Fast Pitch Bat Standards from Softball Canada
We have received several inquiries about the new Fast Pitch bat standards. As stated in the standards...
Any bat that appears on the ISF Approved Bat List and has an ISF certification stamp will be accepted for play at a Softball Canada event
Any bat that appears on the ASA Approved Bat List and has an ASA 2000 or 2004 certification stamp will also be accepted for play at a Softball Canada event....
For Fast Pitch purposes the ASA 2013 stamp can be ignored. This means that any bat that has an ISF, ASA 2000 or ASA 2004 stamp is legal, regardless of whether or not it has an ASA 2013 stamp.
