Guardian Baseball takes you inside the new 2021 Marucci baseball bat to see what all the hype is about and if the technology is next level. 

2021 Marcucci Cat 9 Technology

The 2021 Marucci Cat 9 Connect BBCOR baseball bat begins with an AZR alloy barrel that utilizes a unique three-stage thermal treatment process. This gives the barrel of the bat a more responsive microstructure to improve feel and forgiveness as well as giving it an additional boost to performance.

The thickest section of the barrel wall features Marucci’s Longitudinal Groove System which reduces weight and increases flexibility for a larger performance zone. You can feel it when you hit your first ball.

The thinner barrel walls and a variable walla design give you a good sized sweet spot and protects performance if you make off-center contact.

The ring-free barrel construction allows for more barrel flex and increases performance with no “dead” spots. In addition to that, the barrel is power-loaded for higher MOI and an end-loaded feel to help you produce more power with less effort. 

Marucci then uses their one-of-a-kind Outer-Locking System to combine the alloy barrel with the composite handle from the outside-in. This system creates the stiffest connection possible and eliminates vibrations in the hand at impact, which makes your swing a lot more enjoyable.

The shape of the handle on the Cat 9 Connect baseball bat is inspired by professional bats. Removable taper and an ergonomic knob shape allow for more control with the top hand and comfort on the bottom. A micro-perforated soft-touch group features extra tack for improved feel and greater control.
