2021 Marucci CAT9 Composite BBCOR Certified Bat (-3) 29 oz 32" (Used)

The 2021 Marucci CAT9 Composite BBCOR bat is a 32-inch, 29-ounce bat built with a composite barrel designed to provide a balanced feel with a responsive pop. Its 2 5/8-inch barrel diameter and BBCOR certification make it suitable for high school and college play, meeting the standard drop of -3 for competitive regulations. The composite material combines durability with a slightly lighter swing weight compared to traditional aluminum, which can help with increased bat speed and control. This bat is used but maintains solid performance characteristics typical of Marucci’s CAT series. This bat is best suited for advanced high school or college hitters who want a balanced bat that supports quick swing mechanics while still delivering consistent power. Its composite construction helps reduce vibrations on off-center hits, making it a practical choice for players looking to improve contact quality and overall bat control at the plate.

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.
