Bat Leagues & Certifications
When choosing a baseball bat for your upcoming season, one of the first things you should look at is your league's National Governing Body. The three most common governing bodies for bats are USA Baseball, USSSA and BBCOR. Every league, regardless of age, will follow a specific bat standard for their equipment regulations. The Bat certification logo will always be stamped somewhere on the barrel or taper of the bat. Be sure to check with your local league prior to purchase to ensure your bat meets league requirements.
