Participants are assigned to a real baseball team to represent them. It's best to choose random MLB teams for each participant. Win or lose, each teams run total at the end of the game is recorded. The winning team of the pool must record every run from 0 to 13 in the least amount of games played.
A team is not declared the winner until it has recorded every run from 0 to 13 in less games than any other team. If the winning team has played more games than those teams beneath them, this team should not be declared the winner until each team has played those remaining games. For example, if Minnesota got their last run in their 62nd game, but Colorado has only played 60 games, its still possible for Colorado to win.
Ties are very unlikely, but possible. If multiple teams record their last run with the same amount of games played, the winner is the team that finished on the earliest date. For example, if Minnesota got their last run yesterday in their 62nd game, but Colorado needs one more run and has only played 61 games, the best Colorado can achive is a tie with Minnesota where Minnesota has the tiebreaker.
If multiple teams record their last run with the same amount of games played on the same day, split the win.
Run totals only count on the day where they were official recorded.
Normally, only the 162 regular season games are counted. However, you can optionally include official preseason games. Post-season and exhibition games should not be included.
Each participant should pay equal amounts for a single entry to the pool and the winner receives the pot. If there are less than 30 participants, participants are permitted pay for addition entries at the same cost. Teams can also be left owned and ignored as potential winners.
If no team has finished when the season ends, the pool should carry on into the next season.
