### 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.

The CF series is DeMarini’s flagship line of composite bats, known for their innovative technology and exceptional performance for a wide range of players. The CF series combines comfortable contact, explosive power, and unmatched swing speed. Featuring Paraflex Plus Composite construction, the CF series has a large, light sweet spot, and its 3Fusion Connection dramatically reduces vibration and enhances weight distribution. 

**Perfect bat for**: Young players seeking a two-piece composite bat with maximum barrel control and pop.


### Key features include: 




* **Paraflex Plus Composite Barrel:** Engineered for consistent and responsive performance across a wide hitting area, enhancing pop and feel.
* **3Fusion Connection:** Reduces vibration and redirects energy back into the barrel, improving performance and comfort.
* **ReAction End Cap:** Increases barrel performance without compromising swing speed, optimizing the overall balance of the bat.
* **Two-Piece Construction:** Delivers a nice flex at contact, creating a whip effect that drives the ball with more force.



### Top competitors comparison: [Louisville Slugger Meta](https://sidelineswap.com/shop/baseball/bats/louisville-slugger/meta/l59403) and the [Easton Ghost X Evolution](https://sidelineswap.com/shop/baseball/bats/easton/ghost-x-evolution/bat-material-composite/l228675)

While the Meta is celebrated for its EKO Composite Barrel and balanced swing weight, and the Ghost X Evolution is recognized for its Dynamic Feel System, the CF shines with its ability to deliver a large sweet spot, reduce hand sting, and maintain a consistently high level of performance, positioning it as a top choice for players who prioritize comfort and power.

### 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.

### 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.

### 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.

## Marucci CAT9 Composite Baseball Bat

### Top competitors comparison: [DeMarini CF Zen](https://sidelineswap.com/shop/baseball/bats/demarini/cf-zen-2020/l8432) and the [Easton ADV 360](https://sidelineswap.com/shop/baseball/bats/easton/adv-360/l59709)

The Marucci Cat 9 Composite shines with its use of multi-directional composite materials, enabling a level of responsiveness and barrel performance that's hard to match. While the DeMarini CF Zen is praised for its consistently strong performance across the barrel and the Easton ADV 360 offers revolutionary 360-degree barrel tuning, the Cat 9 Composite distinguishes itself with a superior balance between speed, power, and comfort, courtesy of its meticulous engineering and vibration-dampening connection technology. This makes the Cat 9 Composite a top choice for youth players aiming to elevate their game with a bat that delivers fluidity and force in equal measure.

* When it doesn’t get hit on the sweet spot it doesn’t go very far and stings.
* It's a lilttle pricey and i already broke it... but i am going to buy a new one

### Expert Notes ([Tony from BatExperts](https://sidelineswap.com/batexperts))

The CAT9 Composite comes in two designs across two generations. The first, released in 2021, is gray, black, and red. And then it came out in red, white, blue, and gray. The first model was a more powerful, higher-performing bat. It has more exit velocity and is a hotter bat than the 2nd gen. Very durable, with very little breakage. Marucci's, across the board, have been good bats in terms of quality; they seem to last. Whether you're a power hitter or a small kid, the CAT9 Composite does very well.
