Metro High School Rules
15 run rule after 3 innings and 10 after 5.
Section 3, B: The fifteen-run rule at the end of three innings and the ten-run rule at the end of five innings will be in effect.
Suspended/called game must be played over again if the game is not complete (less than 4 ½ innings)
Section 9, B: All varsity contests that are called (because of weather) before they are considered completed will be replayed from the beginning. A completed game is 4 1/2 innings if the home team is leading, and 5 innings if the visiting team is leading.
Rainouts need to be played the next available day for both teams – league games trump non-league.
Section 9, A: Games postponed because of inclement weather shall be rescheduled for the first open date. The only valid reason for not rescheduling is unavailability of umpires, transportation or facilities conflicts
Sportsmanship – there is a run rule for a reason. Please remember the bigger picture here which is keeping student-athletes involved and connected to their school. Beating up on a lesser team does nothing for you as a team and only hurts the kids on the other end, eventually making it easy for them to quit. When we lose teams YOU lose your allocations to playoffs, including state. Remember why you are coaching – you are teaching your student-athletes life lessons and I hope one of them is compassion and grace.
Lightning and Thunder policy per WIAA:
WIAA- Lightning Guidelines- When thunder is heard, or a cloud-to-ground lightning bolt is seen, the thunderstorm is close enough to strike your location with lightning. Suspend play and take shelter immediately. Once play has been suspended, wait at least 30 minutes after the last thunder is heard or flash of lightning is witnessed prior to resuming play. Any subsequent thunder or lightning after the beginning of the 30-minute count, reset the clock and another 30-minute count should begin.
