I found this in the rules for the tupe-up:
FORMAT: 7 game tournament pool play format. To determine tournament winners, you will receive 2 points for each win, 1 point for a tie, and 0 points for a loss. At the end of the tournament, the total number of points divided by number of games played will determine the winner (minimum of 4 games). All teams in each age bracket will be considered one pool. If a team plays more than 7 games, only the scheduled games will count.
TIE BREAKERS:
1) Head to head competition
2) Number of runs allowed
3) Coin flip
