2019 Marucci CAT 6 (Gen 2) Review

October 14, 2021 | by Bat Digest Review Team | @BatDigest

JustBats purchased the exclusive rights to the CAT 6. That is, the updated look on the CAT 6—with the red base and white accents—is a JustBats only bat. The expectation, as far as we understand it, is that such will be the case indefinitely. Making such an arrangement, as far as know, a first.


The new CAT 6 is nothing new structurally from the older CAT 6. But, in so many ways, that is not a bad thing at all…

Quick Review

The new CAT 6 is nothing new structurally from the older CAT 6. But, in so many ways, that is not a bad thing at all…

The CAT 6 has been one of the highest rated bats ever. It has great sizing options, feels great and prices right where most people want it to be.

It has a middle of the road swing weight and uses the same proprietary knob found in new CAT bats from Marucci.

As a general sentiment, we’d recommend the bat for any player that prefers the stiff feel of a single piece bat and is looking for a real value purchase. The sizing options at JustBats make it available for any player. The heavier the weight (drop 8, drop 5, BBCOR) the more we tend to prefer to the CAT 6.


BBCOR CAT 6 Recommendations
2019 Marucci CAT 6 Review

Hitters who like the honest feel and power that come from a one piece bat but also want to avoid its associated sting; Want a one piece bat; Prefer a balanced bat; Want a top shelf bat but don’t want to spend top shelf money; Prefer a two-piece bat but want to find a one-piece bat that swings with the same smoothness that two pieces do; would rather have an aluminum barrel.
On the other hand, those who want an end loaded swing; are in little league and need a real light swing (as the CAT 6 is only in a max drop 8); are in little league and prefer a composite barrel.

2019 Marucci CAT 6 Review

Overall the Original CAT 6 is, in justbatreviews opinion, the most beautiful BBCOR bat on the planet. The bat is sleek with a kissable and sheen finish. The angelic white with gray and red accents make it look like a bat designed in the halls of Prada.
As per performance, we think the CAT 6 is a top shelf BBCOR bat that will perform, out of the wrapper, at the highest allowable .50 BBCOR standard. It’s big barrel (especially for a full piece aluminum bat) is remarkable. We are sure that those who fell in love with the CAT 5-Squared will fall in love all over again with the CAT 6.

Comparable Bats

The Cat 6’s sting dampening knob makes it otherwise unique. No other bat uses such a tech (they can’t as Marucci has the patent). But, you can find some single piece aluminum bats from 2016 in the Omaha 516 and the Rawlings VELO. Both are legit choices, a bit ligther and also run a bit cheaper.

For the CAT 6 Generation 2 you can find similar bats in, wait for it, the CAT 6 Gen 1. As well as bats like the 519 Omaha and 5150 from Rawlings. None of them have the technology in the knob or as big a barrel—but they also cost less.

We spent three hours in the cage using the 516 in comparison to other single piece alloy bats and other bats in the 2016 Slugger line up

2016 Velo

We spent a good amount of time in the cage and on the field with the 2016 VELO. Our 9 year old player, who weighs right at 65 pounds, fell in love with the 2016 VELO drop 12 2 3/4 two piece composite.

2019 CAT 6 Construction

Another notable change to the bat is its design. The CAT 5-Squared was designed in gray backing with black and red highlights and a black grip. On the CAT 6, the bat is a very glossy pearl white with sort of hologram hurricane circles in the design. (Get it? CAT 6, Hurricane, as in a Category 6 Hurricane?). The grip is gray to match the highlights on the bat.

On the BBCOR version of the bat Marucci also shaped the handle to transition into the knob. This larger widening handle increases the bottom hands contact to the bat which many hitters like. Those who like a skinny bottom hand handle can unwrap the tape and remove the plastic shaped cone on the bottom of the handle.

Bat Sizing Options

The CAT 6 Generation 1 comes in a drop 3 BBCOR, Senior League (2 5/8 Barrel) of drop 5 and drop 8 and well as Junior Barrel Version (2 3/4) in a drop 10.

The CAT 6 Generation 2 comes in all the same sizes as the Generation 1.
