The 2021 Marucci CAT9 Composite is a USSSA certified youth baseball bat designed for players in the 9 to 13-year-old range, primarily suited for kid-pitch leagues. Featuring a 28-inch length and a 2 3/4-inch barrel, it offers a balanced feel and solid contact surface for hitters developing their swing mechanics. The composite material helps reduce vibration on mis-hits, providing a smoother response through the zone. With a -10 drop weight ratio, it balances swing speed and power, making it accessible for younger players working on bat control and quickness. This bat is used but remains a reliable option for competitive youth players looking to improve their performance with a league-approved model.

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.
