NFHS Case Book

7-3-1 Situation D

B1 steps out of the batter's box (a) without requesting time... RULING: In (a), the umpire shall call a strike if he feels B1 delayed the game.

7-3-1 Situation F

B1 has a count of three balls and one strike. In (a), F1 throws a pitch which B1 thinks is ball four and he starts running to first base prior to the umpire calling the pitch a strike or (b) B1 incorrectly thought the count was two balls and two strikes and heads to the dugout after the umpire called the pitch a strike.
RULING: In both (a) and (b), as long as the umpire judges that B1 did not delay the game, he would be allowed to continue to bat with a count of three balls and two strikes. If the umpire felt that the game was delayed, he shall charge a strike to B1. Because of the additional strike which now has been called, the batter is declared out in both (a) and (b).

The batter, in the judgment of the umpire, must delay the game. He has not in original post. He has been hit by the pitch. He goes to first base.
