This page is created so that there is no question as to what bat is legal or illegal. Also I have added the page for Grandfathered bats and a powerpoint display on doctored bats. Please look at this information and also keep a copy so that when questions arise you will have proof of your bats legality.

 ASA Bat Testing & Certification Program

The official bat in ASA Championship Play must meet all of the requirements of Rule 3, Section 1 and:

1. must bear either the ASA approved 2000 certification mark or the ASA 2004 certification mark as shown below, and must not be listed on an ASA non approved list, and
2. must be included on a list of approved bat models published by the ASA National Office; or
3. 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.

2004 and Beyond Approved Bats (Updated:5/15/2009)

For a list of bats that have been tested and found to comply with the ASA bat performance standards, and therefore are authorized to bear the ASA 2004 certification mark and/or are authorized for use in ASA Championship Play beginning January 1, 2004, please click on the manufacturer below. Manufacturers continue to submit additional bat models for testing, and the ASA will update this list as test results become available.
