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
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.
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 Mercy Rule
If the game ends by the relevant league's mercy rule, then all wagers will be settled according to the results at the time the mercy rule is applied.
Baseball Wager Types
A wager that specifies the starting pitchers for both teams or either team. The name(s) of the listed pitcher(s) who are relevant for the wager will be included in the market name. If one or both starting pitchers listed on the wager does not start, the wager is cancelled.
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. Any starting pitchers listed in these selections are for informational purposes only. Wager must meet the minimum length of play as specified above.
Money Line Listed Pitchers
A wager that specifies the starting pitchers for both teams. The team option with both pitchers listed is specifically selected at the point of bet placement. Any subsequent change to either starting pitcher will be considered ‘no action’ and the wager will be cancelled 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.
For MLB in-play props, BetMGM will cancel 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.
Batter v. Batter Most on Base
Settled using the total number of walks, intentional walks, Hit by Pitch, and hits credited to the batters during their plate appearance. This market does not include dropped third strikes, reach on errors, fielder’s choice, and catcher’s interference.
Player Total Bases
Total bases for a player are recorded through hits. They do not include walks, Hit by Pitch, bases advanced as a runner, reach on errors, or fielder’s choice.
Wager will be graded based on the number of the selected specific outcome that a player records in the designated period.
Outcome of First Pitch (Listed Pitcher)
Settled based on the result of the first pitch thrown by the listed pitcher. BetMGM will cancel wagers if there is a change to the listed pitcher before the first thrown pitch. For settlement purposes, batted balls that result in the plate appearance ending (ex: hits/outs) do not count as strikes. If a pitcher or batter violation results in an automatic ball or strike, then the market is settled based on the outcome of the violation. Hit by pitch and pitch outs are settled as a “Ball.” The “In-Play” selection includes any type of hit (single, double, etc.) and any batted ball that results in an out(s) being recorded.
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 cancelled 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
Home Run Derby Markets
Calculation of total home runs for Home Run Derby wagers includes home runs achieved during swing-offs.

Baseball Same Game Parlay Rules
Baseball Same Game Parlay rules are the same as Baseball rules stated above, with the following exceptions:
Bet Settlement (For Same Game Parlay):
All Baseball Same Game Parlay selections must win (no ties, draws or pushes) for a bet to be deemed a winner. A selection that does not win, unless explicitly specified in the Baseball Same Game Parlay Rules, will be settled as a loser. If one or more selections in any bet are resulted as cancelled for any reason (such as a selected player not participating in the match), the entire bet will be resulted as cancelled.
For instance, selections on a team to win a match where it is a draw after extra innings (or normal time if no extra innings are to be played), even where the draw or tie may not have been offered through Same Game Parlay, will be settled as losers. This will not be relevant to MLB matches as extra innings are played until a winner is decided, but may be applicable to other baseball leagues or competitions as per their individual competition rules.
Extra Innings (For Same Game Parlay):
All baseball matches are settled on the official declared result including any extra innings. All team and player statistics accrued during extra innings are included for the purposes of bet settlement.
Listed / Designated / Named Pitchers (For Same Game Parlay)
Baseball Same Game Parlay selections are not reliant on whether the pitchers who are listed/designated/named prior to the match are active. If either or both originally announced starting pitchers in a game are scratched or replaced by other pitchers prior to the match commencing and after any bets have been placed, those bets will stand. If pitchers may have been listed in, or relative to, the display of any selections, it will be treated as indicative only and will not affect or prevent the application of this rule.
Player Specific Markets (For Same Game Parlay):
If a player does not participate in a match, selections specific to that player (and therefore the entire bet) will be cancelled. This rule is applied as follows:
Selections on hitting / batting markets will be active if the player in question gets at least one plate appearance. If the player does not appear at the plate, these selections will be treated as cancelled.
Selections on base stealing markets will be active if the player in question enters the game at any point. This includes making a plate appearance but also playing as a fielder, defensive substitute, pinch-runner, and so on. If the player does not enter the game in any such capacity at any point, these selections will be treated as cancelled.
Selections on pitching markets will be active if the player in question throws at least one pitch in the game. If the player does not do so, these selections will be treated as cancelled.
Player selections will be considered active or cancelled regardless of whether a selection may reference a specific period of a match. For instance, a selection on a certain player to get 1+ hits in the first 5 innings of a match would be active (and therefore settled as a loser) if that player only entered the game as a substitute after the 5th inning, and made his plate appearance(s) from that point. However, if that player was injured shortly before the game commenced, was withdrawn from the starting lineup (or bench) and thus did not make any plate appearances, the selection and therefore bet would be cancelled.
Race to X Runs (For Same Game Parlay):
“Race to X” selections where neither team reaches the selected score will be settled as losers, regardless of whether a “neither team to reach X” selection was available as an alternate selection or not.
Postponed Matches (For Same Game Parlay):
If a baseball match does not commence on the scheduled calendar day of the officially listed start time, all bets on the match will be cancelled. Where a match is suspended after it has commenced and subsequently resumed within 36 hours (inclusive) of the originally scheduled start time, all bets will stand.
All bets placed on matches that are postponed and subsequently resumed more than 36 hours past the originally scheduled start time, or not resumed at all, will be settled in accordance with the Reduced-Innings Matches section.
This section on postponed matches does not apply to playoff or postseason tournament matches. In the case of a suspended playoff or postseason tournament game, all bets will stand through any case of suspension until the game is officially completed as per the relevant governing body.
All Baseball Same Game Parlay selections placed on baseball matches that are shortened after the match has commenced (for instance, fewer innings are played due to bad weather), the selections will be settled as follows:
Same Game Parlays will be cancelled if they include at least one player-specific selection involving a player who has not yet entered the field as an active player. The rules outlined below are all applied subject to, and subsequent to, the application of this rule.
If every selection within a Same Game Parlay is already definitively a winner prior to the match being shortened where the fact of reduced innings has no impact on the outcome of each selection, the wager in its entirety will be treated as a winner. For example, a 2-leg Same Game Parlay containing an Over Total Runs selection and a Player to Hit a Home Run selection, in a game where the required runs total had been reached and the player did hit a home run prior to the match being shortened, will be treated as a winner. The same would not apply to an Under Total Runs selection where the match is shortened while the score is still under the required total, as the reduced innings would impact that outcome.
If a single selection of a Same Game Parlay has been unconditionally determined to be a loser regardless of the fact of reduced innings, and the match is then shortened, then the Same Game Parlay will be treated as a loser in its entirety. For example, a Same Game Parlay including a First Player to Score selection, in a game where a different player scored first and the match was subsequently shortened, will be treated as a loser. In this case, the bet had already lost, and the outcome could not be affected in any way even if the game was not shortened.
If there are no losing selections within a Same Game Parlay and at least one cancelled selection at the time the match is shortened after commencement, then the Same Game Parlay will be treated as cancelled. This rule applies where one or more selections are still undecided after the reduced number of innings have been completed and may have won or lost if the game had been completed as scheduled. For example, a Same Game Parlay including an Over Total Runs selection, in a game shortened while the total runs are still below the required amount, will be treated as cancelled. In this case, the total points selection was still undecided and may have won or lost but for the reduced innings, so the bet will be cancelled.
If the applicable league or governing body attributes a win/loss result to the match with reduced innings, then selections on the Match Winner, Moneyline or Head-to-Head markets will be settled according to the official league result regardless of whether the match was concluded with reduced innings. If the match is not designated with an official win/loss result by the relevant league or governing body, then selections on the Match Winner, Moneyline and Head-to-Head markets will be cancelled.
The rules presented in this section for baseball matches with reduced innings do not apply to matches that, prior to its commencement, are originally scheduled to be played for fewer than 9 innings (for example, MLB double-headers that are scheduled as 7-inning matches).
Matches concluded after 8.5 innings because the home team is ahead after 8.5 innings (or, in the case of a game scheduled to be 7 innings, after 6.5 innings) are not treated as shortened matches.
Cancelled Matches (For Same Game Parlay):
If a match is abandoned prior to commencement, it falls within the 36-hour rule for postponed matches as described in the Postponed Matches section. If a match is abandoned after commencing but before its full scheduled innings, it will be settled under Reduced-Inning Matches rules.
Venue Changes (For Same Game Parlay):
If the venue of a match is changed from the one originally scheduled, bets will stand if the original home and away teams remain designated as such. If the venue is changed and the home and away team designations are reversed, bets placed under the original home/away listing will be cancelled.
Same Game Parlay Plus:
The general SGP and SGP+ settlement rules outlined above apply to all SGP wagers on Baseball events within the SGP+ wager. Wagers within the SGP+ on other sports follow that sport’s house rules.
If any selection (either SGP or Single wager) within an SGP+ is settled as a loss, then the entire SGP+ is settled as a loss.
If any leg in a SGP is void or cancelled, then the entire SGP is void. If all other SGP or Single wagers within a SGP+ are winners, the SGP+ will be paid out at a re-calculated price using the remaining legs.
Playoff Series Props:
Wager on which team will advance to the next round. Should no series take place, bets will be cancelled.
Series Correct Score
Wager on the exact score of games within the series. Should the series be shortened from its original length, then bets would be cancelled.
Wager on how many games will take place in the series.
