From the By-Laws :
In the event of a tie in the final standings, the involved team’s records will determine the tie breaker as follows:
A) most wins
B) records against each other
C) combined scores against each other
D) Toss of the coin, except if the teams involved in a tie are in fourth place. In that case, they will play one seven (7) inning game on the first Saturday following the regular season on a neutral field. The home team is to be determined by the above method.
