Question: what is the difference between bbcor and usa bat?
Answer: BBCOR certification regulates adult bats performance and BBCOR measures the trampoline effect of the bats. These bats are made only in a drop 3 (-3) or minus 3 and have 25/8'' Barrel. On the other hand, USA baseball bats are designed to perform like BBCOR bats but don't have drop weights restrictions as in BBCOR balls.
