Tim: For all side bets, a game is considered official after five innings of play (four and a half if the home team is winning). Thereafter, if a game is canceled or suspended the winner is determined by the score after the last full inning of play. If the home team scores to tie or takes the lead in the bottom half of the inning, the winner is then determined by the score at the time the game is canceled.
