2021 Marucci Composite Cat 9 composite in hard to find 29" drop -8 size (21oz). Used for Fall season but in good condition with no cracks. The size of the barrel is unmatched in the USSSA space and is HOT!!! Son is moving to drop -5 so looking to upgrade. We have used the CF, Meta, ADV and the Cat 9 Composite has been the BEST bat in USSSA. Baseball Bat Bros also confirms this in the link below: https://www.youtube.com/watch?v=2uA2ktUWGKE&t=10s

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.
