The 2021 Marucci CAT9 Composite is a USSSA certified youth baseball bat designed to offer a balanced blend of power and control. Its 32-inch length with a -5 drop makes it suitable for players needing a manageable swing weight, while the 2 3/4" barrel provides a solid sweet spot for consistent contact. The composite material helps reduce vibration on mishits and delivers a responsive feel at the plate. This bat is used but remains a reliable option for youth competition. Ideal for competitive kid pitch players aged 9 to 13, the CAT9 Composite supports developing hitters looking for a lightweight bat that still generates ample pop. The -5 drop helps build swing speed while maintaining control, making it a practical choice for players transitioning toward more advanced bats. Its USSSA certification means it’s approved for most youth leagues following that standard.

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.
