2021 Marucci CAT9 Alloy USSSA Certified Bat (-10) 21 oz 31" (Used)

The 2021 Marucci CAT9 Alloy is a USSSA-certified youth baseball bat designed for kid pitch leagues. Featuring a 31-inch length and a -10 drop, this alloy bat strikes a balance between manageable weight and good swing speed potential. Its 2 3/4-inch barrel offers a solid sweet spot to help with consistent contact, while the alloy construction provides durability and a responsive feel on contact. The navy finish is standard for this model. This bat is used but maintains functional performance. This CAT9 Alloy model fits players aged 9 to 13 who are moving into kid pitch play and need a bat that supports developing power without sacrificing control. The -10 drop weight allows players to generate quicker swings, aiding in timing and bat speed, making it suitable for intermediate skill levels. Its USSSA certification ensures it’s compliant with most youth baseball leagues.

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.
