CAT8 Junior Big Barrel -10

The CAT8 Junior Big Barrel is a USSSA certified, one-piece alloy bat built with AZ105 super strength aluminum alloy meaning thinner walls, higher response rate, and better durability. The precision-balanced barrel features a ring-free multi-variable wall design that creates an expanded sweet spot, while the patented AV2 Anti-Vibration knob produces a better feel and less negative feedback.

One-Piece Alloy Construction: clean, consistent, traditional swing feel
Precision Balanced Barrel: produces a lower M.O.I. for precision and control

2nd Generation AV2 Anti-Vibration Knob: an upgraded, finely tuned harmonic dampening system for better feel and less negative vibrational feedback
AZ105 Alloy: allows for thinner barrel walls, a higher response rate and better durability
Multi-Variable Wall Design: expanded sweet spot and thinner walls for more forgiving off-centered performance
Ring-Free Barrel Construction: allows for more barrel flex and increased performance with no "dead" spots
Professionally Inspired Handle: removable taper and an ergonomic knob shape for more top-hand control and comfort
Micro-Perforated Soft-Touch Grip: soft and tacky grip for improved feel and control

The CAT8 comes standard with a gray 1.75mm grip
Grip weight and manufacturing tolerances may cause slight deviation from the listed weight

    UPS lost my original order. After emailing customer service I had my grandson’s new bat the next day! His batting average has skyrocketed! Wish you could see his happy face!

    Great Bat - Love the Sound of Power!

    Posted by Deezy Villa on Dec 29th 2021

    Looks like this was one of the top bats out there, one piece as well. I wanted a small step up from my sons first bat and this is excellent and a huge step up. I love the sound and pop with both soft and hard baseballs. I hit a few myself and it flies off the bat. I've only had a few bats so thus far, the best we've had. He's a taller 6 year old and is able to swing it fairly well. I think when he's 7, he'll still be able to use it and really belt it.

    The bat speed, pop, balance is spot on. This is a great bat. My phone blows up after people see my son hit with this bat asking where did I get it, how well does it swing...

    Amazing Bat

    Posted by Brad Sullivan on Feb 6th 2019

    My 5 year old son played with the 26" Cat6 last year. I did not notice much difference between the Cat6 and the other bat we had. But, it definitely felt more balanced. This year I purchased the 27" bat for him. Wow, the ball is flying off the bat and it did not slow his swing down. Great Job Marucci.

    Used my new bat for the 1st time at UNLV Baseball camp. WOW! The "ping" sound off the bat and the POP is just amazing! Lightweight and easy to swing. Also the engraving is great. Great product.

    As a travel ball coach, I'm always looking for any advantage I can give my team... The ball just sounds different coming off this bat. The all new CAT8 definitely won't disappoint.
