The Minnesota Metro Fastpitch league, NAFA, and ASA rules mandate that players should utilize approved bats during league play. When purchasing a bat, look for the ASA 2004 certified, NSA 2012, and USSSA stamp. Bats without these stamps will not be allowed during league games and tournaments and may result in disqualification. Players that do not have access to an approved bat may utilize other teammates bats. However, it is recommended all players purchase their own bats. Below is a photo of what to look for when purchasing a bat.
