What ruling applies if a batter enters the box with a non-wood bat that has a BESR certification but no BBCOR certification?

A batter is required to use a bat that meets specific certification standards to ensure fair play and safety during a game. In high school baseball, the most current standard governing bat usage is the BBCOR (Batted Ball Coefficient of Restitution) standard. A non-wood bat may have a BESR (Ball Exit Speed Ratio) certification, but that standard was phased out for high school play. Since the bat does not have the current BBCOR certification, it is deemed illegal for use in a game.

As such, if the batter enters the box with a bat that lacks the BBCOR certification, it is considered a violation of the rules, and appropriate penalties are enforced. This serves to prioritize player safety and maintain the integrity of the game. Hence, using a bat that fails to meet current certification requirements leads to the conclusion that the bat is illegal, resulting in the enforcement of penalties.
