Marucci CAT 9 -5 USSSA Baseball Bat: MSBC95

This CAT 9 drop 5 bat continues the excellence that was started by the original Marucci CAT 5 so many years back! It still features the classic one-piece, all-alloy design!

Bat Benefits

The big advancement from the CAT bats of the past to this CAT 9 is the new AZR Alloy Material. What makes the AZR alloy unique is that it goes through a 3-stage thermal treatment process. After that process is completed, Marucci is left with an aluminum material that (1) has more feel (2) has more forgiveness and (3) performs better. 

That new alloy material is part of the one-piece, all-alloy design that is painted in a black colorway with red & silver graphics!


Marucci covers this bat for twelve (12) months from the purchase date. If you buy the bat from JustBats and the bat breaks down or is not performing, please reach out to the Bat Experts. They can be reached on PHONES at 1-866-321-2287, on EMAIL at or on CHAT by clicking on the chat icon in the bottom right corner of this page. They will be able to assist in getting you set up with the directions and info for sending the bat to Marucci for a replacement.

What is the main difference between this bat and the Cat 8?
Charles C.
This Marucci CAT 9 -5 USSSA Baseball Bat: MSBC95 will feature a new AZR Alloy, it goes through a 3-stage thermal treatment process which makes this material create better feel, better forgiveness and better performance while maintaining the same strength of material seen in past Cat bats.
I would like to know why this bat has 2 3/4 barrel diameter? My son has always used Marucci and he is waiting for this one, other brands have the same specifications bat in 2 5/8, is this going to be a disadvantage to my son?
USSSA allows bat manufacturers to make bats with a max barrel diameter of 2 3/4 inches and so that is what Marucci chose to do with the Marucci CAT 9 -5 USSSA Baseball Bat: MSBC95. Having the larger 2 3/4" barrel diameter, compared to the slightly smaller 2 5/8", gives the hitter a greater chance of squaring the ball up. Getting a bat with the smaller 2 5/8" though would help the hitter get use to what will be used in high school and the BBCOR bats.
Does this bat have a lot of end-load? Or is it a light swinging drop 5?
The Marucci CAT 9 -5 USSSA Baseball Bat: MSBC95 features a balanced swing weight. How this bat relates to other USSSA -5 models in terms of swing weight feel would be hard to say but it will certainly not feel end-loaded.
Is this the same as the cat 9 connect?
CJ Miller
No this Marucci CAT 9 -5 USSSA Baseball Bat: MSBC95 is a one-piece aluminum bat, while the CAT Connect is a two-piece hybrid (Aluminum barrel, composite handle).
