2016 list of non-approved bats
In 2013 the ASA introduced a new certification mark for slowpitch bats. However, this does not mean that the previous marks from 2000 or 2004 are obsolete.
So all bats that have an ASA mark, or the current ISF certification mark are legal as long as they do not appear on the current ASA non-approved bat list.
These marks are also recognised as the ESF standard.
Please note that the ASA non-approved bat list is liable to change at any time. The ASA has a rolling programme of bat testing and bats may be added to the list during the season. This is out of the BSF’s control, and can be checked on the ASA website.batlist_0716
