Question: what is the difference between bbcor and usssa bats?
Answer: The BBCOR standard put on high school baseball bats in 2012 really dampened down the pop of -3 high school bats. Most BBCOR bats actually have something called a 'restrictor ring' in the barrel to prevent trampoline effect and springiness in the barrel. ... On the other hand, a USSSA 1.5 BPF bat has a lot more freedom.
