The Atlas is a one piece alloy BBCOR bat. On the WSU certified list it appears in lengths 29, 30, 31, 32, 32.5, 33, 33.5, and 34 inches. The shorter lengths help smaller players moving to drop 3; a 29 inch BBCOR bat weighs about 26 ounces.

Alloy bats need no break in and handle cold better than composites, which matters for spring ball in northern states. They usually sting more on mishits than two piece bats. Because BBCOR caps performance for every bat, the gap between bats is smaller than the prices suggest.

Louisville Slugger also has a 2027 Atlas 2.0 (BBAT2B3-27) on the WSU list. It is a different model number, so check which one you are buying.

The Bottom Line

A one piece alloy BBCOR bat: no break in, better in cold weather than composites, and sizes from 29 to 34 inches.
