The official bat in ASA Championship Play must meet all of the requirements of Rule 3, Section 1 and:
must bear either the ASA approved 2000 certification mark or the ASA 2004 certification
mark, and must not be listed on an ASA non approved list, and
must be included on a list of approved bat models published by the ASA National Office; or
must, in the sole opinion and discretion of the umpire, have been manufactured prior to 2000 and if tested, would comply with the ASA bat performance standards
then in effect.
Beginning January 1, 2004, all bats in ASA Championship Play must pass the ASA 2004 bat standard. All bats having the 2004 certification mark will be allowed in
ASA Championship Play. Bats that have the 2000 certification mark will not be allowed in ASA Championship Play unless they are listed on an approved bat list on the ASA website. For
convenience, the ASA website has a listing of bats that do not pass the ASA 2004 bat standard.
