What is the quick review?

The 2021 Louisville Slugger Solo is a light swinging single piece aluminum bat made for the performance BBCOR and USSSA space. There is no 2021 version for USA. The major changes are the re-engineered barrel design of the 31 through 34-inch BBCOR and new end cap to help bring down swing weight in the USSSA versions.

What models and sizes are available?

Our hitters like the light swing, big barrel, and solid performance of the 2021 Louisville Slugger Solo. In BBCOR, smaller players looking for as much bat speed as possible but are also comfortable enough with their skills to prefer single piece bats liked the Solo a lot. For USSSA, the drop 5 was preferred more than the other versions for bigger hitters. Most smaller players preferred the lighter swing of two-piece composite bats like the Meta or CF, but did just fine when it comes to exit speeds with the Solo.

How is it built?

The 2021 Louisville Slugger Solo is a single-piece bat with thin alloy walls to help bring down the swing weight. The bat is stiff, has a decent barrel profile, and uses a grip stock straight from Louisville Slugger.

How does it compare?

The major change from the 2020 Solo to the 2021 Solo is the retooled alloy on the 31 through 34" BBCOR versions of the 2021 Solo. The bat lost a bit of luster in its bigger sizes as its swing weight was still moderately balanced instead of light. But, this new alloy helps bring down the swing weight and keeps it a true light swinging bat across all sizes. In USSSA, the new end cap doesn't make much of a difference, as far as we see it. It likely helps Slugger keep the swing weight down a bit, but nothing our hitters noticed.
