Marucci CAT9 Alloy Bat (Used)

The Marucci CAT9 Alloy is a USSSA-certified youth baseball bat designed for players aged 9 to 13 in the kid pitch division. Its 31-inch length combined with a -10 drop weight ratio (21 oz) strikes a balance between control and swing speed, making it suitable for developing players. The 2 3/4-inch barrel provides a consistent sweet spot, and the alloy construction offers a durable, solid feel at the plate. This 2021 model is used but remains a reliable option for youth players transitioning to more competitive play. This bat works well for players who have begun to refine their swing and want a lightweight, responsive bat that can help generate better bat speed and contact. The size and drop make it appropriate for intermediate skill levels seeking a bat that supports power without sacrificing control. It’s best suited for players in kid pitch leagues aiming to improve their timing and power development.

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.
