## 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.

### 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 bat has a fantastic feel, sound, and performance on miss-hits. It boasts one of the largest sweet spots in BBCOR. Although it lacks feedback, it is very easy to swing.
* Great feel and pop. Although I usually change grips, the stock grip on this bat is solid. The durability is very impressive as well, as the bat has already outlasted most others.
* No failures on Meta bats except cosmetic chips. They perform better than new. High school varsity team used 32-3 for 2 years without issues. Change grip tape yearly and keep hitting!

**CONS**



* The finish will chip if hit against spikes.
* It's expensive.... and not crazy about the color.
* This bat has no pop.


### **Certification**: BBCOR, USSSA


### Expert Notes (Parker)

The Louisville Slugger Meta is still a slightly newer model. The meta is similar to the DeMarini CF which offers a lightweight composite handle with a huge barrel made for every sort of hitter. A popular series that offers great jump-off-the-barrel when you hit the sweet spot and keeps the sting off your hands when the ball is missed on the cap or handle.

### What people are saying (edited for clarity and brevity)

**PROS**

-   My son hit three home runs with the Goods bat at a college prospect camp this weekend. He says the current version feels amazing and is the best one yet.
    
-   I upgraded to this bat from my broken 2022 Goods. It has phenomenal pop and is the best in the Goods line.
    
-   This bat bangs!!! I bought this bat three weeks ago and this barrel is huge!
    

**CONS**

-   My son loved this bat from day one. After three weeks of use the plastic piece where the shaft meets the barrel cracked. Definitely expect something better than this for $450. Haven't started the warranty process yet so we'll see how that goes.
    
-   The bat handle now telescopes into the barrel after the junction cracked. We had expected better quality for the price and it's hard to accept a replacement that arrives 2-3 weeks later at best.
    
-   Bat bought 2 months ago broke when I dropped it. It's a good bat but not very durable. Connector piece broke and it telescoped.
    

  

### Certification: USSSA, USA, BBCOR

### Expert Notes ([Tony from BatExperts](https://sidelineswap.com/batexperts))

The Goods is a top performer and the 2024 model is the most expensive hybrid bat on the market. It's an end loaded bat for that power hitter in your lineup. The alloy is strong, and it has a good whip to it. Overall, The Goods is in the top five in the hybrids for both BBCOR and youth. The youth was less popular because it was a heavier-feeling.

The series also serves as a testament to Marucci’s commitment to applying data and insights from professional hitters.

**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:

### 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.

### Evolution of the CF Zen Series 

Here is a list that details the progression of this series, highlighting the main features and advancements with each new model.

### What people are saying (edited for clarity and brevity)

**PROS**



* Good bat, with less pop than 1-piece aluminum. Ideal for singles with a lighter swing weight. Composite material, so have 2 bats for high competition.
* My son is 11 years old. I was worried he would struggle to swing a 30/20 bat this year, considering he used a 29/19 bat last year. However, this bat is amazing! It is hot right out of the wrapper. I wouldn't even think about using another bat this year; this one is perfect.
* This is the best overall USA bat on the market. It has decent pop and great balance, making it a high-quality option.

**CONS**



* "The bat developed cracks in the sweet spot from regular use during batting practice. After six months, the cracks grew larger until there were two major ones, resembling a cave-in."
* Bat has pop but I've had a couple of friends crack this same bat after 4 games.
* Bought it for my son, 2nd time he used it, it cracked. He only hit league baseballs with it in warm weather.


### **Certification**: BBCOR, USSSA, USA


### Expert Notes ([Tony from BatExperts](https://sidelineswap.com/batexperts))

The CF Zen has been discontinued. The early models from 2017 - 2021 were called CF Zens. After that, DeMarini changed the name to CF. The first models of the CF Zen were very high-performance. But they also tended to break, so DeMarini made them stronger, made them stiffer, made them more durable. And when they did that, the bats didn't hit as well. The early models were better performers than the later models.

## 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.


### Key features include:



* **Two-Piece Hybrid Construction:** Combines a carbon composite handle with an AZR alloy barrel for a reduced vibration on contact and a more comfortable, controlled swing.
* **Outer-Locking System (OLS):** Marucci's exclusive connection technology enhances stiffness and energy transfer by creating a tighter connection between the barrel and handle.
* **AZR Alloy Barrel:** Engineered for increased responsiveness and durability, offering a better feel and more forgiveness with every swing.
* **Power-Loaded Barrel:** Tailored for power hitters, providing an end-loaded swing weight that enhances force without compromising bat speed.
* **Micro-Perforated Soft-Touch Grip:** Ensures superior tack and cushion for improved handling and reduced hand fatigue during long batting sessions.
* **Professionally Inspired Handle:** Features a removable taper and an ergonomic knob shape for improved control and comfort.

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**



* 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.


### **Certification**: BBCOR


### 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: ⭐⭐⭐

Durability: ⭐⭐⭐⭐
