### 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.

### Product Description 

The Louisville Slugger Solo 618 (-3) is a BBCOR certified bat with a 2 5/8 inch barrel diameter. This is a one-piece, aluminum alloy bat that’s permitted for use at both the high school and collegiate level. Specifically, this bat features the lowest swing weight profile and the fastest swing speed of any bat in Louisville Slugger’s BBCOR lineup. Lastly, the handle features anti-vibration technology to help reduce sting on mishits. In addition, it comes with a custom lizard skin grip to give you exceptional comfort.

### Expert Notes

It is the most balanced bat Slugger makes, and by sure features the lightest swing of all Louisville Slugger bats. It also comes in a 29-inch length, which we absolutely love. The 618 Solo in BBCOR is one of the best BBCOR bats on the market. It’s a perfect option for a 13 or 14-year-old looking for as much bat speed as possible. It also has a good sized barrel and enough girth to avoid major hand stings on mishits.
