Here are the rules according to OLY:
A baseball game becomes official for moneyline wagering purposes after 4 1/2 innings if home team is winning, or 5 innings if visiting team is winning.
If a game is cancelled or suspended, the winner is determined by the score after the last full inning (unless the home team scores to tie, or takes the lead in the bottom half of the inning, in which case the winner is determined by the score at the time the game is called).
Money will be refunded if the home team ties the game, and the game is then suspended.
Events do not carry over to the following day (unless otherwise specified).
For runlines and game totals (over/under), a baseball game becomes official after 8 1/2 innings if home team is winning, or 9 innings if visiting team is winning.
Not sure how that gives me a loss on the Cubs.
