2019 Marucci CAT6 GEN 2 Review: Bringing Back A Classic

Working with Marucci decided to bring back one of their most popular bats. The CAT6 GEN 2 is literally a remake of the 2016 model that was produced.

The only difference in the 2019 model is that the bat is red instead of white. The balance, material, and design are all identical to the original.

2019 Marucci CAT6 GEN 2 Review

It’s important to note that the CAT6 GEN 2 is a special model that was released by That means that it’s going to be tough to find this bat anywhere else. Looking at the site’s CAT6 GEN 2 reviews, customers really seem to like it.


Marucci has only been around for about 15 years. The company was developed by former players (Kurt Ainsworth and Joe Lawrence) which gave them instant credibility.

They’ve become one of the most popular brands in baseball. In fact, they’re one of the two most popular brands in Major League Baseball.

Marucci is a brand you can trust because you see guys like Bryce Harper, Andrew McCutchen, and Giancarlo Stanton using their bats.

Understanding the Terminology

Marucci does a great job of making their product approachable. They don’t really use fancy terminology. Instead, they trust a straight forward approach and a quality product.

AZ3000 Alloy

A high-end aluminum alloy that was at the top of the market in 2014 when the CAT6 first came out.

Ring-Free Barrel

Most top baseball bats today have rings inside the barrel. The rings are designed to increase durability and decrease the trampoline effect. They are what bat companies use to adhere to the ratings required for USA and BBCOR standards.

The downfall is that the ring causes a “dead spot” in the bat. Marucci has found a way to follow the standards without using rings.

Traditional Feel

Simply put, a traditional feel means the bat is balanced rather than being end-loaded.

Dampening Rate

This is a measurement for how much the bat is able to diminish vibrations or sting on a poorly hit ball. Marucci boasts that the CAT6 has a dampening rate that is 5.6 times higher than the next best option.

  • -3 model
  • One-piece alloy
  • Found in 31-33 inch options
  • 2 5/8 inch barrel
  • Great price point

As expected, the BBCOR model is very popular. It’s sleek red design makes it attractive to a lot of hitters. The single-piece alloy and balance makes the CAT6 a bat that most players can handle.

What I find really impressive is the cost of the bat. When looking at the best BBCOR bat models, prices are everywhere. The most expensive aluminum BBCOR you’ll find is about $300 while the most expensive BBCOR overall is about $450. The CAT6 GEN 2 sits beautifully at about $160.

Knowing the quality that Marucci produces and knowing that the CAT6 was one of the best baseball bats on the market when it first came out makes it an easy option to fall in love with. It’s not often that you can say you know exactly what you’re getting when you purchase a bat.

If you’re looking at the CAT6 as a BBCOR option this season, I’d definitely recommend getting the GEN 2 as the older version still runs about $150.

Marucci CAT6 GEN 2 USSSA Bat Review

  • -5, -8, and -10
  • One-piece alloy
  • 2 ¾” barrel

The USSSA models offer great flexibility with sizes that can fit almost any hitter. You can find the bat anywhere from 28 to 32 inches and bats that weight 23 to 27 ounces.

The sizes will slightly change the swing weight of the bat, but you can count on a balance feel in any CAT6 GEN 2 bat.

2019 CAT6 GEN 2 vs. The Competition

The truth is that Marucci has developed the league standard for vibration dampening technology. There is no bat that can measure up to what they’ve developed.

Aside from a clear win in that department, a few bats are comparable to the CAT6. We’ll ignore the obvious option that the first generation of CAT6 is a comp because they’re literally the same bat; Marucci just wrapped it, put a bow on it, and sent it back onto the market.

The Omaha 519 is a bat that fits the make and mold of the CAT6. It’s another one-piece aluminum alloy bat. It offers the same traditional feel to help promote a more balanced swing.

Louisville (the maker of the Omaha) has focused on vibration dampening. They still aren’t close to what Marucci has managed, but they’re trying. The price point is a bit higher than I’d like to see at, roughly, $200.

Another great option is to look at the 2019 Rawlings Velo. While it’s a one-piece bat, it is considered a hybrid because it’s made from an acoustic alloy. Rawlings wanted the bat to sound good.

What really impresses me is that Rawlings has come out with “half sizes”. To explain, let’s look at the BBCOR model of the Velo. The Velo can be found between 31 and 34 inches.

For most companies, that means 31, 32, 33, and 34 inch models. Rawlings decided to offer models at 32.5 and 33.5 inches as well. It may seem like something small, but today’s bats are all about feel.

With the new standards, it’s tough to have a “better bat” so companies are starting to focus on the ability to make different bats that feel better – bats that make hitters more comfortable.

The Velo comes with a hefty price tag at, roughly, $300. I’m not sure that it’s worth it.


Marucci has become one of the big names in bats in the last few years. They’ve only had five aluminum bats in the last eleven years. This shows their dedication to researching and developing significant improvements before putting out a new model.

I’ve always believed that the way to win over a customer is to provide a better product for a lower cost. To me, value is where the market should be focused.

When you look at bats that are $300 or more, you’re not going to find the value. I’m a fan of the CAT6 because it offers some of the best value on the market.

I also like that Marucci leads the pack in vibration reduction. One of the worst feelings a hitter can have is the pain of a bad hit ringing in their hands as they run to first base. Marucci has done its best to eliminate that.

I’m also a fan of single-alloy bats because it helps players prepare for the next level as the single-piece bats don’t have much trampoline effect. I think they act more like a wooden bat than the hybrids or multi-piece barrels.
