Marucci CAT X Composite Baseball Bat

players who see a lot of games, high pitch speed, and are willing to spend money on top-of-the-line gear.

Perfect bat for: 

The CAT X Composite is very, very easy to swing. Not quite as popular as the CF in terms of performance. There are newer Marucci  bats out there that are stronger, hotter-performing bats. But it's still a top top-tier bat. It's right up there with the CAT9 composite, but it doesn't get the notoriety because you've got some newer bats on the market with cooler paint jobs.

Tony from BatExperts

The Marucci CAT X Composite Bat is available in both BBCOR and USSSA versions. It swings like a dream thanks to its stiff S-40 composite handle, which provides a balanced swing weight for developing hitters. The CAT X Composite also packs a punch. Its finely tuned composite barrel features a massive sweet spot, creating a trampoline effect for well-struck balls. The outer-locking system also eliminates vibration on contact for a comfortable feel, allowing young players to focus on making consistent, powerful swings.

The 2023 Marucci CAT X Composite is an updated version of the 2021 Marucci CAT 9 composite. Here are the key updates: 

Progression of the Marucci CAT X Composite Baseball Bat

The CAT X Composite boasts a stiff S-40 composite handle for a balanced swing weight, ideal for developing hitters. The Ghost X offers a slightly heavier swing weight due to its two-piece composite construction, but might have an even larger sweet spot. The CF Zen utilizes a Continuous Fiber Composite barrel, focusing on a smooth, comfortable swing with a well-rounded sweet spot size. Ultimately, the choice depends on your preference: balanced swing for developing hitters (CAT X Composite), potentially largest sweet spot with a bit more weight (Ghost X), or smoothest swing with a comfortable feel (CF Zen).

The Marucci CAT X Composite is another innovative model within the Marucci CAT series, expanding the brand's offerings to players who prefer composite bats over alloy. Composite bats, known for their lighter weight and larger sweet spot, provide a different feel and performance compared to their alloy counterparts. Marucci's offerings, like the CAT X Composite bat, stand as a testament to the brand's unwavering pursuit of excellence in every swing.

### What people are saying (edited for clarity and brevity)

**PROS**



* Bought for son transitioning to BBCOR. Light and balanced. Good pop and sound. Great balanced BBCOR bat!
* Like cheating, it’s awesome! Whole barrel is super hot. 33” sweet spot
* Bat has huge sweet spot. Lots of pop!

**CONS**



* My son's bat grip is separating already. The bat lacks the usual sound of CatX or Cat8 bats. We paid extra for the grip, but it's coming apart fast. 
* The price doesn't deserve more than 4 stars, but we appreciate the fast shipping and the name engraving.
* Bought this bat for my 14 year old, felt good during batting practice, but the second he hit the ball in game it broke in half! 500 dollars down the drain.


### **Certification**: USSSA, BBCOR
