Marucci Cat9 composite bat 28", great condition. used for 1 travel ball season and my son outgrew it. Solid all around bat! Cat 9 Composite baseball bat comes with the MDX composite material on the barrel. The layers of MDX composite are placed in differing patterns to allow for a very responsive barrel. In addition, one thing that will certainly grab the attention of players and parents is the OLS (Outer-Locking System) Connection Point that attaches the handle and barrel from the outside-in. This OLS Connection creates one of the stiffest two-piece bats out there and also diminishes vibration. This Cat 9 composite will truly be a comfortable bat to swing.

Perfect bat for:

Players who see a lot of games, high pitch speeds, and who don’t mind a barrel-heavy bat.

The Marucci CAT 9 Composite bat is a two-piece composite bat found in USSSA, USA, and BBCOR. Unlike its alloy counterparts within the CAT series, the CAT 9 Composite provides a massive barrel and balanced swing. The connection piece helps absorb mishit balls’ sting and is identical to the one used on the BBCOR CAT 8 Connect.

“

The CAT9 Composite comes in two designs across two generations. The first, released in 2021, is gray, black, and red. And then it came out in red, white, blue, and gray. The first model was a more powerful, higher-performing bat. It has more exit velocity and is a hotter bat than the 2nd gen. Very durable, with very little breakage. Marucci's, across the board, have been good bats in terms of quality; they seem to last. Whether you're a power hitter or a small kid, the CAT9 Composite does very well.
