Its precision-balanced barrel provides a lower M.O.I. nd balanced feels that makes it easy for any style of hitter to enjoy their personal best results.

Pros: Bought the 29/19 for my son. I also have the CAT 7 29/19, which is a great bat! The CAT 8 has a more gradual taper giving it more surface area. The CAT 8 is just a tad bit heavier feeling than the CAT 7, but you would have to really be trying to notice the difference to tell. We Love the barrel! As far as size and taper, it fits between the old green Hex bat and the CAT 7. The sweet spot is insane! Really big sweet spot. Ball speed feels about the same as the CAT 7, but with a larger sweet spot. The bat looks good and should be durable.
Pros: Got a 29/19 drop 10 Cat 8 alloy for the grandson. Used first day in travel ball practice. Good pop and distance right out of the wrapper. No complaints of any sting. All the kids like the look and results. Buy it!
Pros: Bought a 29/19 for the grandson and he loves it. Really good pop and distance with his first few swings. We like the sound when the ball hits the bat. NO complaints of vibration after 2 weeks of practice! Worth the price. Get one!
Cons: All the kids on the team like it and want to use it.
Pros: So, I am not one to spend much time on a computer, but I do feel that I owe the Dad's out there who are looking for the right bat that enhances your son's ability to reach his top performance. Well Dads, search no further....this is the bat that will take your son to the next level.
We have been Marucci loyalists for the past 3 years. We have put away the Eastons, and the Louisvilles since he started swinging his 18/28 Hex Alloy bat thru his 8U, 9U, and 10U seasons (Great Bat!). Just last weekend, we took it out to the ballpark to hit balls to see if he can put it over the outfield fence. He was line driving them, but either one hop or two hops into the fence.
Well, it was now time for a new bat to kick off the 11U season.I read the reviews on Just Bats...and ordered the 19/29 Cat 8. Ordered it and we hit the field this Saturday morning. I pitched first two pitches, both one-hop over the fence. The third - he went YARD!!!! We have officially retired his Hex Alloy.
Cons: NONE - CAT 8 ROCKS...looking forward to the fall season!!!
AFTER OUR RESARCH...THE WINNER IS
Pros: For the last 3 yrs we have watched kids hit with bats and have looked at reviews and have bought and played with Combat Vigor, Rawlings Velo, and Adidas Aeroburner Alloy. My son loves all of these with the Aeroburner being the hottest...until now. The Cat 8 is a solid notch better and my sin smiles ear to ear. He is 12 and a leadoff contact hitter of thinner size with a great swing. This bat hit on the sweet spot smokes the ball. Low vibration to hands. Great bat. We bought 30/20 size. Worth the price. This is the priciest bat we have purchased but priced better than other brands.
Cons: Light color scuffs up easily but can be cleaned.
Pros: Bought this Bat for my 10yr old , playing in his first travel ball season. He loves it!
** balanced feel to the bat
** no vibration on the hands
** hot out if the wrapper
**great price point
** bat looks great
Pros: Previously bought the F5, which was a great bat (especially) for the price. Decided to spend a little more for the next bat and went with the CAT8. While the F5 definitely has good pop, the CAT8 seems to just a bit more. Where this has seemed to translate is in actual games where my son seems to be generating more pop on balls to the gaps. Also, from what I've seen, my son is getting less sting from this bat that the F5 when it's not squared up off the barrell. In summary, the F5 was a great bat (especially for the price), but the CAT8 seems to be worth the additional price. For what it's worth we've had nothing but great reviews for Marucci.
Great Bat, FLAT SPOTS On 2 Bats Already
Father of a Cat Crusher
Pros: Pop for days, balanced swing weight, the bat just begs to hit hard laser beam gappers! For a one piece aluminum there is virtually zero sting on mishits which is pretty amazing on it's own.
Cons: My son (75 pound 11 year old) has already dented 2 of these. The first one was after 1 tournament and the second one was after 2 tournaments. He doesn't use them for BP or even warm ups, GAME SWINGS ONLY! Makes zero sense. I would suggest if you have this bat to roll it through your hand, you can't really see the flat spots but you can certainly feel them. Now I have to send this one into Marucci and wait. LAME
Pros: Composite bats have a brief window where they are exceptional. The Marucci is durable and reliable. The ball jumps off my son's bat as well as it did when his Zen was broken in and before it broke. It's also less expensive which is appreciated. May son loves it.
Cons: None so far. It is very loud in an indoor cage, which the kids prefer.
Pros: My son's entire 8U East Cobb team uses this bat. Amazing pop, we're seeing 1-1.5mph higher exit velocities (Hittrax) with this bat over the Cat7 and definitely higher EVs with this over anything else in the category. We also own the Cat Composite (more expensive) and maybe it's not broken all the way in yet, but still the highest EVs with this regular alloy Cat8. You're costing your son some performance if you buy him anything else.
Cons: Not quite as big of a barrel as the Cat Composite, slightly less forgiving on miss-hits, but more power so far.
Pros: This is a great bat right out of the wrapper. Tons of pop and awesome sweet spot. The grip is super sticky, but it will wear off once it is rolled around the batter's box a few times. My son has been hitting this every night for the past 2 weeks and he still has a smile when he crushes the ball. He plays for a travel team and most of the older players and showcase players all have this bat (plus a few others), but I can say that all of them grab this bat first.
Cons: My only complaint is that I didn't get the Cat 7 last year.
Pros: Bought this for my 11 year old son. He absolutely loves it. He said he loves the feels of the bat. I can see that this bat has more pop then his other bat. I wasn't sure if the handle was really going be a big difference with the vibration but my son said he hasn't felt any vibration yet and this is coming form a kid that ALWAYS had to have the rubber knob for vibration, he has not used it with this bat so far.
Pros: My son is 9 soon to be playing 10u travel this spring. Purchased this bat about one month ago so no real game situations yet. However, he is absolutely crushing this ball with his instructor and at indoor practice facility with his team. He says he loves this bat. One of his teammates has already asked to borrow it at practice
Pros: This is my first time reviewing a bat. My son is on a 12u travel ball team in Tampa FL. We recently purchased this bat and the first weekend my son used it he hit his first Over the fence HR. After my son hit his HR a few other kids used it and another kid hit his first HR. Our team now has 4 of these bats in different sizes and weight. Buy it. You will not regret it.
Pros: This bat has made all the difference. We bought another well known bat also about 280.00 and all he got out of it was pop ups. Since he has started using this bat he was instantly his favorite. We will ALWAYS invest in a Marucci!!
Pros: This bat is hot straight out of the wrapper. Big 8yo son (59" & 100lbs) was moving up from Easton Ghost X Hyperlite (29/17) to something a bit bigger (30/20). We looked at and tried almost all high end bats on the market, but he felt most comfortable with the balance of this Cat 8. The Ghost X was a composite so I was worried about stinging on mishits. After many cage sessions, he has not had even one stinger. He raves about how much better it feels than his Ghost X. Sound is just right and he now has more confidence at the plate than ever before, which is half of the battle for travel ball at his age. Same kid, same swing, and balls are traveling significantly farther than before. It is not a cheap bat, but at this price point, I would argue that you won't find a better bat. He has recommended this bat to everyone who is willing to listen. No issues with durability so far, but just getting started on the season, so only time will tell.
Pros: Good cool weather bat . Bought the bat because of cool weather affecting his composite bat. In season opening double header he went 5 for 7 with a walk off dinger and 7 rbi’s. Don’t think the homer would have carried in the cool weather with a composite bat.
Cons: Don’t know yet. That’s why I gave it 3 stars for durability. My grandson has only used it for one bp and two games.
Cons: After 10 swings with official league baseballs the bat has at least 3 dents. One is a flat spot. My son is a 95 lb 11 year old and is pretty disappointed. I don't normally do bad reviews, but I got this bat because of all the great reviews. I know either just bats or marucci will make it right, but another of these bats will not be good enough.
Marucci Cat 8 Gold Standard for 9u
Pros: Best Pop out of any USSSA bat on the market. Our 9u team has used them all and we still use cat 8 and cat 7 exclusively
good grip and padding on handle
boys like the way it sounds on a hit over CF zen
fit and finish is outstanding
Cons: grip tape starting to come loose after a few weeks, but we will replace with lizard skin before tournaments this summer anyways.
Pros: This bat actually has pop. My son has 3 bats in his arsenal. A CAT-7 (about $180), a Zen($350), and this Cat-8. Both the other bats are decent, but the Cat-8 is worlds above both the others and priced about in the middle. Since this bat was bought half the kids on the team hit with it. The sweet spot is almost from the taper to the end. Definitely the best bang for the buck.
Pros: Huge pop, very low vibration, excellent balance. After 5 seasons with Easton, and 2 broken bats, we tried the Marucci. Wow. tremendous pop. My son loves it, and now a ton of kids on the team have started to share it. Glad we bought it.
WHY WOULD YOU BUY ANYTHING ELSE....SERIOUSLY!
Pros: My son used at -10 30/20 for age 13 Select. By the end of the season he had cracked it but it still performed even cracked. Marucci replaced it and we are on to next year. I research and buy bats for my son to try. By far this bat not only has best sweet spot, low vibration and best pop of anything in this price range or higher. If Marucci keeps this up I don't need to research or buy anything else. Love this bat. Don't change anything on quality or price Marucci, you are cornering the market. Thanks.
Cons: White wears rough, wish it was red like the Cat 6.
Pros: Power out or wrapper, balance, and huge sweet spot! My son is 8 and plays 9u travel ball. He swings the 28-18 and consistently hits solid line drives. He is on the small side but because this bat is so balanced, his contact has improved. I coach the club team and Nearly my entire roster swings CAT8’s
Pros: Tested and unparalleled pop. I have HITTRAX and have tested this against other bats and the exit velo and distance is a huge difference. I’ve been buying since the CAT5 series and never find a better bat. Always searching and testing but never find one. This bat had a 6 mph higher exit velo than the new 2020 axe avenge and had a max distance of 49 foot farther. My son probably has over 12k swings on this bat over the last year. It’s still hot and hasn’t lost pop.
Cons: Vibrates pretty badly. Get a lot of stingers compared to other bats. Mostly off higher velo.
Pros: My son loves this bat has alot of pop.
He does get hand stinger once in a while. Otherwise the bat is awsome
Cons: My sone has over 500 swings all practice the bats does have some small dents now. We have another cat 8 to use while we send the dented one back for warranty. Mariucci will only warranty the bat once .
Pros: Just got this bat for my 11 year old playing his first year of travel ball. After using a USA baseball bat for the last 3 years, this bat was very much appreciated. It has great pop and a nice big sweet spot. Vibration is minimal even for balls hit off the end or the handle. The bat also has a distinct loud “ping” and teammates usually take notice when you hear it. About half of the players on my son’s team use the CAT8, so this is clearly a very popular bat.
Cons: This bat has been used quite a bit in just 2 weeks as we have a batting cage at our house. There are a couple of small dings and the bat has only been used to hit real leather baseballs. I’m not sure about the durability, but time will tell.
Solid Bat - No Worries of Cracking
Pros: Bat is balanced and has pop. No worries of cracking like composite bats. Third purchase in the CAT family the last couple of years. Each bat purchase was for different size and performance is repeatable. Players on team swing bat with confidence.
Pros: My 10 year old son absolutely LOVES this bat! The majority of his travel ball team has a marucci bat too. My son says the bat does not vibrate in his hands when he bats. He loves the length and weight.
Pros: The ball seems to jump off the bat compared to USA bats and even other USSSA bats, ie, distance in hits has been 10-20 feet farther compared to other USSSA bats. It seems durable and solid so far. Need a little more time to gauge true durability. Swing is balanced and player really likes it. No complaints regarding vibration. Went with a 29” for an average-sized 9 year old even though usually uses a 28”. The extra length hasn’t been an issue.
Unfortunately as of right now, we are only aware of the 2 3/4" version of a -10 like this Marucci CAT 8 -10 USSSA Baseball Bat: MSBC810 being manufactured by Marucci.
Which bat will have a longer or larger barrel the Marucci cat 8 -10 or the Marucci Cat 8 -8? Both in a 29 inch 2 3/4 barrel.
If you order the Marucci CAT 8 -10 USSSA Baseball Bat: MSBC810 in a 29'' and a -8 in the same 29'' the barrel will be the same exact length.
When will the shorter lengths be released?
The Marucci CAT 8 -10 USSSA Baseball Bat: MSBC810 was released in sizes 27 - 31 inches. We currently only have 30 and 31" available in stock. You can add your email address to our notifications for the smaller sizes and you will be notified when that size is back in stock.
When do you expect to get the 28 inch drop 10 in stock?
Typically speaking, it takes about 2-4 weeks after we run out for the manufacturers to provide us with more inventory. However, considering the Marucci CAT 8 -10 USSSA Baseball Bat: MSBC810 just released that time frame may be shorter than that.
Which bat gets to the 2 3/4' diameter faster, the 2018 cat 7 (-10) or the 2019 cat 8 (-10)?
Both the Marucci CAT 8 -10 USSSA Baseball Bat: MSBC810 and the 2018 Marucci CAT 7 -10 Senior League Baseball Bat: MSBC7X10 will have very similar barrel lengths and offer extremely large sweet spots.
How does the pop compare to a high end composite bat such as the 2019 Zen?
The performance of the bat will be very equal in the Marucci CAT 8 -10 USSSA Baseball Bat: MSBC810 as the 2019 CF Zen because of the USSSA BPF 1.15 Certification.
Is this bat approved for 11u baseball?
This bat has the 1.15 BPF USSSA stamp for travel baseball. It does not have the USA stamp for Little League play.
Is the 2019 Marucci CAT 8 - 10 approved for coach pitch base ball?
The Marucci CAT 8 -10 USSSA Baseball Bat: MSBC810 can be used in coach pitch baseball as long as the league follows USSSA.
What is the difference in the Marucci Senior League Cat 8 and the Marucci Junior Big Barrel Cat 8?
The Marucci CAT 8 -10 USSSA Baseball Bat: MSBC810 will be intended to be used in all kid pitch leagues. Any Junior Big Barrel bat is constructed to be used for coach/machine pitch baseball and should not be used at any velocity above 40mph.
I am looking at one of the new cat 8 bats for a power hitting 10u. Are there advantages to the different types of the cat 8's?
The differences between those models will be similar to the difference in their constructions. The Cat 8 Composite will be a multi-piece bat that will require a break-in period and should be the most comfortable on contact. The Cat 8 Connect is a hybrid bat utilizing an alloy barrel and composite handle. This will provide a traditional alloy feel on contact while reducing the overall vibrations felt by the hands. Lastly, the 2019 Marucci CAT 8 -10 USSSA Baseball Bat: MSBC810 will be a one-piece alloy bat that will be stiffer on contact and traditionally more beneficial for a power hitter.
If I order the bat through your company and there are any defects in the bat such as bending or cracking within a year. Do I send it back through your company?
The Marucci CAT 8 -10 USSSA Baseball Bat: MSBC810 comes with a 12-month manufacturer's warranty. If your bat becomes defective within a year from the date of purchase, the warranty claim would be handled through Marucci directly.
However, we are happy to provide instructions, contact information, and an UPS shipping label as an assistance to our customers.
My 9 year old plays travel and currently is using an Easton Beast -10 28in/18oz. He is 4'8 and weighs 67 pounds. I am planning on getting him a Cat 7 or Cat 8 for the 2019 season. Do you recommend that I move up to a 29 inch bat for him or stick with the 28 inch. Is there a certain guide you go by to know when to move him up to a longer bat? T
With the size specifications you listed for your player, we would suggest the Marucci CAT 8 -10 USSSA Baseball Bat: MSBC810 in 29 inches. The thought process being that he will continue to get taller and stronger.
You can test out our Bat Coach, https://www.justbats.com/bat-coach/ to help determine the right length of bat for your player.
Does this bat have more pop than the DeMarini 2018 CF Zen?
Unfortunately it is impossible to compare the pop of the Marucci CAT 8 -10 USSSA Baseball Bat: MSBC810 to that of the 2018 DeMarini CF Zen as this is more opinion based. The Marucci CAT 8 -10 USSSA Baseball Bat: MSBC810 has shown better durability based on customer feedback compared to the CF Zen.
What's the difference between the -10 CAT 8 27” inch bat and the junior barrel CAT 8 27"?
The difference between this Marucci CAT 8 -10 USSSA Baseball Bat: MSBC810 and the Junior Big Barrel model is that the Junior Big Barrel bat is made for use in coach and machine pitch, while this bat it to be used at kid pitch levels.
Would this bat be okay for a 7 year old in coach pitch?
The Marucci CAT 8 -10 USSSA Baseball Bat: MSBC810 would be a great option for a 7 year old coach player. At his age, I would suggest the 27" 17 ounce Marucci CAT 8 -10 USSSA Baseball Bat: MSBC810.
My 9 year old son is 72lbs and 4 ft 5" and a contact hitter. Is this a good bat for his size? Length?
Yes, the Marucci CAT 8 -10 USSSA Baseball Bat: MSBC810 would be an excellent option. Furthermore, given his specifications I would recommend a 29" bat.
Is this the bat for someone who play's travel on a 12U team? He's 5'5" and 115 lbs. What length would you recommend? He played last year with a 32" bat and had a 1.011 OPS.
The Marucci CAT 8 -10 USSSA Baseball Bat: MSBC810 I would imagine will be one of the top bats of for travel baseball. I would recommend sticking at 32'' length based on his height, weight and success that your player has had.
My son is 4' 10" and 110 lbs. He is 12 years old and I want to get him a CAT 8 that he can use for fall ball 2018, spring and summer 2019. He has a 30" Cat 7, drop 8 now and loves it. Should I get him a drop 10 or drop 8 Cat 8; in 30 or 31 inch?
I would recommend going with the 30'' in a drop eight for the Marucci CAT 8. The Marucci CAT 8 -10 USSSA Baseball Bat: MSBC810 could be a little light with your son swinging a -8 already and doing well with it.
How does this compare to the Combat Maxum? My son uses the 2018 Combat Maxum (29/18) and has used the Cat 7 (29/19) a few times. Ball seems to jump off the Cat 7 more, am I seeing this right? He will be playing 11u next spring and want to make sure he has the best bat for him. He is 4’7 and about 85 lbs.
The biggest difference is the material of these two bats the 2018 COMBAT MAXUM -11 Senior League Baseball Bat: SL8MX211 is a one piece composite which allows for reduced vibration. Composite bats do require a bit of a break in period and you see their performance increase.
While the 2019 Marucci CAT 8 -10 USSSA Baseball Bat: MSBC810 is a one piece alloy and features a multi-variable wall design that creates an expanded sweet spot and thinner barrel walls that are forgiving after off-centered hits. Alloy bats are ready for play right away.
You may indeed see better performance with the Cat 7 due to the added weight of a -10 versus the -11. For a player of his size specifications, we would suggest either a 29" or going up to a 30" -10 or -8 bat, depending on his strength. We recommend a player swinging the heaviest bat they can for best overall performance.
Whats’s the difference between this model and the Jr version?
The Marucci CAT 8 -10 USSSA Baseball Bat: MSBC810 is constructed for higher velocities (kid pitch) compared to the Junior Big Barrel which is constructed for coach/machine pitch (max ~40mph.)
Can this bat be used for coach pitch? My son plays 8u coach pitch but will start kids pitch next year. What bat do you guys recommend?
The Marucci CAT 8 -10 USSSA Baseball Bat: MSBC810 is designed for kids pitch but can certainly be used for coach pitch as well. If your son will be playing kids pitch next year then the Marucci CAT 8 -10 USSSA Baseball Bat: MSBC810 would be a great bat to get now as well as to use down the road. The one-piece alloy design features a balanced swing weight feel and the AV2 knob design helps eliminate almost all of the vibration a player would feel from an off-centered hit.
Can this be used in PONY league?
PONY baseball requires the use of either a USA or BBCOR certified bat. With the Marucci CAT 8 -10 USSSA Baseball Bat: MSBC810 being USSSA certified, it will not be legal for play in PONY leagues.
My son is 4'7", and maybe 70 lbs. He swings his teammate's CAT 7 28/20 and CAT 8 29/19 well enough. Would getting a 30/20 and choking up be a good idea?
Based on his height and weight, the 29'' is the suggested size for him. He would probably be able to get a 30'' in the Marucci CAT 8 -10 USSSA Baseball Bat: MSBC810 and use it just fine.
Is this bat end loaded?
No, the Marucci Cat 8 is a balanced model.
Thoughts about the correct size. My son is 9, turning 10 next June and I'm torn between the 29/19 and 28/18. He's 54" tall and weighs 68 lbs. He used a teammate's CAT 7 27 inch and I was going to go to the 29, but it seems a lot heavier. I'd like the bat to at least last a year. Thoughts about going to a 28 or 29 inch?
With the size specs provided, we would suggest the Marucci CAT 8 -10 USSSA Baseball Bat: MSBC810 in the 29" / 19 oz option. The bat may require some practice; however, your player will only continue to get stronger. Your player would outgrow the smaller size fairly quickly.
What is the difference between the -10 Cat 8 and the composite -10 Cat 8? The one-piece is about $120 less than the composite.
The Marucci CAT 8 -10 USSSA Baseball Bat: MSBC810 is constructed out of alloy material, which is less expensive to manufacture than composite materials. Alloy will conduct more vibrations, but also be hot out of the wrapper when compared directly to composite.
Which is better for 10U CAT 8 alloy or composite?
In my opinion, I would proceed with the alloy model. The reason I lean towards the Marucci CAT 8 -10 USSSA Baseball Bat (MSBC810) is because it will not require a break-in period and therefore your 10u player would be able to utilize it right away.
I am looking at the 28/18 for my 9 Year old and am wondering if this bat has good pop in all weather conditions? We play some games early in the season in 40 degree weather and then play in July in 95 degree weather. If not, please recommend me to one that is better in all weather conditions.
He loves hitting a Marucci
Generally speaking aluminum models such as this Cat 8 -10 (MSBC810) perform better in colder weather and are a bit more durable than composite models in cold weather (below 50 degrees). This would be an excellent option for you in my opinion.
What material is this bat?
The Marucci CAT 8 -10 USSSA Baseball Bat: MSBC810 is made from alloy (AZ105).
Can this bat be used in Dixie Youth League play (USA)?
The Marucci CAT 8 -10 USSSA Baseball Bat: MSBC810 would not be legal for USA certified play. This bat is only certified for travel tournament play.
Will this bat be available in 2 5/8 barrel?
The Marucci CAT 8 -10 USSSA Baseball Bat: MSBC810 will only be offered with a 2 3/4" barrel diameter.
My son is 9 and we are looking at the new Cat8. He is in kid pitch, but the bat we found says “Coach Pitch Only” or something like that. The next Cat8 is a Senior League bat and has a smaller sweet spot. Will the Coach pitch bat hold up?
To answer your last question, no the coach pitch model would not hold up to the rigors of a kid pitch season. Furthermore, most leagues would not even allow use of that bat in a kid pitch game. You would want to proceed with the Marucci CAT 8 -10 USSSA Baseball Bat: MSBC810 as it is the correct bat for your player.
Does this bat come with the USA label that is required by a little league? My son is 11 and I want to make sure I get the correct bat. Is there a difference between a youth big barrel and a regular barrel?
No, this bat does not have the USA certification stamp. It has the USSSA 1.15 BPF stamp as indicated by the "USSSA" in the title. For a USA bat, you can use the "Approved By" search filter on our site and select "USA Bat" to be shown bats certified for Little League/Babe Ruth youth use. The term "Youth Big Barrel" simply refers to a youth bat with a barrel larger than 2 1/4", and intended for kid pitch use.
What is difference between this and the Louisville Omaha 519?
The main difference is that the Marucci CAT 8 -10 USSSA Baseball Bat: MSBC810 offers an anti-vibration know making contact much more comfortable for the player. This is not common for one-piece alloy bats as they typically create sting in the hands on poor contact.
What is the difference between the MSBC810 and the MJBC88?
The difference between the Marucci CAT 8 -10 USSSA Baseball Bat: MSBC810 and the Marucci CAT 8 -8 USSSA Baseball Bat: MSBC88 is the drop weight of the bat. The drop weight is the length to weight ratio of the bat. The MSBC810 features a -10 length to weight ratio so sizes will be 27" 17oz, 29" 19oz and so on. The MSBC88 features a -8 length to weight ratio so sizes will be 28" 20oz, 29" 21oz, and so on.
Which bat would you consider to be better for all around performance and power, the Marucci Cat 8 29/19 or the Marucci Hex Connect 29/19?
While performance between the two bats will be the same (if the bat is stationary), the stiffer one piece construction of the Marucci CAT 8 -10 USSSA Baseball Bat: MSBC810 typically benefits a power hitter, while the two piece fully composite construction of the Marucci Hex Connect Senior League Baseball Bat: MSBHCX10 offers a larger hitting surface and is more forgiving on off center hits.
Will they weigh close to what is stated?
Virtually any bat on the market will weigh 1-1.5 oz heavier than the listed amount. A test model that I just weighed of this Marucci Cat 8 -10 came in at .7 oz over the listed amount, so it seems to be more accurate than other models at least.
I'm looking for a great USSSA bat for my son. Is this the one I should get, or are there others that we should look at?
Currently, the Marucci CAT 8 -10 USSSA Baseball Bat: MSBC810 has been one of our most popular and highest rated USSSA bats out there. It would be hard to suggest another that would be better!
We just received this bat. We have the 30 inch -10.
I ordered this bat for my 10 year old playing USSSA. It has the USSSA stamp on it but it also says ‘Senior League”.
Is this approved for USSSA youth?
Yes, this bat is approved for USSSA play. "Senior League" is just another common term for USSSA play, and references kid pitch leagues.
What is the difference between the MSBC810 vs the MJBBC8?
The MJBBC8 is a "Junior Big Barrel" bat, which means it is designed for machine pitch and coach pitch, and won't hold up very well in kid pitch leagues. The MSBC810 is the kid pitch bat.
My son is 4-11 and weights 78 pounds. What size bat do you recommend? He is currently using a Hex Alloy 29/19, would he see much benefit with the cat 8?
Based on your player's height and weight, I would suggest moving up to a 30" length. The Marucci CAT 8 -10 USSSA Baseball Bat: MSBC810 does offer an improved alloy material and larger sweet spot than the Hex Alloy.
So I purchased this bat, a 30'' 20 oz for my son for Christmas from you guys. He loves it, great pop, great stick! After 2 months of cage work it's looking used! Is there any way to safely clean the barrel?
There is a good way to clean ball marks off the barrel of your Marucci CAT 8 -10 USSSA Baseball Bat: MSBC810. I would recommend rubbing a new tennis ball in a circle motion on the ball marks, this will help clean the ball marks and will not damage the bat.
Does Cal Ripkin League allow this bat for the 11 year old age group?
No, the Marucci CAT 8 -10 USSSA Baseball Bat (MSBC810) would not be allowed in the Cal Ripken League.
The Babe Ruth/Cal Ripken League requires the use of USA certified bats and because the CAT 8 features the USSSA bat certification, it would not be allowed.
I have a question on bat size. My son is currently 11, almost 12 in a few months, he’s about 5’6'' and weighs 135-140 lbs. He’s debating on getting a 31'' since his current 30'' is feeling “small.” Can I get some input?
Based on your son's height and weight, the best size to get the Marucci CAT 8 -10 USSSA Baseball Bat: MSBC810 in would be a 32''. However, if he wanted to just move up an inch to make the transition a little easier, he could definitely do that without a problem
marucci cat 8 we saw in store was labeled senior
we want the cat 8 usssa in 31/21
why does the store bat at say senior? (NP)
Harry, thanks for the question. Senior League is an older term to refer to USSSA, kid pitch baseball. The terms can be used interchangeably. They are the same models. (NP)
Does temperature affect bat, is there a certain temperature it shouldn't be used?
The Marucci CAT 8 -10 USSSA Baseball Bat: MSBC810 features an alloy barrel. Unlike composite barrels, alloy options do not experience durability concerns in colder temperatures.
Does the Marucci CAT 8 come in a 32 inch -10?
The largest option of the Marucci CAT 8 -10 USSSA Baseball Bat: MSBC810 would be 31 inches. To get a 32" Marucci Cat series, you would have to move towards a -8 or -5 option.
What is the difference between the MSBC810 and the MJBBC8?
The Marucci CAT 8 -10 USSSA Baseball Bat: MSBC810 is intended for machine and kid pitch. The Marucci CAT 8 -10 Junior Big Barrel Baseball Bat: MJBBC8 is only intended for coach pitch or tee ball.
I'm having to send a CAT 8 back for warranty claim as the bat we have has dents in it. Son has just hit baseballs for practice and games with it the last 3 months. He does hit the ball with authority but has JustBats seen any issues like this with the CAT 8?
We have not heard of any issues with the Marucci CAT 8 -10 USSSA Baseball Bat: MSBC810 with regard to durability issues.
What is the thickness of the grip that comes on this product from the factory, 0.5 mm or 1 mm?
To our knowledge, the Marucci CAT 8 -10 USSSA Baseball Bat: MSBC810 features a 1 mm thick grip tape.
Can the Cat 8 be used in Cal Ripken 10u baseball?
This particular model, the Marucci CAT 8 -10 USSSA Baseball Bat: MSBC810, cannot be used in Cal Ripken. They require a USA stamp. However, you can use the Marucci CAT -10 USA Baseball Bat: MSBC10USA.
What is the difference between the Marucci CAT 8 and the Marucci Posey28 Pro Metal?
I love marucci
The only difference between the Marucci CAT 8 -10 USSSA Baseball Bat (MSBC810) and the Marucci Posey28 Pro Metal -10 USSSA Baseball Bat (MSBP2810S) is the colorway and cosmetic design.
What is the difference between the MJBBC8 and the MSBC810?
The Marucci CAT 8 -10 Junior Big Barrel Baseball Bat: MJBBC8 is constructed for younger players in machine or coach pitch. This option is not meant to meet pitching velocity over 40 mph. The Marucci CAT 8 -10 USSSA Baseball Bat: MSBC810 will be for your intermediate youth players in kid pitch.
What’s the difference between this bat and the Jr big barrel? I’m looking for a 27/17 bat.
The Marucci CAT 8 -10 USSSA Baseball Bat: MSBC810 would be used by those players who are playing in a kid pitch league. A Junior Big Barrel bat will be used by players between the ages of 6-8 who are in coach pitch leagues. The reason for this is that a Junior Big Barrel bat can only withstand velocity up to about 40 MPH.
Should I go with the 1.00 mm or 1.75 mm diameter grip for an 11-year-old?
Grip thickness is a purely personal preference decision, so it's difficult to say. Generally speaking though, 1.00 mm will be more common than 1.75, especially for younger players with smaller hands, so I would lean towards that option.
Why does it say "Senior League" on its side? Just confirming this is a USSSA bat for my 10 and 11 year olds!
Senior league is another term used for USSSA bats. The Marucci CAT 8 -10 USSSA Baseball Bat: MSBC810 is USSSA certified.
11u 4'9" and 115 lbs. Needs a great bat with pop. Swings -10 31/19 old COMBAT and loves it. Any recommendations? Exit velocity avg. is 58 MPH.
The Marucci CAT 8 -10 USSSA Baseball Bat: MSBC810 has shown to be both a highly durable and performing bat according to those that have been using it. Per your son's height and weight, we would recommend this bat in a 30 inch.
CAT 8 vs Rawlings 5150 USSSA. What are the advantages of CAT 8?
The Marucci CAT 8 -10 USSSA Baseball Bat: MSBC810 will feature more vibration control when compared to the Rawlings 5150. This is due to the 2nd Generation AV2 knob that Marucci features on the CAT 8 series. Other than that, both bats are one-piece alloy models with balanced swing weights.
What is the difference between this one and the junior big barrel version of this bat? I notice the price but wanted to know the details. My son is 8 and is playing coach pitch this year and want to make the better decision for him.
The Marucci CAT 8 -10 USSSA Baseball Bat: MSBC810 is constructed for kid pitch. Its true weight will come in a little heavier. The junior big barrel option is not constructed to withstand more than coach/machine pitching of 40mph.
My son had the bat for 3 days, hit with it for the first time, and the bat broke in half. Someone mentioned this was a new problem with the Cat 8? Is that true?
I actually have not heard of a high amount of durability complaints on the Marucci CAT 8 -10 USSSA Baseball Bat (MSBC810). That being said, odd things can happen on an isolated basis. If your bat was purchased within the past 12 months, you would still be under the 12 month warranty from Marucci. I would recommend reaching out to Marucci and organizing a return for replacement if it is under the 12 months from the purchase.
My son will play 12U travel next year. Currently uses a 30 inch drop 10 USA bat, 2 5/8" barrel. We want a CAT 8. drop 10 but unsure if we should go to 31 inch or stay with 30. He's 4' 11'' now and 90 lbs. in 3-4 months he could use a 31 inch but will the bat last 2 years?
With the player specs listed, yes, your player may be able to move up to a 31" of the Marucci CAT 8 -10 USSSA Baseball Bat: MSBC810. However, something to consider, 13U USSSA play regulates players to use a -8 bat or heavier. This -10 will only be good for your player until he moves up to 13U play.
Would this be a good/comparable replacement for the Hex Alloy 2 (MSBHA2X10 with the AZ105 alloy)? Other than cosmetics, is there any difference between the CAT 8 and the newest Posey 28? All my research has said no, but I want to be sure (he is a catcher and loves Posey, so if they are the same.....)
The Marucci CAT 8 -10 USSSA Baseball Bat: MSBC810 would be an excellent option to consider for someone that has used the Hex Alloy 2 previously. Both of these bats will feature the same AZ105 alloy. As for the CAT 8 and the Posey28, the barrel taper is slightly different on the Posey28 and this difference will give the two bats a different balanced feel. Which one is ultimately more balanced could be debated as it would be more based on personal opinion than anything else.
What is the difference in the CAT 7 to the CAT 8?
The Marucci CAT 8 -10 USSSA Baseball Bat: MSBC810 features a new alloy (AZ105) and an upgraded version of the AV2 anti-vibration knob.
Is this bat end weighted?
No, the Marucci CAT 8 -10 USSSA Baseball Bat: MSBC810 will feature a balanced swing weight.
Is there any difference between the black and white cat8 (outside of the obvious color)?
The Marucci CAT 8 -10 USSSA Baseball Bat: MSBC810 and the Marucci CAT 8 -10 USSSA Baseball Bat: MSBC810BG are the same bat except for the color.
What is the thickness of the tape .5mm, 1.0mm or is it 1.75 mm? Thanks for the information
This bat will have the standard 1.0mm grip tape.
What is the actual weight of the 27/17?
The Marucci CAT 8 -10 USSSA Baseball Bat: MSBC810 will weigh roughly 1 ounce more than the listed weight.
My son plays 12u travel baseball and needs a USSSA bat. Last year he used an Easton Mako 2 1/4 barrel 31” 20 oz. He’s grown in the last year and is 5’5” and around 170 pounds. Thinking of switching to the big barrel Cat 8. We are pretty sure he needs to go up to a 32” just want to make sure though and not sure what weight to go with. He is a strong power hitter. Thanks!
Based off the information provided, I would suggest the 32" 27 oz.
Does it have good balance when you swing?
Yes, this is considered a balanced model.
Is this bat allowed for play in Cal Ripken or JBO baseball?
The Marucci CAT 8 -10 USSSA Baseball Bat: MSBC810 cannot be used in Cal Ripken or JBO as the Cal Ripken & JBO leagues requires a USA stamped bat. The USA model is the Marucci CAT -10 USA Baseball Bat: MSBC10USA.
Is this bat legal for New York State Little League?
No, the Marucci CAT 8 -10 USSSA Baseball Bat: MSBC810 cannot be used in Little League. The only bat that Marucci has that is USA approved is the Marucci CAT -10 USA Baseball Bat: MSBC10USA.
My son is 9, 4ft 5 and 73 lbs looking for a new bat. What size do you recommend?
I would recommend going with the Marucci CAT 8 -10 USSSA Baseball Bat (MSBC810) in a 29" & 19 oz.
I bought this bat at Dicks Sporting Goods for my son, he's in Triple A. Can he use this bat? The salesman didn't say anything but I need to know because the question came up at batting practice.
This Marucci CAT 8 -10 USSSA Baseball Bat (MSBC810) is approved for USSSA play. Typically, Triple-A uses USA approved bats, which leads me to believe this bat would not be legal. I would suggest double-checking with league rules just to make sure!
