This is a 2021 Marucci CAT9 Composite baseball bat, BBCOR certified for high school and college play. The bat measures 34 inches in length, weighs 31 ounces, and features the standard -3 drop. Its barrel is 2 5/8 inches in diameter, made of composite material, and comes in red, white, and blue colors. I used this bat for one season, and it remains in good shape with normal signs of use. It is suitable for players looking for a reliable BBCOR certified bat for competitive play.

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.
