2021 Marucci CAT9 Alloy USSSA Certified Bat (-10) 20 oz 30" (Used)

The 2021 Marucci CAT9 Alloy is a USSSA-certified youth baseball bat designed for players aged 9 to 13 in kid-pitch leagues. Its 30-inch length and 20-ounce weight result in a -10 drop, a typical balance of swing speed and power for this age group. The 2 3/4-inch barrel made from alloy offers durability and consistent performance with a solid feel at contact. This model is suited for hitters developing their swing mechanics who need a reliable bat to meet USSSA standards. The black finish is standard, with no impact on performance. This used bat’s specifications make it a practical choice for young players transitioning toward more competitive play.

The Marucci CAT 9 features a single piece of aluminum with multivariable wall thickness, extending the sweet spot and reducing swing weight. The CAT9 features a Ring-free barrel which allows for more flex within the barrel and minimizes dead spots through the bat. This model includes new technologies like the AV2 knob to dampen sting on mishits and is available in BBCOR, USSSA, and USA versions.

“

My son really likes the CAT9. He likes the weight distribution and how it feels when he catches it clean with his “A” swing. He also feels like there’s a margin for error on his “B/C” swings. It’s his first BBCOR, which has helped make the transition to the big field manageable.
