The Amateur Softball Association of America (ASA) is the National Governing Body of Softball in the United States. As part of the ASA Bat Testing and Certification Program, bats submitted for testing are issued an ASA certification mark if the model satisfies the ASA Bat Performance Standard. ASA routinely and randomly audits compliance with the ASA Bat Performance Standard by testing samples of certified bats. In addition, ASA takes efforts to ensure that the ASA certification mark is not being used on bats that are not certified. Until further notice otherwise, bats of the following models containing an ASA certification mark are no longer allowed in ASA Championship Play unless they contain the following ASA recertification mark:
