Official betting is a bit more complicated than other team sports, as baseball games often get shortened or called early for weather reasons. As a rule, most wagers will be void if a game is terminated before the first pitch (unless it resumes the same day and becomes official at that point), but there are some exceptions. In particular, full-game moneylines become official at five innings, while total bases props are settled based on the 6.5 innings rule for 7-inning games (unless otherwise noted).
Player Props
A player must be in the starting lineup and the game must be official for any player-prop bets to have action. Unless otherwise noted, all player-props are rounded to the nearest whole number for settlement purposes. Similarly, any head to head player-specific bets must have both players in the starting lineup for the wager to have action.
Series Betting [Regular Season] – All scheduled games in the series must be played for all bets to have action, except in the event of an American/National League Wildcard game being won by the team(s) that advance to the playoffs. In the event of a game being won by the team(s) in the Wildcard game(s), all bets on the Series Over/Under will stand.
