What is the ruling when a player enters the batter's box with a non-wood bat lacking BBCOR certification?

When a player enters the batter's box with a non-wood bat that lacks BBCOR certification, it is considered illegal for play according to NFHS regulations. The BBCOR (Batted Ball Coefficient of Restitution) certification is a standard that ensures bats perform similarly to wooden bats, which helps maintain fair competition and player safety at the high school level.

Since the bat does not meet these specifications, the proper ruling is that the bat is illegal. As a result, the batter is called out immediately because they attempted to use an improper piece of equipment during the game. This ruling emphasizes the importance of adhering to equipment standards in order to uphold the integrity of the game and protect players.
