What is the BBCOR Certification?

What is the BBCOR Certification?

BBCOR (Bat-Ball Coefficient of Restitution) is something you've probably heard a lot about recently; it's the new standard currently governing adult baseball bats used in collegiate play, and it will be implemented for high school play in 2012. Rather than measuring the ratio of the ball exit speed to pitch and bat speeds (like with BESR), BBCOR measures the trampoline effect of the bat. In the past, when a pitched ball made contact with an alloy or composite bat, the barrel would flex inward ever so slightly and the ball would retain some of its energy resulting in farther hits. Wood bats don't have as much "give" to them and the ball loses much of its energy upon impact. The BBCOR standard ensures that non-wood bats perform more comparably to wood bats in an attempt to level the playing field.

What Happened to BESR?

Ball Exit Speed Ratio (BESR) is the standard that formerly governed adult baseball bats. BESR is found by finding the ratio of ball exit speed to the combined speeds of pitched ball and swung bat.
