The 2021 Marucci CAT9 Alloy is a USSSA-certified (-10) baseball bat designed for players using the Kid Pitch format, typically ages 9 to 13. Its 28-inch length combined with an 18-ounce weight offers a balanced swing speed and power suited for this age group. The 2 3/4-inch alloy barrel provides durability and consistent performance at the plate, making it suitable for players seeking a reliable bat that meets USSSA standards. This version focuses on an alloy build, which generally delivers a solid, sturdy feel with less vibration on contact. The bat is used, reflecting normal wear but maintains structural integrity. This bat fits players transitioning to more competitive play, offering a manageable drop weight that aids in developing swing mechanics without sacrificing control. Ideal for young hitters who want a bat that delivers balanced weight distribution and certified gameplay performance.

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.
