## Marucci CAT 9 Bat


  

The Marucci CAT 9 baseball bat is part of Marucci's highly respected CAT series, known for its balance, performance, and durability. Introduced as an upgrade from the previous models, the CAT 9 incorporates new technologies and materials to provide a superior hitting experience.

  

Since its inception in 2009, Marucci has risen to prominence in the baseball industry by prioritizing direct input from professional players. This player-driven design philosophy has guided the development of some of the market's most trusted and high-performing baseball equipment. Marucci's dedication to quality and performance, coupled with its commitment to a detailed, handcrafted process, has established the brand as a favorite among players at all levels of the game.  
  

Perfect bat for: Youth players who are looking to elevate their game with superior balance, power, and performance.

  

### Key features include:

-   AZR Alloy Construction: Offers a more responsive microstructure for better feel, increased forgiveness, and enhanced performance at elevated swing speeds.
    
-   Precision-Balanced Barrel: Engineered for optimal balance, providing players with control and consistency in their swings.
    
-   Multi-Variable Wall Design: Creates an expanded sweet spot and thinner barrel walls, which help in forgiving off-center hits.
    
-   Ring-Free Barrel Technology: Eliminates dead spots in the barrel, ensuring maximum performance and solid contact throughout the bat.
    
-   Anti-Vibration Knob: Features an AV2 knob that reduces vibration, providing a better feel and minimizing hand sting on mis-hits.
    
-   Micro-Perforated Soft-Touch Grip: Ensures superior comfort and an enhanced feel, allowing for better control and reduced hand fatigue.

### Top competitors comparison: [Easton ADV 360](https://sidelineswap.com/shop/baseball/bats/easton/adv-360/l59709) and the [Louisville Slugger Solo](https://sidelineswap.com/shop/baseball/bats/louisville-slugger/solo/l7816)  
  
The rivals include the Easton ADV 360 and the Louisville Slugger Solo. The Marucci Cat 9 stands out due to its innovative AZR alloy construction, offering a unique combination of feel, performance, and durability that is tailored specifically for the developing player. 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:

  

Here is a list that details the progression of this series, highlighting the main features and advancements with each new model.

  

**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.  
      
    

**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.
    

  

### 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.

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.

CAT9 Connect

## Marucci CAT9 Connect Baseball Bat

The Marucci CAT 9 Connect is an evolution within the Marucci CAT series, specifically designed to cater to hitters who prefer a slightly end-loaded feel and the additional power that comes with a two-piece bat construction. This model integrates Marucci’s latest technology to enhance performance, reduce vibration, and provide a comfortable hitting experience. 

By focusing intently on the needs and feedback of players, Marucci has cultivated a reputation for creating bats that deliver unmatched performance and durability. The Cat 9 Connect combines state-of-the-art technology with a deep understanding of what players truly need to succeed on the field.

**Perfect bat for:** Competitive high school and college players who demand a bat that offers a more end-loaded feel for maximum power—without sacrificing swing speed.

The Marucci Cat 9 Connect sets itself apart with its Outer-Locking System (OLS), providing an unmatched blend of stiffness and energy transfer. While the DeMarini Voodoo is known for its two-piece hybrid design that emphasizes a balanced swing for hitters who want both power and speed, and the Louisville Slugger Select PWR offers a three-piece design for enhanced swing control and reduced vibration, the Cat 9 Connect specializes in delivering a potent combination of speed, power, and precision, making it a formidable choice for players aiming for home runs.

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

* 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.

* My 8 year old son hit very well with it until is snapped in half.


### **Certification**: BBCOR

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.

Velo

### Expert Notes
The longest lasting metal bat series on the market is still at its peak. Rawlings legendary Velo series returned in 2022, with a Velo ACP release that I’ve heard hitters say offers unparalleled balance at the plate. Over time, the Rawlings Velo series has evolved by incorporating the ACP (Accelerated Carbon Performance) line that adds extra carbon in the barrel, which we’ve heard does a lot to increase pop. While Velo’s aren’t the best looking bats you’re going to find, they make up for the plainness with top-notch performance. Rawlings’ resilient Velo series should continue to be a favorite for hard-nosed hitters who prefer production over flash.
