DeMarini Gattaca BBCOR Bat Review (2021 and 2020)

By Bat Digest | Last Updated October 20, 2021


Big hitters will like this bat. Don’t expect to get any extra umph if you are a base hitting type. Stay in the composite realm. But, those who swing with considerable power will see the benefits of the bat.

2020 Gattaca Models


We spoke with engineers responsible for the 2020 Gattaca at DeMarini. As well, we spent hours reading up on their site and discussed the 2020 Gattaca with a number of bat experts. In short, the Gattaca is a hybrid bat that uses unique inner barrel grooves to optimize the flight path of well hit balls. We discuss more of the science below in our 2020 DeMarini Gattaca BBCOR Review.

General Recomendations

Initially, we like three things about the 2020 Gattaca: design, innovation and price. First off, the bat is comprised of a two piece hybrid design that uses many of the elements found in the beloved DeMarini Voodoo. Secondly, the technology in the aluminum barrel enhances performance in a BBCOR world where many manufacturers have found themselves stuck at the limit. And finally, although more expensive than your standard two piece performance hybrid in the BBCOR space, the Gattaca has a reasonable price point—DeMarini isn’t hoping to recatpure all their R&D on the first run of the bat.

Comparable Bats

There are no other bats with parallel grooves inside. A few do have changes to the width of the material within the bat. (Marucci’s CAT 8 and the VELO, for example). The Mizuno MaxCor does try and improve the ball’s flight–albeit a complete different way in which the DeMarini Gattaca does.

2019 DeMarini Voodoo Balanced Review BBCOR

But, in terms of a heavy hitting 34 inch hybrid we’d suggest you look at DeMarini’s Voodoo Insane. The bat is very comparable to the Gattaca in that it uses a very similar handle, outer barrel and end load. Inside the barrel, of course things are quite different.

2019 DeMarini Voodoo Balanced

For the more balanced 33 inch version Gattaca, the most comparable bat is DeMarini’s Voodoo Balance. Like the Insane version, this is a hybrid bat, but it comes with a lighter swing. The handle between the Voodoo and the Gattaca are very similar.

Previous Models

There is no 2019 version of the DeMarini Gattaca. It was a D-Lab creation and produced in 2019 but only for their site. For 2020 season you will see it in a 2020 version (really the first version) with broader distribution. (Like, you’ll find it at your favorite online shop).

Construction

Understanding why the Gattaca launches well hit balls with more consistency takes a decent understanding of how bats and balls interact. It is more complicated than most appreciate—or care to appreciate.

How does it work?

2020 DeMarini Gattaca Review

To gain a cursory understanding of how the bat claims to improve performance, know this much:

  1. The 2020 Gattaca uses multiple angled grooves–roughly 1/4 inch thick–on the inside of the barrel. These angles move lengthwise (from knob to end cap).
  2. These grooves are angled such that, at impact, the angles are parallel to the ground.
  3. Since optimal bat paths tend to be slightly upwards the grooves are angled based on the bat’s path. This is why the left and right handed bats are different—since the swing plane of a left handed hitter is the opposite of a right handed hitter–the grooves in the right (blue) and left (red) bats are angled opposite of each other.
  4. DeMarini’s data claims that, when compared to a non-grooved bat, hitters get more consistently optimal ball flight on well hit balls when inner-barrel grooved angles are parallel to the ground at impact.
  5. The claim is not that balls will now fly further than they ever have—DeMarini has not broken the BBCOR barrier with the Gattaca. Instead, the claim is that optimally hit balls (good launch angle, contact and swing plane) will produce more consistently optimal hits because parallel grooves in the barrel at impact optimize the impedance matching.
  6. As a fictitious example, if a given player hits six home runs in a year and flies out eight times to the warning track, the idea is they’ll now hit ten home runs in a year with four fly outs to the warning track.
  7. It follows, then, that if you’re not hitting some balls out and some balls to the warning track then the Gattaca might not be for you. If you are a smaller hitter, without home run or gap type power, parallel grooves on the inner barrel won’t improve your OPS. (Neither will it hurt your OPS).
  8. Power type hitter who miss out on a few extra base hits and a couple dingers a year might find a huge benefit in the Gattaca.
  9. This benefit mostly to power hitters is why the bat does not come in smaller sizes (like a 32 or 31). That is, because smaller hitters won’t necessarily appreciate the added optimization a grooved barrel brings to their non-existent long ball.

Impedance Matching: What you Should Know

Impedance matching is a term the bat industry uses to describe how a bat and a ball interact with each other. The general sentiment is simple enough even if the physics behind it is more complicated than is useful for us here. As a bat and a ball collide, the way in which they squish and rebound matters, a lot. That concept determines, in large measure, how bats vibrate to your hands, how much energy is transferred to the ball and how the ball’s spin, trajectory and exit speed are affected.

All other things equal (speed, collision force, mass, etc.), the characteristics of the material that make up the barrel of a bat measurably affect ball flight BECAUSE the material and its structure determine how it squishes and rebounds when colliding with a ball. We call that give and take, or how a bat and ball squish and rebound simultaneously to create flight, impedance matching.

Does the 2020 Gattaca Improve Impedance Matching?

We can’t find anything self-evident as to how inner-barrel parallel grooves at impact improve the impedance matching of well struck balls. But, the lack of obviousness doesn’t mean it isn’t true. Outside of a million dollar lab we aren’t sure how we could objectively check such a claim—as much as we like our Rapsodo.

We have enough experience with DeMarini and their well performing bats to give them the benefit of the doubt—the market and time usually do a good job of fleshing out performance claims. And considering their claim sounds reasonable—that a change in barrel structure improves the ball’s rebound effect on SOME hits—our general gut feel is that it is true.

But, how true is it? We mean, how noticeable will such an improvement be to the average big hitter? DeMarini’s test showed that a power hitter put 10% more of their hits into their maximum range. So, 5 or 6 more hits going a few feet further on any given BP session is likely not readily apparent. But, over the course of the season, might make all the difference.

If the bat performs as well as the Voodoo, and all signs point to the fact that it does, then for many power hitters the $50 increase for the Gattaca will likely be worth the bet.

Overall Ratings

The overall rating uses seven different weighted metrics to determine our overall score. Half of total rating comes from the player and our exit speed tests (Player Rating: 25%, Performance: 25%).The other categories are Relevance (20%), Demand (10%), Durability (10%), Resell Score (5%), and Tech Specs (5%).

(UR) Un Rated: An overall rating of UR means the bat has yet to be fully rated. When it is, this score will update.

(PlaRa) Player Rating: We measure player rating from user reviews. Those users include our own hitters that we test at the lab as well as reviews we find online.

(ExVe) Performance: Performance measures the exit speeds and distances we capture in our hitting lab with HitTrax using these bats.

(Relv) Relevance: We measure the number of sizes and the MOI of the bat. Bats with a wider range of options get a better score.

(Dmnd) Demand: Demand is measured by consumer sentiment and the buzz around the bat.

(Drb) Durability: A bat’s durability is measured by user reviews as well as feedback from manufacturers.

(ReSl) Resell Score: Based on the price the bats go for used. Higher prices mean greater user demand which means, generally, a better bat. A resell value closer to its original price means a higher score.

(Tech) Tech Specs: We rate the bat on its technological advancements from previous years and compared to the industry at large. This is our chance to reward companies who are trying to innovate.
MOI
MOI or Mass Moment of Inertia is a measurement of bat swing weight. This quantifies how difficult it is to swing a bat. The industry often refers to this as things like End Load or Balanced but those words have been overused to the point of meaninglessness. We measure the actual swing weights of each bat we test using the industry-standard pendulum period, balance point, and scale weight. You can read more about that here.
Price
The price is the original MSRP price of the bat.
Type
The types of bats are single-piece alloy (SPA), two-piece composite (TPC), single-piece composite (SPC), hybrid (Hyb.), and wood (Wood). Hybrid bats are made of composite handles and alloy barrles.
Date
The estimated date the bat began distribution.

is the gattaca banned in high school use.

Charlie Hussin says:

so if i bought a 34 inch bat could i make it a 33 inch bat by adjusting the knob

Brian says:

That is correct. The 34 could be come a 33 or 33.5-inch.
