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.

The rivals include the Easton ADV 360 and the Louisville Slugger Solo.

While the Easton ADV 360 is prized for its 360-degree barrel tuning for precision across the entire barrel and the Louisville Slugger Solo is known for its ultra-balanced swing weight for ultimate swing speed, the Cat 9's multi-variable wall design and precision balancing mean it excels in providing young hitters with a powerful, yet manageable tool to enhance their game.

### Progression of the Marucci CAT 9 Baseball Bat:

### 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.

### What people are saying (edited for clarity and brevity)

**PROS**



* This is an excellent one-piece bat with a balanced feel.
* My son is using his first BBCOR bat. Although he was previously using a -5 USSSA bat, he hasn't noticed any difference in the weight. He has already had success with it on the big ball field this fall. This one-piece alloy bat is great, especially in the Northeast where temperatures are cooler.
* I am very satisfied with this bat. My son has recently started playing on a 60/90 field. This bat has excellent balance and a large sweet spot. It has great pop right out of the wrapper, so there is no need to break it in. Additionally, it looks great too.

**CONS**



* Bat is too light, causing players to swing early. It doesn't have as much power as a BBCOR composite bat. 
* Not suitable for heavy hitters; ideal for children who require a lighter bat for swinging. Grip must be perfect, or it will sting hands.
* The sound changed, and when the handle was tapped on the ground, it produced a vibrating sound.


### **Certification**: BBCOR, USA


### Expert Notes ([Tony](https://sidelineswap.com/locker/batexperts)) 

DeMarini's Voodoo One swings light and offers a ton of pop thanks to its stiff one-piece alloy construction. While the small barrel might not be for everyone, contact hitters and power swingers both appreciate its speed and distance potential. If you're a player seeking a light bat with serious pop, the Voodoo One deserves a swing. 

Pop: ⭐⭐⭐⭐⭐

Durability: ⭐⭐⭐

CAT8

## Marucci CAT 8 Baseball Bats 

 
The Marucci CAT 8 series is part of a lineup of bats consistently praised for outstanding performance and durability. The CAT 8 is a two-piece composite bat designed for a blend of power, speed, and control at the plate, with an expanded sweet spot to help hitters achieve their full potential. The series also serves as a testament to Marucci’s commitment to applying data and insights from professional hitters. Founded in a backyard shed in 2002, Marucci Sports has grown into one of the most reputable names in baseball equipment over the past 20 years. 

 
**Perfect bat for:** Youth to college-level players who are in search of a bat that offers a blend of power, speed, and comfort.


### 
Key features include:




* **AZ105 Super Strength Aluminum Alloy:** Offers thinner barrel walls for a higher response rate and unmatched durability.
* **Multi-variable Wall Design:** Expands the sweet spot and reduces weight, enhancing forgiveness and power.

### Top competitors comparison: [The Louisville Slugger Omaha](https://sidelineswap.com/shop/baseball/bats/louisville-slugger/omaha-2/l8755) and the [DeMarini Voodoo](https://sidelineswap.com/shop/baseball/bats/demarini/voodoo/l7333) 

Marucci CAT 8 particularly excels in its use of AZ105 alloy for durability and a thinner barrel for a higher response rate. While the Omaha and Voodoo are known for their balanced swing and innovative technology, the CAT 8 sets itself apart with its anti-vibration technology and multi-variable wall design, the cat 8 uses 8 different thicknesses of barrel wall, offering players a mix of comfort, power, and precision that is hard to beat.


### Progression of the Marucci CAT baseball bat

Here is a list that details the progression of this series, highlighting the main features and advancements with each new model.

 


**2014 **-** [CAT6](https://sidelineswap.com/shop/baseball/bats/marucci/cat-6/l7498)**



* Building on the ring-free barrel design, Marucci releases the CAT6 with an extended, optimized barrel made from the AZ3000 alloy.
* Patented anti-vibration knob takes on additional weight for a more balanced feel and faster swing speeds.

**2017 **-** [CAT7](https://sidelineswap.com/shop/baseball/bats/marucci/cat-7/l7247) & CAT7 CONNECT**



* CAT7 and CAT7 Connect are introduced, featuring the upgraded AZ4X alloy for improved performance.
* CAT7 has a one-piece alloy construction, while CAT7 Connect offers a two-piece hybrid design with a carbon composite handle.
* Both models feature an increased sweet spot and an upgraded anti-vibration knob (AV2). 


**2019 **-** [CAT8](https://sidelineswap.com/shop/baseball/bats/marucci/cat8-2/l7709), 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.


### What people are saying (edited for clarity and brevity)

**PROS**



* I am pleased to say that my son has experienced an increased exit speed and longer distances. He has noticed that the bat has an expanded sweet spot, resulting in more comfortable hits with less sting.
* My son had a few mishits but the ball still came off decently, and he mentioned that there was no vibration. I would recommend this bat, especially for younger kids who are improving their skills but still want success.
* A go-to choice when under pressure. It has a large sweet spot, providing a ton of power. The bat is also easy to swing and consistently achieves a higher exit velocity off the tee compared to a Cat9 alloy and 23' meta.

**CONS**



* I purchased the -8 version, which has a small sweet spot. The knob is great, but the grip is not as effective. 
* If you are still 11, I suggest you get the drop ten because it has a bigger sweet spot and more pop due to its smaller aluminum content. Overall, it's a nice medium-swinging -8! 
* I was unaware that this bat was the Junior version and only recommended for Coach Pitch.


### **Certification**: USA, USSSA, BBCOR 


### Expert Notes ([Tony](https://sidelineswap.com/locker/batexperts)) 

The CAT8 is an older model from 2019 and a good BBCOR and USSSA bat. Very good performing bat with a sound that players love. Lightweight and easy to swing. It's probably one of the best sellers, and since the CAT8 is still available, it's perhaps one of the better bang for the buck. Prices dropped for this older model. So, it is a good match for an entry-level player on a tight budget.

Compared to leading competitors like the DeMarini CF and Louisville Slugger Meta, the Marucci CAT series distinguishes itself with its one-piece alloy construction and AZ105 Super Strength Aluminum Alloy, which offers hitters a traditional, yet highly responsive feel. While the DeMarini CF is known for its two-piece composite design that emphasizes flexibility and feel, and the Louisville Slugger Meta prides itself on its three-piece composite build for balance and speed, the Marucci CAT excels in delivering direct feedback, explosive power, and a classic feel, making it a solid choice for players who appreciate the simplicity and effectiveness of alloy bats.

* 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.

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.
