## 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.
* **Precision-balanced Barrel:** Designed for optimal swing speed and control, improving hitters' performance across all levels.
* **AV2 Anti-Vibration Knob:** Delivers a better feel and minimizes sting on mishits, ensuring comfort during every at-bat.
* **Ring-free Barrel Technology: **Increases flexibility and promotes maximum performance with no "dead" spots on the barrel.
* **Micro-Perforated Soft-Touch Grip:** Provides superior grip and comfort during every swing. 



### 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.

Prime 919

### About the Louisville Slugger Prime 919

Louisville’s Slugger’s Prime 919 bat is BBCOR certified and one of the best performing two-piece composite bats on the market. With a large barrel and lighter swing weight, the Prime 919 is a balanced bat with a mix of power and speed. Brand new in 2019, the patented VCX Technology improves the durability and weight distribution of the bat to control vibrations and enhances the soft feel on contact. The RTX end cap contributes to a larger barrel and provides a larger sweet spot for both power and contact hitters alike. The new LS PRO Comfort Grip is an upgrade from the traditional Lizard Skin Grip in prior years and improves the cushion and tackiness of the grip.

Omaha 519

Avenge

### Product Descriptions

Axe Avenge BBCOR certified bats deliver ACR hitting zone technology for maximum barrel performance, power, and speed. With a 270 degree engineered hitting zone, the Avenge is designed for maximum performance, strength, and durability. The perfect combination of power and speed, the Avenge utilizes carbon hyperwhip end cap technology to reduce weight distribution at the end of the baseball bat and a vibration canceling system (VCS) to reduce hand vibrations for a smoother shock absorbing swing. Added in 2019, the 3-piece composite bat construction and the charged carbon barrel provides improved performance along the length of the barrel in addition to a lighter swinging bat that feels smoother on mishits. The flex handle with shock absorbing endogrid technology built into the handle maximizes whip through the hitting zone, enhances overall comfort, and reduces bottom hand vibrations.

### Export Notes

Early in the lineup hitters, as well as the occasional power guy, will like this bat’s performance. If you thought the Axe Avenge via 2018 swung a bit too heavy for you then it would be time to reconsider the 2019 version. The latest model features a lighter swing weight. All in all, the 2019 Avenge is a lighter swinging bat with a larger usable barrel size and a smoother feel on mishits. These differences are in large part due to changes in the composite make up (to a "charged carbon") that allows for longer performance along the length of the barrel.
