The International Tiebreaker rule (with outs modification):
The last batter of the current inning will be placed on second base with 1 out. The next individual in the lineup will be placed at bat and play will continue from that point. This will continue until a winner is determined.
The tie breaker rules ONLY APPLY to tournament games on Sunday, not pool play games on Saturday. Saturday games can end in a tie at the end of regulation (Innings or time limit apply).
