Pre-Game Wagers
Unless otherwise stipulated in individual Baseball sports wager rules, wagers on baseball money lines are official after 5 innings of play. If the home team is leading, the game is official after 4 ½ innings (this will include softball). Thereafter, 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 take 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.
For games scheduled to play a full 9 innings, game must go to 9 innings (8 ½ if the home team is ahead) to have action on run lines and totals. For games scheduled to play only 7 innings, game must go to 7 innings (6 ½ if the home team is ahead) to have action on run lines and totals.
In specified inning wagers, game must go full specified innings to be official, unless the home team is leading the bottom half of specified inning prior to completion of specified innings(s). For moneyline, totals, and run lines, game must go the full specified innings.
