Baseball Rules
Date/Site Changes
Regular season Baseball games must be played on the scheduled date/location (location is a geographical area or city, but not restricted to a specific arena or venue) to be considered action unless otherwise noted in the specific sports rules section or the inventory game page within the mobile application or web browser application.
Minimum Length of Play
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.
Live Wagers: Game must go full scheduled length to have action on all markets: 9 innings (8 ½ if the home team is ahead) for 9 inning games, or to 7 innings (6 ½ if the home team is ahead) for 7 inning games. If the game is called before this time then all bets will be void, except for those that have been unconditionally determined.
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 money line, totals, and run lines, game must go the full specified innings.
All baseball propositions are considered action regardless of any pitching changes.
Baseball Wager Rules
Baseball wagers are accepted in the following manner:
One specified pitcher: A wager on or against one specified pitcher, regardless of the other starting pitcher. Specified pitcher must start or wager is deemed “no action” and wager is refunded.
Both specified pitchers: A wager that specifies both starting pitchers must start for action. Any variation constitutes “no action” and wager is refunded.
*In the event of a pitcher(s) change prior to the start of a baseball game, money line odds will be adjusted to the opening price of the new pitching matchup.
Note: Each team’s starting pitcher is defined for wagering purposes as the pitcher that throws the initial pitch.
Money Line: A wager in which the bettor “takes” or “lays” a specified price. The team wagered must only win the game for the wager to be deemed a winner. Extra innings are counted in final score. Money line wagers are for team against team, regardless of the starting pitcher, unless the team option with both pitchers listed is specifically selected at the point of bet placement - in which case any subsequent change to either starting pitcher will be considered ‘no action’ and the wager will be refunded accordingly Wager must meet the minimum length of play as specified above.

Baseball Proposition Rules
Various unique wagers may be offered from time to time. When wagering proposition bets, the game must go 9 innings (8 ½ innings if the home team is ahead) to have action, or action has occurred as the outcome of the wager is already known. If a game is suspended after 9 innings (8 ½ innings if the home team is ahead), the final score is determined 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 score is determined by the score at the time the game is called. All baseball propositions are considered action regardless of any pitching changes.
For the above, if a game is scheduled for only 7 innings, then game must go 7 innings (6 ½ if the home team is ahead)
Baseball Player Props
Players in player prop bets do not have to start but must play some part for Player Props to have action. Wagers on specific player performance or match wagers will be deemed official once at least one of them have left the game, with both having taken some part in the game to that point, regardless of the conclusion of the game.
