2018 Marucci CAT 7 Review | Year 2 Make Many Bombs

Click here to write review.

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. 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.

Where to buy the CAT 7?

We have bought bats from everywhere. Most major vendors have a selling account on Amazon and eBay so we almost always check their first.  Of course you can also check Marucci's site directly. And the plethora of online bat vendors have them in stock too.

What You May and May Not Like about the CAT 7

 

As a general recommendation, we think the 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.

Why You Might Like

  • 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

Why You Might Not Like

  • You want an end loaded bat
  • You prefer the more buttery smash of a two piece bat
  • A composite barrel is your preference

Marucci CAT 7 Sizes

The CAT 7 comes in nearly every baseball bat size you can image. When it was first released in 2017 it came in a BBCOR, Drop 8, Drop 5 and Junior Big Barrel (JBB). The JBB was a drop 10 in a 25, 26 and 27-inch version.

In 2018, the CAT 7 comes now in a Drop 10 as well as a few limited editions. As well, the Posey28 Pro Metal bat in BBCOR is a CAT 7 reprint too.

Expand below to see more details on the type of bat you are looking for.

CAT 7 USA

Marucci has explained they will not produce a USA Bat in any of their models. That includes, obviously, the CAT 7.

The reasoning is simple enough, they don't want the first experience a youngster has with a Marucci bat to be poor. And they beleive the USA Bat standard is generally a poorly thought out idea with bad reasoning and execution. As such, they have not produced a CAT 7 in a USA space. As of this writing there is no intent to change that.

BBCOR

Marucci CAT 7

The BBCOR version of the Marucci CAT 7 for 2018 or 2017 comes highly recommendable by us. In terms of value, we think it one of the, if not THE, best bat for your buck. We love the tappered knob, large barrel, loud ping and smooth smash on hits and mishits. We've seen hundreds of at bats with the CAT 7 BBCOR and can't remember a single player who didn't say anything but good things.

Drop 5

Marucci CAT 7

The Drop 5 might be the best Marucci CAT 7 bat in the line. Single piece aluminum bats tend to benefit from more weight and the 1.15 USSSA Stamp gives it maximum pop. If you can swing this bat, both physically and legally, we highly suggest you get one in your hands. Few ever go to anything else.

Drop 8

Marucci CAT 7

For the longest time, the Drop 8 Marucci CAT 7 was the lightest swinging version you could ever get. When they didn't have the drop 10 that they added in 2018, the claim was the drop 8 swung more like the drop 10. This wasn't perfectly accurate, the CAT 7 Drop 8 has a swing weight more in line with other light swinging drop 8's and 9's. The counter-balance weight in the knob (from the anti vibration feature) didn't offset the actual added weight of the bat.

Regardless, for a true drop 8/9 the CAT 7 drop 8 is a brilliant bat. We love the feel, sound and explosion on all parts of the barrel. Like the drop 5, if you can swing a drop 8, both legally and physically, then it should be on your short list

Drop 10

Maurcci CAT 7 Drop 10

JustBats.com struck a deal with Marucci to deliver a drop 10 CAT 7 to the market. At the time, this created quite the buzz. Folks have been clamoring for a Marucci CAT 7 drop 10 for what felt like years and they finally delivered.

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.

Limited Edition CAT 7

Marucci CAT 7 Limited

In the middle of 2017 Marucci also released a limited edition of the CAT 7 in a BBCOR, drop 5 and Junior Big Barrel Drop 10. (These drop 10's are only made in shorter lengths like a 27 and 28 inches). These are beautiful bats made to the same specifications of the CAT 7 but with an upgraded paint job look.

At the time of this writing several of these bats are still for sale.

Junior Big Barrel CAT 7

Marucci's Junior Big Barrel CAT 7 is built just like all the other CAT 7's on the market but comes only in a 25, 26 and 27 inch length.

CAT 7 2017 vs CAT 7 2018

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.

Why Marucci Uses a Two Year Cycle on Performance Bats

If you have paid even a little bit of attention to the performance bat space, you will have noticed that every major brand delivers a new iteration of their bat each year. That is, every major brand except Marucci. Marucci uses a two year cycle for their marquee bats. There is some real brilliance to this strategy, and a few major golf club manufacturers use the same approach. Here are a few of the benefits:

  • 2 year cycles allow for a company to get feedback from the players who use the bat to really develop an improvement in year 3. Since bats take more than 12 months of development, bat companies using a 1 year cycle must create a new bat without much feedback from year 1.
  • The old adage 'same old bat new paint job' is, in some measure, quite true. In the industry, changes between this year's bat and last year's bat often amount to very little. We document much of those changes on this site. And more often than not, the changes are a stretch in marketing language. A 2 year cycle allows for more substantial changes based on a year of good use.
  • Inventory from vendors is easier to manage over a 24 month period than over a 12 month period. As such, you'll find major sporting goods outlets are more willing to carry something that is not going to be outdated in less than a year.

3 Must Follow Social Medial Accounts for the 2018 Marucci CAT 7

Marucci CAT 7

No other bat, save maybe Dirty South Bats, has produced a social media following quite like the Marucci CAT 7.

Facebook: There are more than a few Marucci facebook groups, some of which are dedicated entirely to the CAT 7.

Instagram is also a useful too, at least in terms of aesthtics. To see a lot of CAT 7 stuff then @marucci is a huge must follow.

Twitter's Marucci Sports account is a good follow too if you want to see the lights and glamour of the Marucci CAT 7.

CAT 7 Construction

  • 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.
