When betting on baseball…
Baseball games are considered official after 5 innings of play (4½ if the home team is winning). If a game is called or suspended after 5 innings, the winner is determined by the score after the last full inning of play – unless 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 called. When betting on baseball totals or run-lines, the game must go 9 innings (8½ if the home team is winning).
