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.

Perfect bat for:

High school and youth hitters who want a durable one-piece alloy with a dampened knob.

The Marucci CAT9 is a one-piece AZR alloy bat with an AV2 knob. The AV2 anti-vibration knob dampens sting on off-center contact. A multi-variable wall and ring-free barrel widen the sweet spot. It is the CAT generation before the CATX, on the same AZR alloy. It suits hitters who want a durable one-piece alloy across three certs.
