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.
* **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.

Mako

### Expert Notes
Endurance is the name of the game when it comes to Easton’s Mako bat series. Despite being discontinued in 2017, Easton Mako bats continue to sell very well in the modern market. This two-piece composite bat offers an additional jolt of pop at the plate, and its anti-vibration technology makes getting jammed a little less painful—physically, at least. The 2016 Easton Mako, in particular, has ascended into baseball bat folklore because of its neon green colorway and insane ability to demolish baseballs (although some hitters prefer the orange 2015 model, too). Considering the fantastic prices you can find Easton Mako’s listed at, it remains a top metal bat value pick.

## Marucci CAT Baseball Bat



The Marucci CAT is a bat designed for superior performance straight out of the wrapper. Engineered with a precision-balanced and ring-free barrel construction, the CAT series allows for maximum swing speed, control, and an expanded sweet spot for a more forgiving hit. From its ultra-responsive alloy to its ergonomically designed handle, every aspect of the Marucci CAT has been crafted to elevate a player's game and provide comfortable contact at the plate.

 
**Perfect bat for:** Young players looking for modern performance and extra comfort on contact. 



### Key features include: 




* **AZ105** Super Strength Aluminum Alloy:** Offers a thinner barrel wall for a higher response rate and increased durability.
* **Multi-Variable Wall Design:** Expands the sweet spot and reduces dead spots for more consistent performance across the barrel. 

**Anti-Vibration Knob:** Provides a better feel and reduces negative vibrational feedback to the hands, ensuring comfortable swings.
* **Precision-Balanced Barrel:** Results in a lower M.O.I. and balanced feel for precision and control.
* **Ring-Free Barrel Construction:** Allows for more barrel flex and increases performance without "dead" spots.
* **Micro-Perforated Soft-Touch Grip:** Enhances comfort and tack, promoting better control and reducing hand fatigue during swings.
* **One-Piece Alloy Construction:** Delivers a clean, consistent, traditional feel with built-in durability and performance.



### Top competitors comparison: [DeMarini CF](https://sidelineswap.com/shop/baseball/bats/demarini/cf-20/l59398) and [Louisville Slugger Meta](https://sidelineswap.com/shop/baseball/bats/louisville-slugger/meta/l59403)

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.

###  What people are saying (edited for clarity and brevity)

**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.

Threat

### Expert Notes
Rawlings wanted to create a bat that’s meant specifically for smaller framed
players—and that’s just what they did with the Threat. The newest 2022 Threat comes
in an awesome Stars and Stripes themed colorway that we all
love, and delivers on its promise of enabling smaller hitters to swing with extra speed
through the strike zone. The 2022 Threat has evolved from when the series started in
2018 by adding even more width to an already expansive barrel—although I’ve heard
young hitters still love the 2019 Threat, as well (if only because of its neon green
colorway). If you seek a one piece composite bat that isn’t going to break the bank and
will benefit those who haven’t yet grown into their natural power, the Rawlings Threat
series stands alone.

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.
