2018 Marucci CAT 7 Review

By Bat Digest | Last Updated August 27, 2019

However, each year they do add a few models to the line. In 2018 they added a drop 10 to round out their drop 8, drop 5 and drop 3 (BBCOR) versions of the CAT 7. Generally, the bat gets very high marks from us (and users). After hitting with every version of the 2017/2018 Marucci CAT 7, multiple times with multiple hitters, here is our full review.

As a general recommendation, we think the BBCOR CAT 7 is made for the gap hitter that likes the stiff feel of a single piece bat more than the soft crush of a two piece stick. Here’s who this fits: You want the best metal bat Marucci makes; You prefer a good value purchase on a performance bat; A durable bat that can last a good season or two is on your short list of features; Your stat sheet is filled with singles and doubles and a high AVG.

On the other hand, those who want an end loaded bat, prefer the more buttery smash of a two piece bat or want a composite barrel should look elsewhere.

The 2018 Marucci CAT 7 is the same as the 2017 Marucci CAT 7. Marucci doesn’t hide this idea. They release their performance bats on a two year cycle.

Comparable Bats

Does anything really compare to the CAT 7? A big barrel in a single piece aluminum is hard to come by. And the added unique know with its sting dampening skills makes it hard to find an equal. The CAT 7 also prices out above most single piece aluminum bats anyways.

If you we had to shoot for something in a similar class then take a closer look at the Omaha 518 from Slugger. Both bats have stiff feels, decent sized barrels and come in a number of sizes. Or, maybe, the 2017 VELO from Rawlings. That Velo will swing lighter than the Cat 7, but its worth a shot if you’d like something with a lower price point.

Looking at the Posey Metal 28 is cheating. That bat, in BBCOR at least, is the same as the CAT 7 with a different paint job.

Previous Models

In terms of construction there is no difference in the 2017 CAT 7 vs the 2018 CAT 7. They did add the drop 10 version as well as some limited edition version (as we mention above).

Marucci makes no bones about it being the same bat. As a site that reviews bats we can appreciate this approach as many companies are often guilty of changing the paint job and calling it something else. Not with Marucci; the 2017 CAT 7 is the 2018 CAT 7.

Marucci uses this two year cycle on all of their performance baseball bats.

  • Single Piece Aluminum: Single piece aluminum bats are, just that, single pieces of aluminum bats. They are made of one single piece of an aluminum alloy from knob to end cap.
  • Barrel Size: The Barrel on the CAT 7 is 50% longer than the barrel on the CAT 6 due to a change in the taper of the inner barrel. Simply, the insides of the barrel are thinned out to 7 different levels that help increase the length of the barrel without messing with the swing weight. The 7 thickness levels of the inner barrel are a coincidence in the name CAT 7 (which refers to hurricanes).
  • Knob: Inside the knob of the CAT 7 sits a small rubber piece. This piece is designed to lessen the vibration of the bat on mishits. Marucci has some studies that prove this is true. Our experience proves to us that it is also true. The bat fees better on mishits than other single piece aluminum bats.

Mareting Writeup

If we’re being frank, we think the drop 10 loses too much weight to keep the same smooth feel as the drop 8 and drop 10. The loss of the extra mass really removes a lot of the confidence players have in the drop 8 and drop 5. However, those with slower swing speed that saw slower pitch speeds still really liked the drop 10. But, once pitch and swing speeds got faster the CAT 7 Drop 10 lost its appeal. We would suggest most serious players stay with the light swinging drop 8 if they can swing it.

Overall Ratings Key

To keep consistent ratings across years, models and brands, we’ve devloped an aggregated rating system using 6 categories. As well, we track swing weight (MOI), stiffness and profile although they do not affect the overall score directly. The explanation of each rating is below.

  1. MOI: is the swing weight accurately measured at our bat lab. We score it 1 through 5. No score is better than another. This is a descriptive value. A lower number (1) represents a light swinging bat for its class, while a higher number (5) represents an endloaded bat.
  2. Tech: The tech advancements in the bat are 5% of its overall score. We award points for innovation even if the invention encourages the industry to try new things.
  3. Durability: The bat’s lifespan is rated at 15% of the overall score. We gather this information almost exclusively from the user and player feedback. More reports of a bat breaking then the lower the score.
  4. Stiffness: Stiffness is not counted towards the overall score since it’s a complete preference. The higher the number, the stiffer the bat, the lower the number, the more flex in the bat directly after contact. This is significantly correlated to how good a bat feels on mishits and hits.
  5. Profile: The profile does not count towards the overall score. However, we do track it. A high number means the bat has an extensive profile, and a lower number means it has a small profile.
  6. Resell: We count the secondary market of a used value of the bat as 10% of the overall score. We think the demand for the bat in the secondary market (eBay and SidelineSwap) are a good indicator of how well the bat is perceived to perform. It also shows a more excellent value for the owner as their bat retains more value and no longer becomes valuable to them.
  7. Rating: This is the player rating and represents 25% of the overall score. These are gathered from our hitters and reviews we find online and those we have contact with from other reputable sources.
  8. EV: Exit Velocity is the rankings we create in our exit speed velocity tests every year on bats. This score represents 25% of the overall score.
  9. Relevance: Relevance measures how applicable and available a bat is for consumers. The broader range of sizes and the more appropriate the swing weight for the masses then, the higher the score. This metric accounts for 20% of the overall score.
