Marucci CAT 5: MSB2 Senior League

by Coach Buss in WA - May 09, 2011

Pros: Bought this bat due to the new bat restrictions being placed at all levels and figured it would be a great transition bat for my 13 year old to BBCOR bats. He found it to have great balance, characteristics of both a metal bat for durability and a composite bat for great pop in the sweet spot. He's a line drive hitter but has hit a few bombs to the deeper fences. Great bat for a contact hitter.

Cons: Sweet spot is not as big as the full composites. (But is still a great bat or equal when compared to more expenseve bats!) Not a well known bat so getting full "buy in" from a youth is important when all his friends are swinging those more expensive Combat, Easton or Demarini bats.

Review Summary

Marucci CAT 5: MSB2 Senior League
4.7 based on 40 ratings. 40 user reviews.

The MSB2 features the USSSA 1.15 Stamp and is approved for play in 2012! Until last season, Marucci was always known for their wood bats. Then the CAT 5 burst onto the scene and became one of the top aluminum bats on the market. This year, Marucci raises the stakes again with unbelievable new technology. Through endless field testing with the top players in America, Marucci discovered that vibration in the top hand is the most common complaint amongst amateur baseball players. Marucci has acquired a patented new anti-vibration technology that blows the competition away. They hired noted bat scientist Dr. Daniel A. Russell to do some lab testing against the top bats on the market. The results were shocking. He found that the vibration dampening rate on the CAT 5 is 5.6 times higher than the next closest competitor! For the player, this means that they can step up to the plate worry-free with one thing on their mind; blasting one over the fence! This is literally the smoothest swinging bat ever produced. Experience the difference of this one-piece bat made from the most responsive alloy in the industry. Marucci: Game Tested. Player Approved. The Marucci CAT 5 carries a Full Twelve (12) Month Manufacturer's Warranty. Free Shipping!

Marucci CAT 5: MSB2 Senior League

by marcpark - Apr 05, 2011

Pros: Bought this bat for my son because it was the only bat that qualified for his middle school in my price range. I can't tell you how pleased I am with this bat. He loves it. He has had the best games of his life with this bat. It is well balanced and has absolutely no sting so he does not hesitate to try and smash the ball. His coach says that he swings as if he is hitting a beach ball instead of a baseball. He just steps up and kills it because he has no fear of a sting if he misjudges. Get this bat, you won't be sorry.

Cons: NONE...

by baseballdad - Apr 06, 2011

Pros: My son says he really likes the feel of the bat. It appears to have pretty good "pop" as well.

Cons: Unfortunately, he has only used it a short time and the grip tape is bunching up at the knob. I wish I had a local rep that would repair under warranty. My son can't afford to go without the bat to send it off for repair.

Marucci CAT 5: MSB2 Senior League

by Sweet Bat - Dec 08, 2011

Pros: I bought the 30/22 for my 10 year old. He's tall and strong for his age. He's had it for a couple of months and absolutely loves it. He had been using a -10 Easton, and I was concerned that he'd sacrifice too much bat speed moving to the -8. It hasn't been a problem. The bat is very well balanced; my son gets it around really well; and the ball jumps off it.

Cons: None so far.

by griff - Jan 23, 2012

Pros: My son was sad to hear he needed a new bat due to the recent regulation changes. Right out of the box, he began crushing baseballs. He loves it! It is heavier than his old bat, but the weight is distributed evenly and he actually says that this bat feels lighter. The thicker grip/handle is a big plus. The free shipping allowed me to pay for the 3 day shipping. The bat arrived 1 day early! VERY SATITSFIED.

Cons: none

by LTCTonyV - Apr 18, 2012

Pros: The minute I felt this bat I could feel how well balanced it was. My son (12) told me it felt lighter than his 31/22, its a 31/23. He has had only one game with it so what I can say is it sounds different and the ball comes off with more pop or speed. I would rap this up with you cannot beat the price for this product. We can only see how it holds up! Anyone else I speak with swears by them!

Ask Question

25090

I am a power hitter and I am 5'0", 111 pounds. Would the Marucci CAT 5 or Marucci Black be better?

Power hitters typically prefer a one-piece bat and contact hitters typically prefer two-piece designs. With that being said, the Marucci CAT 5 is a one-piece alloy design that works great for power hitters and the Marucci Black is a two-piece hybrid design that works great for contact hitters. If you are a power hitter, I would suggest going with the Marucci CAT 5.

22995

Is this a big barrel bat?

Yes, the Marucci MSB2 would be considered a big barrel at 2 5/8 inches. For more bat information feel free to contact our customer service at 1-866-321-2287.

21996

I have a 12 year old son, 5' tall, 83 lbs. Looking for right size bat.

Based on his height and weight, I would suggest going with a 30 inch bat. As far as weight is concerned, it is generally recommended to move up an ounce or two each time you buy a new bat. I would probably move up a couple ounces from the bat he is currently using.

21635

I am considering a cat5 for my 8 yr old he is 4ft 9 80 lbs. What is the most solid all around size and make in this brand?

Based on his height and weight, a 30 inch 22 ounce model would be the best option.

20565

Last year, my son used a 31/19 bat. He's 5'6" and pretty strong. I was wondering If I should get him the -8 version?

Moving to a -8 will depend on what feels best to the player. It's recommended to move up in weight each year to help build muscle, creating more power. Have him swing a -8 to see if he feels comfortable and if the bat speed is consistent a -8 will work for him.

20368

is the cat 5 senior league msb2 approved for play in babe ruth league?

Depends on your division. If you're in the 13-15 year old division it is 100% legal. If you're in the 16-18 division, it is not, because you have to use a -3 adult bat in that division.

19776

I am looking for a bat for my 13 year old to use in both USSSA tournaments and Junior Little League tournaments. Would this bat be legal for both? Do you have any suggestions for other bats that are legal in both leagues?

Based on the information I have, this bat would be legal for both. It is an all alloy bat, so it doesn't need to meet BBCOR standards for Junior Little League and can have any drop. It also has the new USSSA stamp making it legal for play in USSSA tournaments as well. Since rules do change from league to league, I would suggest double checking with your league official just to make sure.

18093

is this bat leagal in ussa torniments

Yes this Marucci Cat 5: MSB2 features the USSSA Stamp and is legal for use in USSSA tournaments depending on what barrel size is required for the age your son or daughter is playing in.

17970

Is this bat legal in little league?

Yes. This bat is legal in Little League

17582

Does the bat have the year of manufacture and "approved for pony" per 2012 pony rule changes?

This bat is legal for use in Pony League. It will not have "approved for pony league" printed on the bat, since the barrel size is 2 5/8 inches. Only bats with a barrel diameter of 2 1/4 in are required to have "approved for pony league" stamped on the bat.

17036

Is the Cat 5 approved for USSSA play? Is it stamped with a BPF 1.15 rating?

Yes, the MSB2 does have the new USSSA stamp for 2012. The MSB2 is an all alloy bat with a large sweet spot, durable barrel and has been a popular -5 bat.

15553

14 year old - 5'4" and 110 lbs, I believe that am looking at the drop 5. Have heard conflicting reports about whether or not to look at a 30/25 or a 31/26. Is there much of a difference in these two sizes? Any advice?

You can determine the best size by checking out our size chart at http://www.justbats.com/products/baseball%20bats~youth%20big%20barrel/.

15200

Whats better the cat 5 or the black

Both bats are very good options. The Cat 5 is an all one piece alloy bat and the Black is a two piece bat. These bats have great pop and large sweet spots.

14816

Do you think is better then the rival.

This will be more of a personal preference. Both are good bats.

14306

Our league is not allowing two-piece bats nor composite bats. Is the CAT 5 a composite bat?

No, this is a one piece all alloy model.

13974

14 year old - 5'2" and 100 lbs, likes the Cat5 but we don't know whether to go with -8 or -5 for his final youth/senior league spring season. He needs to work up to -3 for high school summer ball in 5 months. Hit with -8 last spring and wood bats in fall league (which he could handle but not easily). Any recommendations?

You do want to slowly move them in weight as they get older, but you dont want the weight of the bat to effect their mechanics. I would recommend going with the -5, just because it will help prepare him for high school when he gets to a -3.

13842

is this bat 1.15bpf

Yes, this bat would feature the USSSA BPF 1.15 stamp on the bat.

12824

My son hit a 29 19 Rival last year and I am thinking the the 29 21 for him this year. He is 10. What would you recommend?

It really depends on his strength. The CAT 5 is lightweight and very balanced, so if he is a strong hitter the 29/21 would be fine.

12107

Can this bat be used in Pony Baseball

Yes. This is approved for pony leagues.

11922

my son was swinging a 30-20 gen x very well last year we have tried the new voodoo 29-21 not happy with it, the claim to the cat 5 is it swings lighter how would it compare to these bats weight wise? dont know whether to get a 30-22 or a 29-21? Thanks

The Cat5 would swing lighter than the Voodoo. As to the size to go with, I generally don't recommend going down in length, because how fast boys grow. Depending on your son's age and size, the 30-22 would be a good one, because the Cat5 is more balanced.

If he did well with a 30-20 gen X, then he would probably do well with a 30-22 in cat 5, because of its balanced swing weight.

11156

What does the words Senior referring to?

Senior league means "big barrel". Most of them will be 2 5/8".

11053

does this bat have the USAAA 1.15 stamp

Yes, it does.

10817

I've seen a lot of questions about whether the bats have the USSSA sticker. The -8 I bought a couple months ago from you has the sticker.

This bat will feature the USSSA stamp on the bat.

10073

my 11 year old has been using a 29-19 oz bat will adding 2 oz in weight be too much for him?

If he is a pretty strong kid and is handling the 29-19 pretty easily,he would be ok. But if he is smaller, that 2 ounces can be a lot. But keep in mind the Cat 5 has a nice balance so it swings light.

9812

Do you have the CAT 5 2012 model with BPF 1.15 and Pony league stamps in -8 (31,23) drop?

Marucci CAT 5: MSB2 Senior League is the model you are looking for.

9394

Is the Marucci Cat 5 legal for use for 13-15 yr. old Babe Ruth?

Yes, this bat has an aluminum barrel and has the USSSA 1.15 stamp on the barrel of the bat. This bat will be legal for you to use. I would still make sure you are able to use this bat with your coach or the head of the league.

8892

I am trying to decide between the cat5 and the new easton power brigade drop 8 bats. I am small for my age (90lbs, 5 foot, and 13 years old) and i really need to know which one is better for me. Please reply.

Both bats are good, it will be just up to what you like. They each have very good sweet spots and will be durable bats. It's a toss up.

8307

Any idea on how many inches from the barrel end of the bat the center of mass (balance point) is? Trying to figure out if the swing weight will be closer to 23 oz.

That's a good question. One that we don't have the answer to unfortunately. I would try to contact Marucci. Their phone number is 1-888-627-8224.

7240

How do you get your name ingraved on the bat?

We currently don't have the capability to ingrave names on a bat. You might try calling Marucci at 1-888-627-8224.

5133

I purchased 2 Marucci Cat 5 Bats in 2011. Can Marucci stamp these bats for USSSA for use in 2012?

As far as I know, Marucci cannot add a stamp to a bat that was manufactured without one. If you would like to contact them directly, their phone number is 1-888-627-8224.

4782

will the 2012 marucci cat 5 with the stamp be relesed before 2011 winter?

We do not have an estimated time frame for the 2012 Cat 5. When we get them in stock they will be up on our website.

4781

when is the -8 going to get the stamp ...1.15 bpf stamp for usssa?

We should be getting these bats in stock at the end of September. Once we get them in stock they will be up on our website.

4650

I purchased the CAT SQUARED 5 in April, the plastic end part of the ANIT VIBRATION KNOB keeps coming loose. I sent the bat back last week for Marucci to take a look at it... do you know what the turn around time is? Cause my son needs his bat ASAP for his travel ball.... thanks!

I'm sorry to hear about your son's bat. Since Marucci is handling your return and I don't have any of your information, you can contact Marucci at 1-888-627-8224. They will be able to give you the status of your return. You can also give us a call at 1-866-380-2287, provide us with your RA# provided by Marucci and we can give them a call on your behalf.

4271

When will the bat have the stamp on it?

The latest information we heard is that sometime in September these bats will be released with the USSSA BPF 1.15 stamp.

2354

will the 2012 marucci cat 5 senior league bat have the usssa stamp on it cause i play for a team in lousiana usssa an every tournament we have is sponsor by marucci so i thought they would have stamp on the 2012 cat 5 senior leage

This is a 2011 model and it does not have the BPF 1.15 stamp. The 2012 Cat 5's that will be released later this year will have the USSSA BPF 1.15 stamp.

1898

So, this will not be eligible for usage in 2012 due to a rule change, or is it eligible but, it is missing the sticker?

This bat is eligible, but in most leagues, the bats will have to have the USSSA and 1.15 BPF stamp on them. This bat does not have that on it. The 2012 models will have them.

1868

u think the cat 5 for senior league will have a stamp on it for next year but they just didnt put the stamp on yet??? cause i hope they be able to be used next year

The 2011 Cat 5’s do not have the stamps on them. In most leagues they might not be able to be used next year if the league mandates that the stamps are on the bats. The 2012 Cat 5’s will have the stamps on them.

1838

will marucci cat 5s be able to be used next year for usssa 13u?

As of 5/2/11, none of the big barrel Cat 5 Senior League bats have been approved for USSSA play in 2012. They do not have a USSSA BPF 1.15 stamp.

866

Is it bbcor approved?

No, this bat is not BBCOR certified. BBCOR only applies to Adult baseball bats. Senior League bats like this one are not required to meedt BBCOR certification.
