeds don’t engage the barrel enough to see any differences, but if you want to get what most consider the ‘best’ small JBB type bat, then the Marucci CAT 9 is the pick.

We hit every bat we rate. Most of our hits come from players who might use the bat in a game. Over the past 5 years, we have swung every performance bat made by every serious manufacturer. Also, track the exit speeds, measure the barrel sizes and collect reader feedback about bats. We don’t sell bats and aren’t interested in doing so. We are an independent bat review site out to #spitonthehype, as we like to say.
After surveying over 200 parents of 8-year-old players, we found that the proper bat size for an 8-year-old is, on average, 28 inches and 18 ounces (28/18). The second most common is 29-inches and 19 ounces, followed very closely by a 27/17. We suggest the right size bat for most 8U players to be a 28/18. The chart below shows the 8U market in more detail. (Click here for more information on the chart).
Much like all the other ages we surveyed for the proper bat size, we found that attributes like height, weight, strength, and skill didn’t predict bat size for 8-year-olds very well. In other words, bat fitting in the traditional height/weight chart seems otherwise pointless. Most hitters choose what everyone else in their age group has chosen. For the 8-year-old bunch that coalesces around a 27 – 29-inch bat weighing 17 to 19 ounces. When in doubt, we suggest you go with the 27/17. If you’ve played before, then go with a 28/18. We’d only recommend a 29/19 for those who really know what they are doing and have tried the bat out before.
Also, in the 8-year-old world, drop 11 and drop 12’s work well too. (Drops are the numerical difference between the length of the bat in inches and the bat’s weight in ounces. So, for example, a 28-inch drop of 10 bats has a stated weight of 18 ounces). We mention a few of our favorite drop 11 and drop 12 bats below.
