First of all, I'm glad I'm our area Big League director where MP isn't an issue!
Secondly, I'm looking at the tournament rules which does differ slightly.
A game is NOT considered shortened if the home team does not complete the bottom of the 6th or 7th inning due to winning the game. Maybe I'm reading too much into this, but if the game only goes 4 or 5 innings, they did not complete the 6th or 7th due to winning the game. According to the way I read it, that doesn't count as a shortened game and in tournament play is grounds for protest and forfeiture. In regular season? That's supposed to be made up the next game as you wrote and I vew that as a local league problem rather than a district problem.
Are we in agreement with that?
