Softball Regulating Bodies

When you receive your new bat, one of the first things you do is probably inspect it. During your softball bat inspection process,  you probably notice some acronyms like ASA, USSSA, ISA, NSA and WBSC.

Even though these governing bodies may follow similar guidelines and rules each governing body is separate from the others. Therefore, you must adhere to that specific governing body pending your league or tournament play. No matter what governing body you play under there are more similarities than differences. Every organization has a set of rules which promote consistent, fair, and safe play. One of the most interesting differences is in the certification of bats.

USSSA and NSA also test bats for certification. Those associations use a test developed by Dr. Brant, a physics professor at New York University. This test, as attested by many players, allows for greater ball acceleration off the bat. On the field, we might say these bats have more pop. Some people, possibly erroneously, have referred to these softball bats as 100+ mph bats.
