My "favorites":
SITUATION 14: With a lazy, one-hop single to the right fielder, the batter rounds first base with no intention or action of advancing to second base. As he takes a few easy strides past first base, he contacts the first baseman who is partially in his path. RULING: Since the batter was making no attempt to advance to second base, the first baseman did not hinder him or change the pattern of the play. As a result, obstruction would not be called. Any benefit of the doubt would be given to the batter-runner if there was a question in the covering umpire's mind. (3-22-1)
SITUATION 15: With the pregame conference ready to begin, the home team head coach is in the bullpen and refuses to attend. He sends his assistant coach and a captain to be present. The assistant coach provides his team's lineup and verifies to the umpire-in-chief that his team is properly equipped. RULING: The umpire-in-chief will accept the assistant coach's verification and conclude all needed activity at the pregame conference. The head coach will be restricted to the dugout for the remainder of the game. (3-2-4 Penalty, 4-1-3a)
SITUATION 19: The umpire-in-chief notices that the head coach coaching at third base is not in the coach's box. The coach is not gaining an advantage or causing any problems. RULING: There is no violation. If the umpire believes that the coach was gaining an advantage for his team, he would require the coach to be within the confines of the coach's box. (3-2-1)
SITUATION 20: With the bases empty, the visiting team is at bat and the assistant coach in the first base coach's box is wearing a dual flap helmet while the head coach in the third base coach's box is wearing a hard liner under his team cap. The home team coach complains to the umpire-in-chief that both coaches must wear the same type of protective helmet in accordance with MLB rules. RULING: The NFHS has not mandated that adult coaches shall wear protective head gear while occupying a coach's box. It is the prerogative of the respective coach to wear such protective equipment. The NFHS is conducting research to determine if protective head gear should be required and, if so, which type (hard liner, flapless, one-flap, dual flap) would be most effective. However, it is mandatory that when occupying a coach's box, a coach shall wear the team cap and that players/students wear a batting helmet that meets the NOCSAE standard and has dual ear flaps.
