BBCOR stands for Bat-Ball Coefficient of Restitution. This new rule is designed to make non-wood bats even more wood-like in their performance. All BBCOR bats can be easily identified by the BBCOR mark. All bats used this season must be on the BBCOR approved list.
No BESR bats will be allowed. Bats must meet the BBCOR standards (including ABI procedure). A mark (decal, stamp or silkscreen) must appear that indicates the bat is BBCOR compliant.
