All Fastpitch softball bats must have a 2” barrel diameter and must not be over 34” in length and 31 oz in weight regardless of which association you play in.
Bats must be marked with the ASA Certified 2004 stamp. These Fastpitch bats should perform within the limits of the 98 mph batted ball speed standard. Bats can be made from aluminum or other metals; fiberglass, graphite or other composite material; or wood. Bats can be made from one or multiple pieces.
You can find additional information on ASA's Certified Equipment page.
Bats may not exceed a Bat Performance Factor (BPF) of 1.20. This should be marked on most, if not all, USSSA Approved Fastpitch bats. Bats can be made from aluminum or other metals; fiberglass, graphite or other composite material; or wood. Bats can be made from one or multiple pieces.
Check out USSSA's Equipment Rules for more information.
ASA is considered the most highly regulated association in softball, followed by USSSA. If your Fastpitch softball league is governed by a different body, the chances are that if your bat bears the approval of either ASA or USSSA, it will be legal in your league. However, it is always a good idea to check with your league's website or director for specific rules, regulations, and lists of approved bats.
