Atlas Alloy

# Louisville Slugger Atlas Baseball Bat

The Louieville Slugger Atlas Bat is a premium one-piece alloy masterpiece for elite high school and college players. Boasting an updated look and crafted through both player trials and AI simulations, this bat combines cutting-edge technology with the legendary history of Louisville Slugger bats. 

The Atlas leverages insights from AI modeling to incorporate variable barrel thickness along its entire length, resulting in a colossal sweet spot and optimal performance. With a one-piece alloy design, this bat offers total barrel control and a comfortable feel, carrying forward the legacy of Louisville Slugger's dedication to the art and science of the game.

**Perfect bat for:** Players who prefer a light swing weight or a wood-like feel in an alloy bat. It's a precision hitter’s bat designed to provide a good balance between weight and power.


### Key features include:



* **EVOKE Alloy Barrel:** AI-optimized wall design along the entire length of the barrel.
* **SPD-Gen2 End Cap:** Designed with lightweight, composite materials to optimize barrel performance.
* **Premium LS Pro Comfort Grip:** Applied to the handle for the added tack and cushion players love, improving comfort and bat control.
* **Balanced Swing Weight:** For the ultimate combination of speed and power
* **TUNED Mass Damper (TMD):** Component within the handle absorbs vibration.
* **One-Piece Alloy Construction:** Stiff, durable design focused on amplifying a player’s bat speed to deliver peak exit velocities.


### Top competitors comparison: The [Voodoo One](https://sidelineswap.com/shop/baseball/bats/demarini/voodoo-one/l9487) and [Easton Alpha ALX](https://sidelineswap.com/shop/baseball/bats/demarini/voodoo-one/l9487)


The Voodoo One, Easton ALX, and Louisville Slugger Atlas, all light-swinging single-piece alloy baseball bats, offer distinct advantages for hitters. The Voodoo One emphasizes precision and durability with a balanced swing, while the Easton ALX focuses on a responsive sweet spot and lightweight feel. The Louisville Slugger Atlas, incorporating AI simulations, stands out with variable barrel thickness for a massive sweet spot and optimal performance, carrying the historic legacy of the Louisville Slugger brand. Each bat caters to different player preferences, with the Voodoo One and Easton ALX providing reliable performance and the Atlas introducing technological innovation for elite high school and college players.


### The progression of the Louisville Slugger Atlas Baseball Bat:

There is no 2022 version of the Atlas. It’s compared to the single-piece Solo which also used a variable wall thickness and unique end cap to keep the bat light. 


### What people are saying (edited for clarity and brevity)


**PROS**



* My 14-year-old son needed a new BBCOR bat. He likes the one he got as it swings light and the barrel seems huge, although it's very loud.
* My son has been swinging a Cat X composite. I was not seeing the bat speed I thought he should have by now, I bought him the Atlas and from the first swing I saw a difference on bat speed. 
* Balanced bat with a massive sweet spot which makes it easy to catch barrel. As well as great improvements in durability.

**CONS**



* Loudest bat especially in cages. Bat has a rattle in it and we have only had it 3 months.
* The bat has so much vibration.
* Way to loud. It's distracting.


### Certification: BBCOR, USSSA, USA


### Expert Notes ([Tony](https://sidelineswap.com/locker/batexperts))

The Louieville Slugger Atlas is a newer bat that's been out for two years now. It's the next bat in the same generation as the Louisville Slugger Solo. It is a one-piece design, very easy to swing. Flashy paint job. It’s one of the top couple of bats in the alloy market.

### 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.

### 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**



* 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.

**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.

### Progression of the Rawlings Quatro Pro Baseball Bat 

Here is a list that details the progression of this series, highlighting the main features and advancements with each new model. 
 
**2019 -** **[Quatro Pro](https://sidelineswap.com/shop/baseball/bats/rawlings/quatro-pro/l10010)**

- Maintained the critical features of balance, reduced vibration, and Flex Barrel technology. 
- Improved weight distribution for an even more balanced feel. 
 
**2021 -** **[Quatro Pro BBCOR](https://sidelineswap.com/shop/baseball/bats/rawlings/quatro-pro/bat-type-bbcor/l208035)**

- New Lizard Skins grip for improved handle feel and comfort.

### What people are saying (edited for clarity and brevity)

**PROS**



* I initially bought the end-loaded Pro Max bat, but it failed the NCAA bat testing. So, I tried the Quatro Pro bat and was surprised by its pop, even though it sometimes feels too light. 
* If you are searching for a composite bat that offers balance, then this bat is a fantastic choice.
* The Quatro Pro has a lot of pop and zero vibration. It has a good sweat spot and is all-around a good bat.

**CONS**



* My son enjoyed using the Rawlings bat and liked the popping sound. However, the knob broke off after only six months of use. We contacted Rawlings and they sent us a new bat as a replacement. Unfortunately, the knob on the new bat broke off again after just three months of use.
* Small sweet spot and weird swing weight
* Rawlings 2-piece bats are inferior quality they break easy and can’t withstand use over time. 


### **Certification**:

USA Baseball, USSSA, and BBCOR


### Expert Notes ([Tony](https://sidelineswap.com/locker/batexperts)) 

The Quatro Pro launched in 2019. Even today, it's one of the hottest bats out there. If you can find one, the Quatro Pro is a great performer; it is lightweight, easy to swing, and has a ton of pop. Probably one of the top five BBCOR bats of all time. 

The first two years had breakage issues. Since then, Rawlings has made some adjustments to the barrel, thickened the sidewalls and made the bat more durable, but in doing so, they lessened the performance. The later models are not as popular as the early ones.
