2021 Marucci CAT9 Composite BBCOR Certified Bat (-3) 28 oz 31" (Used)

The 2021 Marucci CAT9 Composite is a BBCOR-certified baseball bat designed for high school and college play, delivering a balanced blend of durability and performance. Its full composite construction provides a larger sweet spot and a more consistent feel on contact, while the -3 drop weight ratio (31 inches long, 28 ounces) offers a well-balanced swing weight that supports quick bat speed without sacrificing control. The red, white, and blue color scheme is distinct, but the focus remains on its performance attributes. This used bat maintains the structural integrity important for competitive play. This bat is suited for high school and college players who need a BBCOR-approved model that supports a quicker, controlled swing. The -3 drop makes it appropriate for players valuing a balanced feel between speed and power. Its composite design helps reduce vibration from mishits, making it a solid choice for hitters who face fast pitching and want a reliable, consistent 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.
