If a batter enters the batter's box with an illegal bat, what happens?

When a batter enters the batter's box with an illegal bat, the ball becomes dead immediately. This is in line with NFHS baseball rules, which dictate that the use of an illegal bat is a violation that disrupts the integrity of the game. When it is discovered that the bat is illegal, the umpire's primary responsibility is to enforce the rules by calling the play dead to prevent any further action that could be influenced by the use of the illegal equipment.

Consequently, any actions taken with the illegal bat prior to the discovery can be nullified, ensuring fairness and compliance with the game's regulations. This process upholds the standards set forth for all players, maintaining a level playing field and preserving the sport's integrity. It is important to note that a dead ball situation prevents any advancement by runners on base as a result of the play initiated with the illegal bat.
