CAT X

## Marucci CAT X Bat

The Marucci CAT X is a single-piece alloy bat that features a huge barrel and powerful out-of-the-wrapper performance. Designed with precision, the CAT X exemplifies Marucci's commitment to pushing the boundaries of technology and engineering in bat design. Founded in 2009 with a commitment to enhance the game using top-tier equipment, Marucci has since made significant advancements in bat technology thanks to direct collaboration with professional athletes. This relationship with some of the game's top players ensures Marucci's products are crafted with a keen understanding of what athletes truly need at the plate.

**Perfect bat for:** High school and collegiate players who demand elite performance, superior balance, and a more responsive feel from their equipment.


### Key features include:



* **AZR Alloy Construction:** Offers a more responsive microstructure for better feel, more forgiveness, and enhanced performance at the plate.
* **Multi-variable wall design:** Creates an expanded sweet spot and thinner barrel walls that are more forgiving after off-centered contact.
* **Ring-free barrel technology:** Provides maximum performance with no “dead” spots, ensuring every hit feels solid and powerful.
* **AV2 Anti-vibration knob:** Features an upgraded, finely tuned harmonic dampening system for better feel and less vibration.
* **Professionally Inspired Handle**: Features a removable taper and ergonomic knob shape for more top-hand control and comfortable swings.


### Top competitors comparison: The [Rawlings Velo ACP](https://sidelineswap.com/shop/baseball/bats/rawlings/velo-acp/l164357) and the [Easton ADV 360](https://sidelineswap.com/shop/baseball/bats/easton/adv-360/l59709)

Marucci's CAT X sets itself apart with its unique AZR alloy construction and anti-vibration technology. It is ideal for players looking for a blend of traditional feel and modern performance enhancements. While the Rawlings Velo ACP leads the field with its Accelerated Carbon Performance for a lighter swing, and the Easton ADV 360 capitalizes on its Launch Comp™ technology for higher flex and response, the CAT X shines with its superior balance, reduced vibration, and increased sweet spot thanks to its proprietary construction and design features.


### Progression of the Marucci CAT X Baseball Bat:


Here is a list that details the progression of this series, highlighting the main features and advancements with each new model. 


**2019 - [CAT8](https://sidelineswap.com/shop/baseball/bats/marucci/cat9-2/l163499), CAT8 CONNECT, CAT COMPOSITE**



* CAT8, CAT8 Connect, and CAT Composite are launched.
* The barrels of CAT8 and CAT8 Connect are constructed using the new AZ105 alloy for higher performance at the sweet spot.
* Introduction of SDX EXT connection technology for a stiffer connection and improved energy transfer.
* CAT Composite, a two-piece composite bat, is introduced with SDX EXT and ring-free barrel construction. 


**2021 - [CAT9](https://sidelineswap.com/shop/baseball/bats/marucci/cat9-2/l163499) and CAT9 Connect**



* CAT9 and CAT9 Connect are released with the new AZR alloy for a more responsive microstructure.
* CAT9 features a 2nd Generation AV2 Anti-vibration knob and additional weight below the hands for better control.
* CAT9 Connect introduces the Outer-Locking System (OLS) for an even stiffer connection and virtually zero vibrations.

**2023 - [CATX](https://sidelineswap.com/shop/baseball/bats/marucci/cat-x/l175792), CATX Connect, and CATX Composite**



* The CATX, CATX Connect, and CATX Composite represent a significant generational change.
* CATX features AZR Alloy with new barrel profiles and an ergonomic, custom-shaped tapered handle.
* CATX introduces Liquid-Gel anti-vibration technology.
* CATX Connect and CATX Composite maintain the OLS and introduce S-40 composite handle for increased performance and energy transfer.
* Barrel profiles are reshaped for better balance, with a focus on data from the Baseball Performance Lab.


### What people are saying (edited for clarity and brevity)

**PROS**



* Decent pop and has good barrel control. It seems lighter due to the way it;s balanced. If you’re thinking of moving up in size, do it with this bat.
* I got my son the CAT X BBCOR 33" bat. He chose it over his Voodoo One for his high school varsity games. The CAT X seems well-built, and other players using it have had no issues. In contrast, two of his teammates' Voodoo One bats have already broken this season.
* The grip is cushioned and comfortable. The liquid gel handle reduces vibrations and the "sweet spot" on the barrel is forgiving. Highly recommend this bat.

**CONS**



* The BBCOR Cat X is by far the worst Marucci we've ever bought. It has NO Pop and sounds like he's hitting rocks with the bat. The ball barely leaves the infield when he hits it. 
* Broken in by underhand toss of 160 pitches. Handle broke in a week. Wearing gloves saved the my son's hands.
* Unfortunately my son has been using this bat for only a few weeks and there is already something rattling in the handle.


### **Certification**: BBCOR and USSSA


### Expert Notes ([Tony](https://sidelineswap.com/locker/batexperts))

CATX came out in 2023. The first gen is a white ribbon silver bat. For the second run, Marucci came out with a version called the CATX Vanta. It's a blacked-out, limited-edition. Both gens are an alloy one-piece bat, both very strong performers. They took the alloy and strength from the CAT9 and applied the balance and feel from the CAT8 to develop the CATX.

### What people are saying (edited for clarity and brevity)

  

**PROS**

-   Great for kids who need to "feel the barrel" during their swing. The ball jumps off this bat well. It has never collapsed and provides enough feedback to know how you hit it. Vibration is only felt when hitting the handle.
    
-   "My 12-year-old son upgraded to a Marucci Cat 9 -5 bat from a 30" -8 bat and is hitting great with it. Although the bat is heavier, it is well-balanced and solid. Highly recommended for kids upgrading to a -5."
    
-   Bought the Cat 9 BBCOR bat for my 13-year-old son. It's well-balanced and has good pop for a one-piece. Vibration-resistant knob helps with miss hits. My son loves it and is hitting the ball well.
    

**CONS**

-   Good bat for my 10-year-old, but didn't hold up well in New England cold spring. Dead after one AAU season despite hard hits and dingers. Would have given 5 stars if it lasted longer.
    
-   My son used this bat for 1 season and it has multiple dents in it. He is 12 and weighs about 70 pounds. Thought I would get more than 1 season out of the bat.
    
-   Bought a bat for my 6-year-old son a year ago. It's good but lacks the power and balance of CATX Aluminum. Looking for sales to buy CATX.
    

  

### Certification: BBCOR

### Expert Notes ([Tony from BatExperts](https://sidelineswap.com/batexperts))

They took the same design from the CAT8 and strengthened the CAT9 with a stronger alloy to avoid any denting issues. It's a very good, durable bat. The CAT9 will be a bit heavier than the CAT8; it's a better bat for stronger kids. The first generation of the CAT9 came out with a gray, black, and red paint job. The second generation they called the Past Time, which was red, white, and blue. It's the same bat, but a different paint job. The second bat was more popular simply because of how it looked. Everyone likes the American Flag with its Stars and Stripes.

CAT X Composite

## Marucci CAT X Composite Bat

### 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


### Expert Notes ([Tony](https://sidelineswap.com/locker/batexperts))

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.

**PROS**



* This bat is one of the best options available for young players. It is USA-regulated and commonly used in little league. It offers excellent control and feel and has a large sweet spot for hitting home runs.
* I bought a new bat for my son a month ago since he had outgrown his old one. The new bat is longer and heavier, and he's happy with it. His game has improved since he started using it.
* Marucci's bat is lightweight, durable, and has an old-school sound when solid contact is made. My son has been hitting great with it.

**CONS**



* I like Marucci bats, but this is the 3rd time I've bought one that's heavier than listed. Bought a 28" 17 oz 2022 USA Cat for my 8 y/o son, but it weighed 19.3 oz. Will keep trying with Marucci, but they all tend to be heavier than listed.
* Purchased a 29” 18oz. bat, but it weighed 20.3 oz.
* I bought this product for my son and when I asked him to rate it, he gave it four stars. He explained that he didn't give it five stars because he feels too much vibration upon hits and it doesn't have the best pop.


### **Certification**: USA


### Expert Notes ([Tony from BatExperts](https://sidelineswap.com/batexperts))

The Marucci CAT is designed for Little League. It has that USA stamp, which means it has a lightweight feel and good control. The CAT has an affordable price point, so it won't break the bank. A lot of parents get this bat specifically because it's a quality bat with a good bang for the buck.

### What people are saying (edited for clarity and brevity)

**PROS**



* My son enjoyed using. It did not cause any pain and had decent hitting power.
* This bat is a great buy with a lot of pop and no stinging. It has a fast swing and is well-balanced, improving confidence. Kids will love it for little league. 
* Well balanced, no shock, decent pop. My 9 year old likes the added two inches compared to his previous bat. Likes that it doesn’t rattle his hands. Very pleased for the price 

**CONS**



* I purchased this bat for my 9-year-old son to use in little league. Sadly, it did not last long and got cracked in the same weak spot as many other bats.
* The bat snapped in 1/2 while my 9 year old son was hitting.
* My 8 year old son hit very well with it until is snapped in half.

### Expert Notes ([Tony from BatExperts](https://sidelineswap.com/batexperts))

The CAT9 Connect is going to be in the same market as the Select Power, The Goods, and the Voodoo. It's a two-piece hybrid alloy barrel with a composite handle. It's a top-three bat for me. Very good performer and very popular. Just a great overall product. 


Pop: ⭐⭐⭐
