Additional ASA Certification Information

The ASA established their current Fastpitch Softball Bat standard after two years of testing both in the field and in the laboratory - it is called the ASA 2004 Standard.

The standard focuses on the ball exit speed - the speed of a pitched ball after it has been hit with a bat. This speed MUST be less than 98 MPH and must meet the Bat Performance Factor standard of 1.20 (BPF-1.20).

All Fastpitch Softball Bats meeting these standards will be stamped with the new ASA 2004 certification logo.

Some Fastpitch Softball Bats have an exit speed greater than 100 MPH - these Fastpitch Softball Bats are illegal for ASA play.
