Bat Benefits

If you want to experience the hype of Marucci CAT bats, but need it to be legal for use in a USA Baseball league, then this Marucci CAT USA Bat is the one for you. Marucci builds it in a one-piece and all-alloy design. As well, they have specifically employed their AZ105 alloy material that will be knocking baseballs all over USA ballfields.

Marucci doesn't stop there with this bat. They have also made sure that the bat has a multi-variable wall design that expands the sweetspot of the bat and also allows the bat to be more forgiving in its feel (even if you don't square up a pitch perfectly). 

Overall, it should be pretty easy to select this bat if you want something lightweight, high-performing, and USA Baseball-certified all at the same time!


Marucci does their best to make sure that their bats last. And if a case comes up where a bat breaks down, Marucci is most times able to get the customer a replacement under their manufacturer’s warranty period. They offer a twelve (12) month warranty on their bats and that period extends from the date of purchase. If you have bought this bat from us and it has broken down on you within a year from the purchase date, please message our JustBats Bat Experts. The Experts are trained in bat warranty knowledge and will be able to get you the information needed to begin the warranty replacement process with Marucci.

First impressions CT Coach

Pros: Purchased the 32” drop 5 for my 12u grandsons Allstars tournament. Got the bat today. My grandson plays travel ball as well and has a 32” drop 5 Easton Encore Hybrid. This bay feels just like it. End weighted solid feel and good pop. Definitely a decent USA bat for the price.

Cons: None yet.

What is the true barrel size of the Marucci CAT USA bat? I've heard 2 1/2" and 2 5/8". John
The Marucci CAT -5 USA Baseball Bat: MSBC5YUSA features a 2 5/8" barrel diameter.
Is this bat legal for 7-8th grade baseball? steve
As long as the league does not require BBCOR bats the Marucci CAT -5 USA Baseball Bat: MSBC5YUSA would be legal.
My son wants a quiet bat, not a loud ping like a lot of other brands. Is this a good bat for that? steve
An alloy barrel bat, like this Marucci CAT -5 USA Baseball Bat: MSBC5YUSA, will have a louder sound on contact. Would recommend a composite barrel bat if your player prefers a quieter sounding option.
