## DeMarini CF Baseball Bat


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)

The DeMarini CF stands out with its exceptional use of Paraflex Plus Composite and 3Fusion Connection technology, which provides a perfect blend of feel, flex, and performance. 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.

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.

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.
