New for the 2019 season! Take your game to the next level with the new and improved Marucci bat lineup. The CAT 8 USSSA Baseball Bat features a maximized barrel length provides a wider sweet spot thanks to its longer surface area. One of the main differences from the CAT 7 is the new and improved AZ105 Alloy, the strongest aluminum on the Marucci bat line, allows for thinner barrel walls, a higher response rate and better durability. This Marucci bat's one-piece alloy design blends year-round durability with a traditional feel, and its ring-free barrel construction eliminates dead spots while improving flex. Its precision-balanced barrel provides a lower M.O.I. and balanced feels that makes it easy for any style of hitter to enjoy their personal best results. New for the 2019 lineup is the 2nd Generation AV2 Anti-Vibration Knob that features an upgraded, harmonic dampening system for better feel and less negative vibrational feedback. Marucci Sports: Honor the Game.
This Marucci CAT 8 USSSA Big Barrel Bat features a -5 length to weight ratio, a 2 3/4 inch barrel, and the USSSA 1.15 BPF certification. The sting-free comfort knob is ergonomically-molded nylon engineered for best comfort and control, complemented by a micro-perforated soft-touch grip whose extra tack makes for a no-slip hold. Every element of the CAT 8 craftsmanship comes together to earn a sterling reputation: these Marucci bats provide simply the best look and feel with the most "pop" off the bat and the least vibrational feedback, making an ideal fit for any age and strength of hitter.

add_circle_outlinePros: 13 y/o crushes with this bat. He doesnt complain about any sting at all. It seems like the ball jumps off the bat even more than the cat7.
remove_circle_outlineCons: I wish the bat came standard with a lizard skin grip. After a few weeks of use the grip seems to lose some of its tackiness (durability). But it is easy enough to change grip.
add_circle_outlinePros: My smallish 12 year old is using the -5 to prepare for middle school in the Spring when he has to go to BBCOR. The bat is so well balanced that it feels and swings much lighter than it is. The pop is very good as well and you can tell by the sound if he has hit it on the sweet spot. No idea on durability yet as he has only hit about 100 pitches and taken 100 swings off the tee but it seems to be solid so far.
add_circle_outlinePros: My son is a 5’5 132 pound shortstop/pitcher. He is on a competitive travel team. He has been batting in the 9 position until he wrapped his hands on this bat. He has quickly moved up to “cleanup hitter”. It is amazing how hard the ball is coming off this bat, but most of the power is probably coming from his dedication in the weight room this winter. He max benches 120 pounds by the way. I feel for the pitchers who have to face kids with this bat in there hands.
remove_circle_outlineCons: Every kid on the team wants to use it. I might buy another for the team so people won’t wear down the pop on my sons bat.
My undersized 12 year old will be transitioning from -7 weight/length ratio to -5 standard for travel league play. His previous bat was 28 inches and my first question is why can't I find a -5 bat at 29 inches as the smallest at that ratio is 30 inches? He will be making a huge jump in bat size given his size so what 30/25 bat model would you recommend as I would think I would want to avoid end loaded models and get him into a more balanced weight distribution?
Unfortunately the bat manufacturers, based on their market research, start their -5 models at 30 inches. Your thinking would be correct in that a balanced bat would be more beneficial for your player since he is having to jump up in weight. The 2019 Marucci CAT 8 -5 USSSA Baseball Bat: MSBC85 would certainly make a great choice as this bat features a balanced swing weight design.
What is the difference between this CAT 8 and the CAT 8 composite? Thinking about how the bat performs for the player, primarily, as well as if there are temperature restrictions unique to one bat and not both.
The 2019 Marucci CAT 8 -5 USSSA Baseball Bat: MSBC85 is a one-piece all alloy bat with a balanced swing weight while the 2019 Marucci CAT 8 Composite -5 USSSA Baseball Bat: MSBCCP5 is a two-piece all composite bat with a balanced swing weight; both have 2 3/4" barrel diameters. The composite model is best suited for the warmer weather but does not have any restrictions with regards to temperature. As well, since the composite model is made from a two-piece design one would get more flex and vibration control from an off-centered hit.
What are the differences between the -5 CAT 7 and CAT 8 bats?
The 2019 Marucci CAT 8 -5 USSSA Baseball Bat: MSBC85 features a new alloy barrel (AZ105) that gives this bat a lighter feel with thinner barrel walls for a higher trampoline effect when compared to the CAT 7. As well, the AV2 knob has been improved to further reduce vibration from an off-centered hit.
Any issues with possibly damaging the bat if it is used with heavy practice baseballs like the Total Control Ball?
There is a good chance one could damage the 2019 Marucci CAT 8 -5 USSSA Baseball Bat: MSBC85 is using a heavier ball to hit with like the Total Control Ball. Would recommend using ones non game bat for this type of hitting.
What is the difference between the CAT 7 and the CAT 8?
The 2019 Marucci CAT 8 -5 USSSA Baseball Bat: MSBC85 will have the upgraded AZ105 alloy, the strongest aluminum on the Marucci bat line, allows for thinner barrel walls, a higher response rate and better durability.
I've heard that the Cat 6 actually has more pop than the Cat 7 or newer Cat 8. Does anyone have any first hand experience with this?
No, I do not subscribe to that notion. The Cat 7 and 2019 Marucci CAT 8 -5 USSSA Baseball Bat: MSBC85 have been two of our highest reviewed models to date. I do not believe that there has been any performance drop-off. If anything, the performance has increased.
I'm 14 years old and have to use -5 bats this year before BBCOR. I'm 5’7", around 115 lbs, and am looking to hit for contact but also with loads of power. My narrowed down choices are the Cat 8, Beast Pro, and Ghost X composite (white and grey). What should I choose?
All bats mentioned are great ones to consider. As for the size to get the 2019 Marucci CAT 8 -5 USSSA Baseball Bat: MSBC85 in, we would recommend a 31 inch bat per your height and weight.
Will the Cat 8 be certified for use by USA Bat?
The 2019 Marucci CAT 8 -5 USSSA Baseball Bat: MSBC85 is USSSA certified for USSSA travel ball play, and will not be legal for play in any league requiring the USA Baseball stamp.
Is this bat okay to use this in a batting cage environment hitting the yellow dimpled machine balls or is there a possibility of damaging it?
We do not recommend using any of your new bats in a cage with the yellow dimple balls, and the 2019 Marucci CAT 8 -5 USSSA Baseball Bat: MSBC85 is no exception. Those particular balls are heavier and more dense which can cause noticeable damage to any model.
Are the handles tapered with a thicker handle near the knob on all CAT 8's or is that just the grip?
Based on the AV2 knob that is used on the 2019 Marucci CAT 8 -5 USSSA Baseball Bat: MSBC85 one will notice that the handle is thicker or slightly flared at the base of the handle/knob. This design would be the same on all CAT 8 models.
Will this bat be allowed for Babe Ruth? 13-15 years old?
Generally speaking, the 2019 Marucci CAT 8 -5 USSSA Baseball Bat: MSBC85 will NOT be approved for Babe Ruth play as it is not USA certified. However, you will want to check with either a coach or league official to verify your league's exact rules.
Is the 2019 Marucci Cat 8 (MSBC85) approved for babe Ruth 14 yr old and travel team play?
This bat will not be approved for both Babe Ruth and travel league play. Babe Ruth requires either a USA stamped bat or a BBCOR stamped bat, and this 2019 Marucci Cat 8 -5 USSSA (MSBC85) does not have either of those certifications. It only has the USSSA stamp for travel ball play.
