Regular season Baseball games must be played on the scheduled date and at the listed 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.
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.
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.
Baseball Wager Types
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.
Total Runs (Over/Under)
A wager on whether the total number of runs scored in a game is over or under a specified number. Extra innings are counted in final score. Wager must meet the minimum length of play as specified above.
A wager in which the bettor “takes” or “lays” a specified number of runs. The team wagered must “cover” the run line for the wager to be deemed a winner. Extra innings are counted in final score. 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. If a game is scheduled for only 7 innings, then game must go 7 innings (6 ½ if the home team is ahead)
All baseball propositions are considered action regardless of any pitching changes.
Hit(s): BetMGM settles markets in accordance with official box score statistics declared by MLB as the governing body.
Baseball Player Props
Players that are the subject of a player prop wager must start for the wager to have action. Specifically, wagers on a position player’s performance will be considered action once the player has a had a plate appearance. Further, wagers on a pitcher’s performance will be considered action once that pitcher has thrown a pitch for their team. For any player v. player propositions, both players must start the game and have an official appearance as set forth above for the wager to have action. Further, these player v. player wagers will be deemed official once at least one of the players has left the game, regardless of the ultimate outcome and/or completion of the game. Except as specified above, all games must be played and considered an official game by MLB for bets to have action. MLB games are subject to weather postponements, where a game can start and then be stopped due to inclement weather and then moved to another date. BetMGM will void all player proposition wagers when a game is postponed in this manner. However, BetMGM will not void player proposition wagers that have been unconditionally determined at the time of the postponement.
For MLB in-play props, BetMGM will void wagers if a bet is placed on a market for a player who is subsequently taken out of the game before they are able to accrue more stats. For a wager on a batting market for position player, this would be where the player does not make a subsequent plate appearance after the bet was placed. For a wager on a pitching market for a pitcher (or a batting market for a pitcher in the case of National League pitchers), this would be where the pitcher does not throw another pitch after the bet was placed.
Baseball Regular Season Series Props
Regular season series props are offered for all 3, 4 or 5 Game Series with the outcome of the all games played counting towards settlement. Series must go a minimum of 3 games for action regardless of games scheduled and or canceled. A called game will count towards a series wager if declared an official game by the league. All wagers are action regardless of Starting Pitchers or pitcher changes.
Baseball Playoff Series Props
For Playoff Series Winner props, the team that advances to the next round is deemed the winner. Wagers for all other markets are refunded if the required minimum number of games (according to the respective governing organizations) are not completed, or the number of games changes.
Baseball Post Season Rule
All MLB playoff games will have action regardless of date played and/or completed, unless specified otherwise. Game winner will be paid based on the official winner of this game as determined by MLB. All listed pitchers’ rules apply.
Baseball Grand Salami Props
Grand Salami prop is determined by the total runs scored in all MLB games scheduled for that day. There are no listed pitchers so all bets are action. Wager applies to all scheduled games and games must go 9 innings (8 ½ if home team is leading). If any game is cancelled or stopped before the completion of 8 ½ innings, all wagers on the Grand Salami will be cancelled. Grand Salami will not be offered when 7 inning games are scheduled
Baseball season long futures are unique wagers which will be offered from time-to- time. For all season long and future props, all wagers stand regardless of team re- location, change to a team name, season length or play-off format unless stated otherwise in the market.
