Bat Benefits

Marucci has outfitted this bat with some impressive advancements. First off, there is new AZR Alloy on the bat. This alloy has undergone a 3-stage thermal treatment process. Because of that process, the new alloy should deliver the trifecta of (1) Better Feel (2) More Forgiveness & (3) More Performance. In addition, the AZR material should still display that same impressive strength that we have come to expect from CAT bats. Next, you'll want to take notice of the Longitudinal Groove System (LGS) that removes extra weight from the thickest part of the barrel and then allows that barrel to flex a little bit. This LGS system ultimately bumps up the performance of the ball off the bat. 

Overall, these two new features are wrapped up in the one-piece, all-alloy design of the CAT bats that so many players have come to love. And don't forget about the sleek, black color.


Marucci offers a twelve (12) month manufacturer's warranty on the bat. If you purchase the bat from JustBats and sense that something is wrong with the bat within 12 months from the purchase, please reach out to our Bat Experts. They can be reached on PHONE at 1-866-321-2287, EMAIL at and CHAT by clicking into the chat box in the bottom right corner of this page. They will be able to get you set up with the info and materials to send the bat to Marucci for a replacement bat!

How much of an improvement will this be over CAT 8 or is it more cosmetic change only?
Coach Brad
Since the Marucci CAT 9 BBCOR Baseball Bat: MCBC9 has not been released yet, it is impossible to say how consumers will rate this bat in comparison to the CAT 8. With that being said, the major change to this bat is the AZR alloy - undergoes a 3-stage thermal treatment process. This creates a more responsive microstructure that results in a better feel, more forgiveness & more performance.
You're saying more performance with the CAT 9. But how much performance can it have if it is restricted BBCOR standard? Would this bat be more balanced than the 2020 5150?
Marucci is marketing the Marucci CAT 9 BBCOR Baseball Bat: MCBC9 has having a more responsive barrel but would not imagine the performance will change dramatically compared to what they have released in the past. As far as how the bat will rate, in terms of balanced swing weight, compared to the Rawlings 5150, it would be hard to say.
Is it good to use and how long can the bat last without breaking?
Michael Gutierrez
The Marucci CAT 9 BBCOR Baseball Bat: MCBC9 is a great BBCOR bat to consider. How long it might last a player before denting would be hard to say as there are too many factors that can play a part with regards to the longevity of a BBCOR bat.
Do you make this bat in a 29/26?
