Pros:  This bat is very balanced compared to many on the market thus making it swing lighter as well. It's just an ounce over it's stated weight(many other brands are close to 2oz heavier than stated. The last 26" drop 10 bat we picked up weighs almost 18 oz.) My 6 year old son playing coach pitch loves the bat. Looks Great, Feels Great & Performs Great. Ball seems to really launch on solid hits. One thing I noticed when I had another 26" bat standing next to it is although they are the same overall length, the knob on this Cat7 is so wide, you actually lose about a half inch of barrel length. Our first Cat7 Junior dented the first weekend we used it and Justbats.com just sent me a return authorization and swapped it out instead of making me contact Marucci. For that I give Justbats.com 5 Stars as well!! The replacement bat has not dented and has been used by some of the stronger kids on the team-so that's a good sign that maybe we just got a defective unit the first time.

Cons:  Had to ding the durability simply because the first one dented in two places. So far the replacement is just fine after several weekends of play.

Pros:  The ball flys off the bat. The bat has withstood many rounds of BP (4.5 months) and 25 games of machine pitch. After the other kids saw my son hitting shots with this bat, they all started using it. Each kid who used it improved their distance and pop greatly. The bat is used for machine BP and games. It is very durable with no cracks or dents. The paint is scraped due to so much use but no damage. The grip is thick and soft makes me wish I could use it. The barrel is huge. The aluminum bat makes a high pitch pinging sound that everyone loves. I machine pitch to kids with Eastons, Combats and a TPX... I believe this bat is more solid. When we played in colder weather, the temperature did not effect the bat performance unlike the composite bats. I do recommend kids with small, sensitive hands to get the thick padded batting gloves. But most decent swinging kids will love the pop.

Cons:  Love the bat.

Pros:  This bat is just what we were looking for. It's the right size for my 7 year old. It sends the ball flying in the outfield, has a great sweet spot. Thanks to the representative for recommending this bat.

Cons:  The only negative remarks is why did I wait so long to find this bat.

Pros:  Great grip and low vibration

Cons:  extremely thin wall and therefore seems to result in lessor ball pop and reduced ball carry for the money. I tested the Easton Mako Beast composite, CAT 7 and Easton S3. Beast and CAT 7 seemed to be equal. Ball seemed to carry the same distance as the CAT 7 but CAT 7 seemed to have more velocity and therefore rolled farther. S3 for $99 outperformed them both. Wasted my $$ on the more expensive highly marketed bats and should have just stuck with the S3

Pros:  So far, the kid is swinging it great. We have only hit off the sling machine a hand full of times. It's an ounce heavier than his old bat, but he's getting used to it now. When he hits the sweet spot, the ball FLIES off the bat. Not ONE time has the bat vibrated his hands, so that's a huge plus for me.

Cons:  No cons - I should have gotten an ounce lighter, but that's not the bat's fault!

Would you recommend a shorter 26"/16 oz bat for a child who is approximately 45" tall and weighs 62 lbs? He is turning 8 in one month and plays coach pitch. He has a 28" Easton MAKO previously recommended, but his swing speed has gotten worse. Seems like he cannot control the larger bat as well. He tried a friends 26" Marucci CAT 6 and swung it really well! That seems too short for his age and build. What do you think?

Our sizing chart has your son listed at a 27'' 17 in the 2017 Marucci CAT 7 Junior Big Barrel Baseball Bat: MJBBC7. The 26'' could the right size for right now, but in the future I would recommend going to a 27''.

I've read that you recommend the senior 27/17 over the junior 27/17 for kid pitch due to is durability. I've read that they are made from the same alloy and was wondering what makes the senior bat more durable? Or what is the difference between the two?

A Junior Big Barrel bat, like the 2017 Marucci CAT 7 Junior Big Barrel Baseball Bat: MJBBC7, will have a thinner barrel wall construction than that of its Senior League counterpart - the 2018 Marucci CAT 7 -10 Senior League Baseball Bat: MSBC7X10. As a result, the manufacturers recommend only using a Junior Big Barrel bat for coach pitch leagues where the velocity is typically under 40 MPH's. Once the velocity exceeds this threshold, the likelihood of the bat breaking down increases.

Can this bat be used in machine pitch with a range of 39-42 mph?

Yes, the 2017 Marucci CAT 7 Junior Big Barrel Baseball Bat: MJBBC7 is only intended for use in either coach or machine pitch.

Sammy is playing U6 - he's 6 years old 64 pounds and height 4'1". What do you recommend?

Does this bat come with the USSSA stamp that was the old stamp?

Yes, this bat does have the USSSA stamp that was used last year and still is used for travel baseball. It does not have the new USA certification stamp.

What bat should I get my 7 year old? He is 47” tall and 48 lbs. I'm considering the CAT 7 Junior Big Barrel bat in the 26"/16 oz. or 27"/17 oz. sizes or the new CAT 7 drop 10 (27"/17 oz.).

Based on your player's age, height and weight, I would recommend getting a 27" bat. If your player is playing coach pitch, I would suggest this 2017 Marucci CAT 7 Junior Big Barrel Baseball Bat (MJBBC7) but if he is playing kid pitch, I would recommend the 2018 Marucci CAT 7 -10 Senior League Baseball Bat (MSBC7X10). Junior Big Barrel bats (like this MJBBC7) are not meant to hold up hitting balls thrown over 45 mph.

My 6 year old plays for Cal Ripken/Babe Ruth league. Will he be allowed to use the Cat 7?

This 2017 Marucci CAT 7 Junior Big Barrel Baseball Bat (MJBBC7) features a 2 3/4" barrel diameter which will not be permitted for use in Cal Ripken/Babe Ruth baseball. He would not be able to use this bat.

Is this bat compatible with kid pitch? If not, what bat do you recommend for an 8 year old?

I would not suggest the 2017 Marucci CAT 7 Junior Big Barrel Baseball Bat: MJBBC7 for kid pitch. I would look at the senior league bats. Junior Big Barrel are designed for younger players with little velocity on the ball.

My son is 7 years old and his height is 47 inches and he weighs between 45-50 lbs. Please tell me the best bat size to purchase for my son. He's playing in coach pitch this year, and he's a pretty good hitter as this is his 3rd year playing baseball.

I would suggest 2017 Marucci CAT 7 Junior Big Barrel Baseball Bat: MJBBC7 in the 27" 17oz. size for your player.

I just got the CAT 7 Junior Big Barrel. It says on the bat that it is intended for coach pitch. My son is 7 and playing on an 8u select team. Kids will pitch not the coaches, is there a concern with the bat denting? Can it withstand kid pitching?

Ideally you do not want to use the 2017 Marucci CAT 7 Junior Big Barrel Baseball Bat: MJBBC7 in kid pitch. The speeds and strength of the players can dent the bats easier than normal. You would be better off going with a Senior League bat for kid pitch.

Can this be used for t-ball? Still have 2 more seasons of t-ball but son wants a big barrel.

You would have to check with local t-ball league to make sure that they allow 2 3/4" bats.

What size should I get for my almost 6 year old? I'm not sure on his height but he weighs 55 pounds. I'm hoping it will last about 2 years.

A junior big barrel bat like the 2017 Marucci CAT 7 Junior Big Barrel Baseball Bat: MJBBC7 is a good fit for those participating in coach pitch leagues. It would be tough to say whether a player would be able to get 2 years out of a bat especially with the new bat rules that will come into affect January 1st, 2018. As for the best fit, without the player's height it would be tough to give an accurate assessment but you may want to consider a 27 inch model.

My 8 yr old is about 4'9" and 92 lbs. Would you recommend a 28 or 27 in? He is currently in his last season of coach pitch.

Based on your son's height and weight we would recommend a 28" Junior Big Barrel Bat.

My son is 6 and plays coach pitch. I am looking for a bat for him that will help provide more pop. He is a bigger kid but worry about it only being drop 10. How is this bat balanced? Is this a good choice for a 6 yr old?

The 2017 Marucci CAT 7 Junior Big Barrel Baseball Bat (MJBBC7) is a balanced bat. I would not worry about this being a -10, it is one of the highest rated bats around. This is a great choice for a 6 year old.

My son is going to be in 8U coach pitch. What is the difference between the Cat 7 JBB and the 2016 Marucci Hex Alloy?

This 2017 Marucci CAT 7 Junior Big Barrel Baseball Bat (MJBBC7) will differ from the 2016 Marucci Hex Alloy Senior League Baseball Bat (MSBAHAX10) in regard to the intended use of the bat. This Cat 7 is is only meant for use in coach pitch and machine pitch baseball. The Hex Alloy will be meant for use in kid pitch baseball (technically, it could also be used in coach pitch and machine pitch baseball too).

Does the Cat 7 Junior Big Barrel have the same expanded handle base that connects to the knob that the Cat 6 has. The Cat 7 BBCOR seems to have it, but the pictures for this bat seem to show a flat handle at the knob.

The 2017 Marucci CAT 7 Junior Big Barrel Baseball Bat: MJBBC7 does not feature the tapered knob. The knob gets more tapered depending on the size of the bat. For example the -8 is more tapered than the Junior Big Barrel, the -5 is more tapered than the -8 and the BBCOR is more tapered than the -5. This is to provide a thicker handle base for the players as they grow.

Is this bat a huge upgrade over the CAT 6?

This 2017 Marucci CAT 7 Junior Big Barrel Baseball Bat (MJBBC7) is going to feature some significant improvements in technology over the CAT 6 that I think would characterize it as an upgraded bat. It features new AZ4X Alloy that increases the strength of the barrel and allows for a higher response rate. As well, this bat also features an optimized barrel design to allow for a sweet spot that is twice as large as what is featured on the CAT 6.

My son is 7 years old and playing kid pitch travel ball. (1) What are the cons of using this bat with kid pitch? (2) How does the bat compare to a Senior League bat (in regard to performance and durability)? (3) Will there be a -10 Senior League bat available for the CAT 7?

(1) This 2017 Marucci CAT 7 Junior Big Barrel Baseball Bat (MJBBC7) will be a Junior Big Barrel Bat that is meant for use in coach pitch and machine pitch baseball. The barrel walls are a little thinner and may not be able to hold up to the durability demands of kid pitch baseball (if balls are being thrown over 40-45 mph). (2) A Senior League bat will have walls more built to handle the higher velocity pitching (45+) that is often thrown in kid pitch. However, I think the bats will be able to perform pretty similarly overall. (3) The CAT 7 is not made with a -10 length-to-weight ratio and Senior League certification.

We are in an 8U coach pitch league. Is this a legal bat for Little League coach pitch?

This 2017 Marucci CAT 7 Junior Big Barrel Baseball Bat (MJBBC7) will come with a 2 3/4" barrel diameter to it. If you are playing in the official Little League, then the 2 3/4" barrel bats will not be allowed. However, it would be worth checking with your league to see what the exact bat requirements are for the division.

One of the main differences from last years CAT 6 to this CAT 7 is the new and improved AZ4X Alloy that dramatically improves durability and strength. Additionally, the optimized barrel design is more responsive and offers a sweet spot that is twice as large in comparison to the CAT 6. Through Marucci's engineer's extensive research and consultation with their player advisory board made up of big leaguers, they determined that one of the most common complaints among amateur baseball players is vibration in the hands. The brand-new AV2 Knob, also known as the second generation anti-vibration knob, offers a much better feel and remarkably less vibrational feedback in players' hands. Furthermore, the proven ring-free barrel technology continues to produce unmatched performance with absolutely no 'dead' spots. The combination of these new features results in a traditional, one-piece, all alloy, best balanced, most forgiving, sweetest feeling, and hardest hitting bat available.

The 2017 Marucci CAT 7 Junior Big Barrel Baseball Bat: MJBBC7 features a -10 length to weight ratio, a 2 3/4 inch barrel diameter, and the USSSA 1.15 BPF certification. Also, Marucci is backing this monster of a bat with a full twelve (12) month manufacturer's warranty. Marucci: Honor The Game! Be the talk of the town and make sure to get your own CAT 7 today with fast, free shipping.
