2018 CAT 7 Sizing

The CAT 7 is Marucci’s most elite bat. It comes in many different sizes and, really, there is a size for everyone. I really like the drop 5 and drop 8 in the big barrel. Here are a list of the sizes you can find.

  • Big Barrel Drop 5
  • Big Barrel Drop 8

2018 vs 2017 CAT 7 Sizing

Marucci releases their premier CAT line on a two year cycle. Meaning, the 2018 and the 2017 CAT 7 are exactly the same. If things go to form, expect a 2019 CAT 8 (or something like that.

They did make some upgraded bat designs in 2018 with the CAT 7 chassis. The first is a black camo looking bat and the second is a CAt 7 that looks like a Buster Posey wood bat.

CAT 7 Recommendations

The CAT 7 is a single piece bat built for maximum power transfer to the ball. That is, the stiff structure of a single piece bat has no give at contact like two piece bats.

The disadvantage of a single piece bat is that they tend to ring your hands on mishits. Marucci solves this problem by adding an anti-vibration knob in the knob to help dampen sting.

You will like the CAT 7 if you:

  • Like a Balanced, but not necessarily light, swing.
  • Prefer a stiff feeling bat.
  • Want Max performance and a big barrel for a more reasonable price.

Marucci CAT 7 Ratings


As a single piece aluminum bat the durability of the Marucci CAT 7 is tough to beat. The only issue you might run into is the knob which has its own insert, but that was more a problem on older models of the CAT.

As well, the CAT 7 does use a very thin aluminum in the barrel. But I have never seen a dented one. It appears to hold its shape well and it is a very durable bat.


In terms of user reviews, very few have ever complained about the bats production. I like the bat, like how it feels, and like what it costs for the pop. The barrel is a good size and produces a great sound on contact. I believe it produces distance like any bat money can buy.

Sizing Options

If the Marucci CAT 7 struggles anywhere it is the lack of sizing. I would love to see a 2 5/8 drop 10 as well as some options in the USAbat bat arena.

We do like the upgraded looks of the buster posey model and the black camo design, but the lack of sizing in those models leaves more than a few hitters dissapoitned—relegated to the 2107 CAT 7 look.

User Ratings

As we mention above, the Marucci CAT 7 User ratings are fantastic. If you are in the market for a light swinging BBCOR or big barrel bat that has tremendous pop and some decent feedback then look no further. Real hitters, including me, love the bat.

Overall Score

The 2018 CAT 7 is one of our favorite bats in the class. The fact the price point is a little more reasonable compared to other brands top shelf bat is a major plus. I am very high on this bat and recommend it to anyone who is looking for a great value purchase.

Also, Marucci’s site is usually worth a look too. There I could find a number of different sizing options as well as what colors were in stock.
