Description
expand_moreThis Marucci CAT 7 Senior League Baseball Bat is similar to that of the CAT 5 and CAT 6, only double the power! You are really going to scare some people if you come to the plate with this bat. Marucci has done a fantastic job of upping the ante from year to year and improving on an already masterful design. 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 Marucci CAT 7 Senior League Baseball Bat: MSBC75 features a -5 length to weight ratio, a 2 5/8 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!

dingernation
The new 2017 Marucci CAT 7 Senior League Baseball Bat: MSBC75 will have a larger sweet spot compared to the CAT 6 model and the new AZ4X alloy, in combination with the optimized barrel design, will give the bat better durability and more pop. As for the handle, it will feature a slightly different grip tape but other than that it will be the same.

Damon
I'm a 12 year old boy, 5'6", 160 lbs and will be going to the 60/90 field. What drop do you think I should use? I am currently using a -9 Voodoo 2015. What do you think I should use?

I'm 12 years old, and 5'11" and weigh 137 lbs. Which size of this would be best?
sba buck
For a player of your size, I'd recommend getting the 2017 Marucci CAT 7 Senior League Baseball Bat: MSBC75 in the 32" 27 oz. size.
Marcus
Is there a break-in period on the 2017 Marucci CAT 7 Senior League Baseball Bat: MSBC75?
NICK
The 2017 Marucci CAT 7 Senior League Baseball Bat (MSBC75) is an aluminum bat and will not need any break in period. This bat will be hot right out of the wrapper.
Carter
My son is 13 and 5'2", weighs 107 pounds. What size bat do recommend?
Ray
Based off of his current height and weight we recommend a 31" in the 2017 Marucci CAT 7 Senior League Baseball Bat: MSBC75.
Cooper
My son is 5'7" & 110 lbs. He will play 14U ball next year. What size bat do you recommend?
Scott
Based on his height and weight we would recommend a 31"/26 ounce 2017 Marucci CAT 7 Senior League Baseball Bat (MSBC75).
Carter
I play 14U travel baseball, does this bat follow the requirements?
Aidan Catania
It would be best to double check with a coach or a league official, but the 2017 Marucci CAT 7 Senior League Baseball Bat: MSBC75 features the USSSA 1.15 BPF stamp, which should make it legal for play.
Jason
My son is 14, 5'5", approx 125-130 lbs. What size bat would suit him best? Does not require BBCOR for another year.
Scott
The 2017 Marucci CAT 7 Senior League Baseball Bat: MSBC75 in a 32 inch 27 oz option would be suitable for his size.
Linsey
What is the better bat to pick: the CAT 7 or the VELO?
Joey j p
This 2017 Marucci CAT 7 Senior League Baseball Bat (MSBC75) is one-piece, all-alloy, balanced and it also receives great remarks from customers. The VELO is pretty solid as well. The biggest difference between the 2 bats is that the VELO will feature a composite end-cap to make the bat feel a little more balanced. Overall, either bat will be a great pick in my opinion.
Ben
What is more balanced: the CAT 7 or the Omaha 517 bat?
boby
This 2017 Marucci CAT 7 Senior League Baseball Bat (MSBC75) and the Omaha 517 will feature a one-piece, all-alloy design. Due to that similar design, both bats are going to be very balanced and it will be hard to say that one of the bats is far and away the more balanced swinging bat.
Ben
My son is about to be 12. He's been swinging a -10. Would a -5, be too much of a transition at one time (looking at a 30"/25 oz bat)? If so, which bats do you recommend?
Don
I think that your 12 year old should be able to make the transition to a -5 bat from a -10 bat. The 30"/25 oz size of bat should work for your player, but I would prepare for an adjustment period. If you wanted a bat that would provide less of an adjustment, I would look to the 2017 Marucci CAT 7 Senior League Baseball Bat (MSBYC78) that has a -8 length-to-weight ratio. You could get a 30"/22 oz size of that CAT 7.
Ben
Is the CAT 7 end loaded? How does it compare to the Rawlings 5150 -5?
Dad
The 2017 Marucci CAT 7 Senior League Baseball Bat: MSBC75 has a balanced swing weight. It is fairly comparable to the Rawlings 5150, as they are both one-piece alloy designs with balanced swing weights. However, The CAT 7 does feature an anti vibration knob to prevent sting and the AZ4X alloy provides the bat with a slightly bigger sweet spot.
Jason
I'm 14 years old, 5'7" and 120 lbs. What would be the right size for me?
catcher4444
Based on your height and weight, we suggest a 32" model of the 2017 Marucci CAT 7 Senior League Baseball Bat: MSBC75.
Jason
Is this bat stamped with "approved for play in Pony baseball"?
Jim
The only stamp on this bat is the USSSA certification and the BPF 1.15 certification. In most leagues the 1.15 BPF is enough for the bat to be legal, but you would have to check with the rules of your league to make sure that is the case.
Kyle J.
Does this bat weigh evenly throughout the barrel?
skeeter
The 2017 Marucci CAT 7 Senior League Baseball Bat: MSBC75 will have an even or balanced weight distribution throughout the barrel.
Cameron
How is the Alloy Hex compared to this? Which is better?
tdaddy
Both the 2017 Marucci CAT 7 Senior League Baseball Bat: MSBC75 and the Hex Alloy feature the same alloy material. The Hex Alloy is a -10, whereas this is a -5.
Logan
Is this bat right for my 13 year old who 5'4", 110 pounds? If so, what size do you suggest? He needs to move to a drop 5 from swinging a drop 10 in the fall.
Scott
The 2017 Marucci CAT 7 Senior League Baseball Bat: MSBC75 would work well for your player. I would suggest the 31" 26 oz. size.
Logan
Is this a BBCOR bat? Do BBCOR bats come with greater than drop 3?
Tom
This is not a BBCOR bat because it is a -5. All BBCOR bats are -3.
Kyle J.
Is this bat all composite?
Hitting Dingers
The 2017 Marucci CAT 7 Senior League Baseball Bat: MSBC75 is a one piece alloy bat, so it is not composite.
Logan
How long does it take to be delivered?
Matt
The 2017 Marucci CAT 7 Senior League Baseball Bat: MSBC75, and all other bats ordered, typically take 2-3 business days to be delivered with the free ground shipping option through UPS.
Cameron
My son is 13 yrs old, 5 ft tall and weighs 110 lbs. He is currently using a Mizuno Nighthawk 30"/20 oz. What size in this bat would you recommend for him?
turn2
Based upon your player's height and weight, I would recommend looking for this 2017 Marucci CAT 7 Senior League Baseball Bat (MSBC75) in the 30" length as long as you can handle the 25 oz weight.
Ben
What's the difference between the senior league and junior league model? My son is 13, which does he need?
ryan
For a player that is 13, one would need a Senior League bat like the 2017 Marucci CAT 7 Senior League Baseball Bat: MSBC75. A Junior Big Barrel bat is designed for coach pitch leagues with velocity under 35 MPH. These bats have thinner barrel walls and will break rather quickly if used by older players seeing pitching faster than 35 MPH.
Cameron
My son is 12 years old and 5'4" and 150 lbs. What size would you recommend?
Hi
We would get the 2017 Marucci CAT 7 Senior League Baseball Bat: MSBC75 in a 31 model based on your son's height and weight. For his age, typically a -10 or -8 bat would suit him better.
Cameron
My son is 13, about 5 foot and 95 lbs. He currently swings a drop 8 COMBAT but will need to move to drop 5 for next fall to prepare for 14u next spring. He is a lead off hitter, more contact hitter but can also hit bigger at times. What size bat would you recommend for his size?
Annie
Based on your player's height and weight, I would suggest the 2017 Marucci CAT 7 Senior League Baseball Bat: MSBC75 in a 30" length.
Logan
My son is pretty strong and a power hitter. He is 13, 5'7" and 160 pounds. What size would you recommend for him?
Based on his height and weight, we suggest a 32" model of the 2017 Marucci CAT 7 Senior League Baseball Bat: MSBC75.
Jason
My son is 13 and was using a MAKO big barrel size 30 inch 20 oz. Will this bat be too heavy for him?
rjtj
The 2017 Marucci CAT 7 Senior League Baseball Bat: MSBC75 is a well balanced bat, but will be quite a bit heavier overall than the 20 oz. bat he was swinging. If you needed to move to a -5 bat, this would be one of the easier bats to swing.
Logan
Is this bat USABat certified for the 2018 Pony league season?
lacuff
This 2017 Marucci CAT 7 Senior League Baseball Bat (MSBC75) will not have the USABat Certification on it and will not be permitted for use in Pony Baseball in the 2018 season.
Ben
My son has the -8 version of this bat and looking at the -5. But it looks like the handle on the -5 is wider near the knob. Is this right? The -8 handle is same width throughout. Can you confirm?
BulldogBaseball73
You are correct. The handle on this 2017 Marucci CAT 7 Senior League Baseball Bat (MSBC75) will taper into the knob (i.e. get thicker). The -8 version of the CAT 7 will not have a handle that tapers into the knob.
Ben
Know this does not have the USABat stamp, but do you know if this drop 5 bat will be legal for play in the 13-15 age division of Babe Ruth for 2018 league year?
Lefty
The 2017 Marucci CAT 7 Senior League Baseball Bat: MSBC75 will not be approved for Babe Ruth play in 2018 as only bats featuring the USABat stamp will be eligible. These bats will have thicker barrels walls than the current models of the 2017 Marucci CAT 7 Senior League Baseball Bat: MSBC75 and thus will have reduce performance capabilities.
Cameron
Can this bat be used in middle school? Not really sure of the rules concerning bats.
Brian Wray
Depending on what league you play in will determine if the 2017 Marucci CAT 7 Senior League Baseball Bat: MSBC75 is going to be legal. I would check with a coach or league official to see what the bat rules are in your league.
Cooper
My child is 13 and is 5'6" 150 lbs. What size Cat 7 would you suggest?
John
Based on your players height and weight, we suggest a 32" model of the 2017 Marucci CAT 7 Senior League Baseball Bat: MSBC75.
Jason
My son is 13, and will play 13u in the fall and next spring. He is currently 6-1, 180 pounds. The league rules allow a drop 10, but with his size and strength, we are looking at a drop 5. What size would you recommend for him?
T.
We suggest swing the heaviest bat you can consistently control with great bats speed, so a -5 would be the way to go, in my opinion, based on his size. I would suggest the 2017 Marucci CAT 7 Senior League Baseball Bat: MSBC75 in the 32" 27 ounce size.
Logan
My son is starting a 11u league this year. What bat do you suggest? 5 ft 4 and 95 lbs.
smalls
I would recommend a 31'' 21 oz. If you are not using the USA rules I would recommend the 2017 Marucci CAT 7 Senior League Baseball Bat: MSBC75.
Max
Is the BBCOR only for the -3 and not the CAT 7 -5 bat?
travelball
The BBCOR bats are used for the USA rules and are a -3 bat.
Mick
Does the CAT 7 -5 meet the USA Baseball standards? If so, is the marking on the bat?
T
The 2017 Marucci CAT 7 Senior League Baseball Bat: MSBC75 does not meet the USA Baseball standards for 2018. USA approved bats will not be available until September.
Logan
What size would you recommend for a 5'6" 125 lb 13 year old?
jake
Based on the players height and weight, I would suggest a 32" model of the 2017 Marucci CAT 7 Senior League Baseball Bat: MSBC75.
Jason
What size bat (-5) would you recommend for my son - 5'2" 100# ?
Dad
Based on your height and weight we would recommend a 31"/26 ounce 2017 Marucci CAT 7 Senior League Baseball Bat (MSBC75).
Carter
I"m turning 13 and 4"11' and 85 lbs. I want to get the Cat 7 but can"t decide if I should get a -5 or -8. What should I get?
Tony
Based on your height and weight, we suggest a 30" model. The drop weight is tough to suggest, as it really depends on your bat speed and strength. However, you have to use a -3 for high school and typically it is best for a 13 year old to swing a -5 like the 2017 Marucci CAT 7 Senior League Baseball Bat: MSBC75 if they can.
Jason
I am 12, 5'4", 115 lbs, and reasonably strong. What length and weight would you recommend for a 2 5/8" USSSA bat?
Soot3
Based upon your height and weight, I would recommend looking to a -5 bat in the 31" length as long as you can handle the subsequent 26 oz weight. This 2017 Marucci CAT 7 Senior League Baseball Bat (MSBC75) is probably the top-rated -5 baseball bat we are carrying at JustBats. If you wanted another solid -5 model to consider from Marucci, you could also look to the 2017 Marucci Hex Connect -5 Senior League Baseball Bat (MSBHCY5). That Hex Connect line of bats has been rated well overall and if you wanted a two-piece, all-composite bat with a -5 size to consider, that would be a good one to view.
Ben
Can I hit total control balls with it without damaging it?
CAT 7 Mafia
If you are referring to the weighted baseballs, over time they will shorten the lifespan of the bat and lead to a higher risk of durability issues due to the heavier weight. The bats are designed to hit standard baseballs, so anything heavier will shorten the lifespan.
Kyle J.
My son is 5'7" and 116 lbs. He is 13 and in the 7th grade but plays on a 14u club team. Do I go with the bat coach suggested 31" length or plan for growth and go up to a 32"?
David
Based on your sons height and weight we would recommend a 31"/28 ounce 2017 Marucci CAT 7 Senior League Baseball Bat: MSBC75.
Carter
Is this a balanced or end loaded bat?
Ken
The 2017 Marucci CAT 7 Senior League Baseball Bat: MSBC75 is a balanced bat.
Tori
My 14 yr. old grandson really likes your CAT 7 bat but we are struggling with size. He is 5 ft 10 in about 145 lbs and growing like crazy. We would prefer a drop 3.
grandpa
Based on your player's current height and weight, I would suggest a 32" 2017 Marucci CAT 7 BBCOR Baseball Bat: MCBC7. However, if you think he may grow quite a bit in the near future, I would suggest going with a 33" 2017 Marucci CAT 7 BBCOR Baseball Bat: MCBC7.
Logan
My son is 12, 5"5' and 107 lbs. He has been using a 30" -8 for the last 2 years and swings with plenty of bat speed. I am considering buying him this bat in -5. What are your thoughts on length? I was thinking possibly a 31", but don"t want him to lose a bunch of bat speed by jumping to the 26 oz.
Legends BBall 2018
Based on your player's height and weight, I would suggest a 31" 2017 Marucci CAT 7 Senior League Baseball Bat: MSBC75. I don't think a 30" would provide enough coverage for his size, and the Cat 7 is well balanced, so I don't think he will have much trouble transitioning to a 31/26.
Logan
Is this bat usable for USSSA leagues and tournaments?
6
Yes, the 2017 Marucci CAT 7 Senior League Baseball Bat (MSBC75) is USSSA approved and will be allowed for both leagues and tournaments.
Tyler
What is the difference between the CAT 7 and the CAT 7 Connect?
Brian Fulmer
The difference between the 2017 Marucci CAT 7 Senior League Baseball Bat: MSBC75 and the CAT 7 Connect is the one-piece all alloy design versus the two-piece hybrid design of the CAT 7 Connect. Both bats feature the same alloy barrels but the CAT 7 Connect will be more end-loaded in swing weight design, feature a composite handle and will be better able to reduce vibration from an off-centered hit.
Cameron
Which is the better cooler weather bat, the CAT 7 or the CAT 7 Connect?
Robyn
Because of the alloy construction of the 2017 Marucci CAT 7 Senior League Baseball Bat: MSBC75 I would go with the hybrid two piece construction of the 2017 Marucci CAT 7 Connect -5 Senior League Baseball Bat: MSBCC75.
Max
My son is 11, about 5'0", 112 lbs. The last two seasons he batted with a DeMarini 29"/20 oz -9. Thinking about changing him to a 31/26 -5 CAT 7. What size bat would you recommend for his size?
Dee
We would suggest a 30" length for his size and weight.
Kyle J.
What's the difference between -5 bats and -3 bats?
Broc Redenius
The drop weight is determined by subtracting the length in inches by the weight in ounces. Therefore, considering bats of the same length, the -5 bat will be 2oz. lighter than the -3 bat. However, all -3 bats will be BBCOR certified and would have a lower performance threshold than a USSSA bat like this 2017 Marucci CAT 7 Senior League Baseball Bat: MSBC75.
Tyler
My son is 13u, 5'0" and 88 lbs. Looking for a new big barrel bat. I'm thinking 30" -5 or -8. He's a good contact hitter. What do you suggest?
Little batter
Based on your son's height and weight I would recommend a 30"/25 ounce 2017 Marucci CAT 7 Senior League Baseball Bat: MSBC75.
Carter
Does Marucci make a -5 31' CAT 6 or CAT 7 certified to USA?
CMI
Marucci does not make any USA bats currently. They only make USSSA youth models like the 2017 Marucci CAT 7 Senior League Baseball Bat: MSBC75.
Cameron
My son is 12 years old, 5'9" 225 lbs. and hits it out of high school ballparks already, should he be using a 33/30 or 32/27?
Brox
Senior league, or USSSA bats, are allowed to perform at a higher level than BBCOR certified bats, so I would suggest swinging a 32/27 2017 Marucci CAT 7 Senior League Baseball Bat: MSBC75 until he is required to make the switch to the -3 BBCOR bats.
Logan
My son(13)is 5'4'' 115, what bat is best for his size?
Ryan
Based on your sons height and weight we would recommend a 31"/26 ounce 2017 Marucci CAT 7 Senior League Baseball Bat: MSBC75.
Carter
Is this a BBCOR Bat?
WaltTen
No, "Senior League" is a term used to describe a USSSA certified bat for kid pitch below the high school level. Look for the term "BBCOR" in the title of a bat to indicate that certification. All BBCOR bats are a -3 drop.
Kyle J.
What is the biggest difference between the Cat 7 MSBC75 and the Cat 6 MSBC65?
Andy
Marucci introduced a new alloy for their bats when they made the Cat 7 that isn't used in the Cat 6, so that is the biggest difference.
Kyle J.
I do not see the BPF 1.15 stamped on the bat based on the pictures I see. Where is the stamp?
C.H.
The USSSA 1.15 BPF Stamp on the 2017 Marucci CAT 7 Senior League Baseball Bat: MSBC75 is located on the middle of the bat right above the grip. If you take a look at the 4th picture listed on the website you can see that stamp.
Carter
Is the CAT 7 an end-loaded bat or is it balanced?
steve
The 2017 Marucci CAT 7 Senior League Baseball Bat (MSBC75) will feature a balanced swing weight.
Taylor
Is the -5 significantly different from the -8? I"m 5"4" tall and 110 pounds. Can you feel the difference?
George
Yes, most players will be able to feel the 3 oz difference when going form a -8 to a -5. It affects some players more than others however.
Kyle J.
Does this bat come in a 2 3/4in?
kevin
Yes, if you are wanting that version, check out the 2018 Marucci CAT 7 -10 Senior League Baseball Bat: MSBC7X10.
