In order to maximize playing time, and decrease "down time" during games, the following game procedures will apply to all MBI league games:

1.  There will be NO pre-game warmups permitted on the infield area.  All warmups will take place in the outfield area.  This will eliminate the possibility that one team might get more infield warmup time than the other.  Once the umpires have arrived they will conduct the pre-game managers meeting at home plate, then they will instruct the home team to take the field.  For 9U and above, the home team pitcher may then take the mound and begin his/her warmup pitches.  The first warmup pitch is the official game start time.  The visiting team should have their first batter ready to enter the batter's box immediately upon completion of the pitcher's warmup pitches..  In T-Ball and Coach-Pitch games, the umpire will announce the start of the game.

2.  New pitchers (starting pitchers and relievers) will be allowed 8 warmup pitches from the mound upon entering the game.  Between innings, a pitchers who pitched the previous inning will be allowed 5 warmup pitches from the mound. 

3.  When games are running late, teams playing next should be prepared to start ASAP after the prior game ends.  (Keep in mind that the umpires do get a short break between games to change gear)

4.  On MISD school nights, no late game (last game of the night on a given field) shall begin play if the game which precedes it ends AFTER 8:45 PM.  In this case, the late game would be postponed and rescheduled.  This policy is in place to ensure that the last game of the night on a given field does not extend beyond a reasonable hour.  (This item does not apply to the 15U-18U leagues).

5.  After each game, teams and fans should clean up after themselves, both in the dugout, and the spectator areas.
