2019 Marucci CAT 8 Review

After a month of use with the BBCOR and USSSA versions of the CAT 8 we put together this 2019 CAT 8 Review.

(Looking for the 2020 USA Marucci CAT review?)

Models Overview

The bat upgrades a few pieces to the CAT 7 (which we review here).

Noticeably, the difference in the barrel length as the CAT 8 uses 8 different thicknesses of barrel wall. This was made possible by a change in the alloy. The CAT 8 still uses the patented AV2 knob which helps dampen sting. Our hitters, without surprise, loved the sound, power and feel of the 2019 Marucci CAT 8. More details follow.

You might also take a peak on the Money version of the CAT 8.

General Recommendations

Look, you just can’t go wrong with the CAT 8 from Marucci. The bat rakes, always has. People love the feel and sound. The barrel is big for aluminum (and manageable even compared to composite barrels. The price point is much more palatable than some other bats out there.

If it has anything going against it (and this isn’t really anything) is that it’s swing weight is heavier than some popular BBCOR bats. Don’t consider the CAT 8 a end loaded bat, but by no means is it a ultra light or ‘balanced’ swing.

Reviews By Model

Comparable Bats

No other single piece aluminum bat has sting dampening abilities in the knob. But, if you wanted someting with a fancy knob, we’d check out the Axe Avenge. Although the Axe is constructed much differently it does have a similarly unique knob.

In the single piece aluminum space there are not any bats that run as expensive as the CAT 8. It is a man among boys in that department—and for some deservedly so. The Cat 8 is legit. But, if you are looking in the stiff single piece aluminum world check out a bat like Slugger’s 518 Omaha. As well, you might like the stiff feel of DeMarini’s Voodoo Insane for 2019–although that is officially a two piece bat (but ultra stiff).

Previous Bats

The differences between the CAT 8 and CAT 7 are not monumental, but they are enough to warrant a conversation.

The biggest difference between the CAT 8 and the CAT 7 is the use of a different material in the CAT 8 that allows for another thickness in the barrel wall. The CAT 7, if you remember, has 7 different levels of thickness in the bats walls. This allows for a longer sweet spot and good weight distribution outside the center of the barrel. The CAT 8 upgrades its aluminum to provide for an 8th thickness. This expands the sweet spot even further.

It is impossible for us, or just about anyone, to measure the true differences between the CAT 8 and the CAT  7. Both bats, we are sure, are great. And our exit speed tests showed them perform quite similarly.


This is a single piece aluminum bat built with variable wall thickness. The CAT 7 was built similarly. And, turns out, that bat was fantastic. The CAT 8 comes in a BBCOR and big barrel option.

Our Parting Pitch

The CAT8 BBCOR is a 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.

• AZ105 alloy, the strongest aluminum on the Marucci bat line, allows for thinner barrel walls, a higher response rate and better durability
• Multi-variable wall design creates an expanded sweet spot and thinner barrel walls that are more forgiving after off-centered contact
• 2nd Generation AV2 Anti-Vibration knob features an upgraded, finely tuned harmonic dampening system for better feel and less negative vibrational feedback
• Ring-free barrel construction allows for more barrel flex and increases performance with no “dead” spots
• Precision-balanced barrel results in a lower M.O.I. and balanced feel for precision and control
• One-piece alloy construction provides a clean, consistent, traditional swing
• Professionally inspired handle features a removable taper and an ergonomic knob shape for more top-hand control and comfort
• Micro-perforated soft-touch grip with extra tack improves feel and control
