5 inning rule.

[BDUGAN]

PLEASE CLARIFY THE 5 INNING RULE AND WHAT HAPPENS WHEN THE TRAILING TEAM PULLS WITHIN TWO RUNS. IT IS MY UNDERSTANDING THAT PLAY CONTINUES BUT THERE HAVE BEEN CIRCUMSTANCES THAT A TEAM CAN WIN BY ONE POINT. WHAT ARE THE SPECIFICS FOR REQUIRING PLAY TO CONTINUE. THESE WOULD BE USSAA RULES.
