If a pitcher brings his hand to his mouth and wipes it off while touching the pitcher's plate, what is the outcome?

When a pitcher brings their hand to their mouth while touching the pitcher's plate, this action is deemed illegal according to NFHS rules. The act of the pitcher wiping their hand on their mouth can be interpreted as introducing a foreign substance or moisture to the ball, which can affect the game's fairness and safety. As a result, such an infraction calls for a penalty, specifically adding a ball to the batter's count. This rule serves to maintain the integrity of the game by preventing any potential unfair advantage that the pitcher might gain through the use of saliva or any substance that may alter the ball's properties. The other options are not applicable in this scenario because the issue at hand relates specifically to a violation of pitching conduct that leads directly to a modification of the batter's count.
