Marucci CAT9 Baseball Bats

Players who are looking to elevate their game with superior balance, power, and performance.

Perfect bat for: 

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 players. 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. 

Tony from BatExperts

The Marucci CAT 9 is constructed of a single piece of aluminum and multivariable wall thickness to extend the length of the sweet spot and bring down swing weight. It’s 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 including an AV2 knob which helps dampen sting on mishits. The Marucci CAT 9 comes in BBCOR, USSSA and USA models.

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

Progression of the Marucci CAT 9 Baseball Bat

The Marucci CAT9, known for its massive sweet spot and great sound (aluminum), offers a balanced swing weight for a traditional feel at a competitive price. The Easton ADV 360, a top performer with a large sweet spot (composite), prioritizes power for aggressive hitters with its innovative Launch Comp technology, but lacks the durability of aluminum bats. The Louisville Slugger Solo (aluminum) boasts a balanced swing weight and a forgiving feel on contact, making it a great all-around option for players who value control at a more budget-friendly price.

### 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.
