Bat Benefits
Crafted with Marucci's AZ105 aluminum, this model offers superior feel and durability. It's the strongest aluminum alloy in Marucci's lineup, allowing for thinner walls and improved response rate on contact. In addition to the high-end AZ105 alloy, this bat features the Multi-Variable Wall Design for an expanded sweet spot and forgiving response when contact is off center. It's a ring-free barrel designed to create more overall flex and totally eliminate dead spots. The high-end materials, pro-style design and precision balance create a low moment of inertia for superb control.

Contact comfort is central to this bat's design thanks to the improved AV2 anti-vibration knob. Its advanced harmonic dampening system drastically reduces negative vibrational feedback into the hands allowing developing hitters to swing away with confidence. The handle also features a pro-inspired ergonomic shape with a removable taper for a custom fit and better top hand control.

Marucci covers this bat with a limited one-year warranty. This coverage includes any defects in materials and workmanship a

Cat 8 Limited Edition Ron O. Coach

Pros: Great bat. Switched back to an aluminum bat because my 11yr is breaking composite bats. We bought this one just to have a different paint scheme than all the others. I was a little disappointed when we received the bat it had a price tag on it for 229.99 and we paid 289.99. I understand paying a little extra for the limited edition paint scheme but you would think that they would at least change the price tag.

Cons: None

The junior big barrel option of the Cat 8 is not constructed to face pitching above 40mph; it is only recommended for coach/machine pitch.

Are they coming out with a Cat 9 for 2020? My son was crushing the ball with the white Cat 8, so far we haven’t seen anything as of yet.
Scott Nyetrae
At the time of this posting, we are expecting a new release from Marucci Spring 2020.
Why did the bat go up in price?
This model is a limited edition color design and a JustBats exlusive Black/Gold design that is not available elsewhere.
Is there any difference between the 2019 model and the 2020, other than color?
The Marucci CAT 8 -10 USSSA Baseball Bat: MSBC810BG and the white barrel Cat 8 are the same bat except for the color design. Both bats use the same AZ105 Alloy, so you won't be seeing any difference in terms of performance.
Ben C
Is this limited addition Cat 8 the senior league model or the junior big barrel? If it's the junior big barrel, do they sell it in the senior league size?
The Marucci CAT 8 -10 USSSA Baseball Bat: MSBC810BG is the senior league USSSA model intended for kid pitch. It is not the junior big barrel model that is intended for coach pitch or machine pitch.
Do you still have the Marucci CAT 8 -10 USSSA Baseball Bat: MSBC810BG black and gold addition in stock?
Tom Escher
Yes, in the 29", 30", and 31" models. We do run a live inventory, so if we have it in stock it will be listed on our site.
Why is there a price difference between the 29 and 30 vs the bigger 31 inch bat?
Corey Cruikshank
The Marucci CAT 8 -10 USSSA Baseball Bat: MSBC810BG has a price difference in those lengths due to the supply and demand for the shorter lengths (29 and 30 inch).
When will you get some more 28/18 size? Thanks
Unfortunately we will not. This was a Limited Edition color from Marucci and available through us. There is always a chance Marucci releases this color again in the future, but we are not expecting them to do so.
I’m interested in the CAT 8 LE in 27/17 -10, not the junior big barrel. Didn’t see this size here online. Would you happen to have this size bat in stock?
Julio Ortiz
Unfortunately, we have sold out of the 27 inch 17 ounce model of the Marucci CAT 8 -10 USSSA Baseball Bat: MSBC810BG and will not be getting more in stock.
