[/FONT][/FONT]EFFECT – If a batter enters the batter’s box with an illegal bat (one that does not meet NCAA specifications), upon discovery, the bat shall be removed from the game (i.e., not returned to the dugout) the batter shall be declared out and base runners shall not advance. If the batter enters the batter’s box with an altered bat (one that enhances performance by being structurally changed); the penalty for an illegal bat shall be imposed, in addition, to the batter being ejected from the game.
