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

* 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**

**2021 - [CAT9](https://sidelineswap.com/shop/baseball/bats/marucci/cat9-2/l163499) and [CAT9 Connect](https://sidelineswap.com/shop/baseball/bats/marucci/cat9-connect-3/l164210)**



* 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](https://sidelineswap.com/shop/baseball/bats/marucci/cat-x-connect/l175804), and [CATX Composite](https://sidelineswap.com/shop/baseball/bats/marucci/cat-x-composite/l175805)**

### What people are saying (edited for clarity and brevity)

**PROS**



* It's an end-loaded bat, but it's very easy to swing. You have full control when going through the strike zone, no matter where the ball is over the plate.
* This bat allows you to maximize your swing speed for high ball exit velocities. The sweet spot is huge and covers almost the entire barrel of the bat, making the ball jump off the bat."
* It’s been used for about a month for cage work and early season practice. The ability to consistently barrel or square up on a pitch is better than any bat on the market. The connect version does minimize the vibration.

**CONS**



* The grip is slippery. Even with batting gloves on it’s hard to hold on to it. Easy fix with a lizard skin grip.
* Bat knob fell off after 1st time using, no pop!
* Used for one game and the knob sticker has come off already. 


### Certification: BBCOR, USSA


### Expert Notes ([Tony](https://sidelineswap.com/locker/batexperts))

The CATX Connect is a hybrid bat. It's a strong performer. It's top five in the hybrid market. Very easy to swing, very well balanced. There's a good nature to it; it doesn't dent. It's very durable. But it is an end-loaded bat and a two-piece hybrid, so it's more designed for the power hitter and for stronger players.

### What people are saying (edited for clarity and brevity) 

**PROS**



* A kid in a slump hit his first-ever home run with this bat. It arrived just in time for a playoff game and worked great for my average-sized 11-year-old son - not too heavy.
* After breaking in this bat properly, it really performs well! My son uses it for our USSSA 8U Travel team and you can easily tell when it's hit on the sweet spot. The bat is also forgiving on mis-hits, often resulting in faster grounders than usual (for this age group) and very high pop.
* This bat has more pop than most USA bats, similar to BBCOR/USSA. We broke it in with tee hits, and my son hit missiles and balls over the fence on the first day. Expensive, but worth it for avid players.

**CONS**



* Great indoor results with the new non-Easton bat during coach pitch pre-season. Disappointing mid-season pop-up infield hits. I've always used Easton before, won't try other brands again.
* Great pop, but poor performance when missing sweet spot. Treated with care, but still cracked in Apr. Son upset I didn't allow use in cold weather, with heavy balls or pitching machines. It was mostly used as game bat last year, did not last into 2nd season.
* My son's bat barrel cracked after hitting his first HR, leaving him without a bat during All Stars and elimination series.


### **Certification**: BBCOR, USA, USSSA


### Expert Notes (Parker)

The DeMarini CF is a classic model that goes back to 2015 and offers one of the hottest models (2017) but is limited in use as its performance surpasses bat standards. Overall, the CF reflects a classic design which has been the same since 2015. A two-piece composite that offers a large barrel and sweet spot with a lightweight handle that creates a whip-like feel to it with the flexible connection between the handle and barrel.

### 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.

### 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.
