Here's the rule from the Pinnacle web site-
4. The result of a game is official after 5 innings of play unless the home team is leading after 4.5 innings. If a game is called 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. Monies will be refunded if the home team ties the game and it is then suspended. Events will not carry over to the following day unless otherwise specified.
