19. Baseball rules

Smarkets general betting rules (1-11) will apply unless superseded by the Terms and Conditions or sports specific betting rules.

19.1   General 

19.1.1   Bets will be settled as their outcomes become determined. Later decisions to void markets will not affect earlier settled markets if the outcomes of which are unaffected.

19.1.2   Matches must begin within 36 hours of the initially scheduled start time, or be voided. If a match begins but is later abandoned or postponed an official result must be declared within 36 hours for outstanding bets that have not yet been unconditionally determined to be valid.

19.1.3   Extra innings will be included unless stated otherwise.

19.1.4  At least nine innings (or 8.5 innings if the home team is ahead) must be completed for bets on ‘Total runs’, ‘Run line’ or Total 'Hits' markets to be valid. This applies except in cases where the match was always scheduled to be played with less innings, (for example scheduled 7 innings double header matches during the 2020 MLB season), where the number of innings is specified in the market name or where the outcome of the market has already been determined.

19.1.5   If a match is scheduled to be played with less than 9 innings, at least the stated number of innings (or half an innings less if the home team is ahead) must be completed for bets on 'Total runs' or 'Run line' markets to be valid unless the outcome of the market has already been determined.

19.1.6   If a game is abandoned all bets placed on winner markets will be voided:

  • If the game is not replayed within 36 hours of the original start time
  • Or unless five innings have been played (or 4.5 innings if the home team is ahead).

An official result must still be declared in either of the above cases in order for bets on the winner market to be settled.

19.1.7   Unless otherwise specified, such as for MLB below, all bets will stand regardless of whether a listed starting pitcher starts the first innings for their respective team or not.

19.1.8 Money Line & Total Runs: At least 4.5 innings must be completed for the Money Line to be valid, for the Total Runs at least 9 Innings (or 8.5 innings if the home team is ahead) must be completed to be valid unless the outcome has already been determined. If either of these conditions are not met the market would be void.

19.1.9 Run Line and Total Runs: At least nine innings (or 8.5 innings if the home team is ahead) must be completed for bets to be valid unless the mercy rule is used in which case this market would settle on the score at that time.

19.1.10 Most/ Total Hits: At least nine innings (or 8.5 innings if the home team is ahead) must be completed for bets to be valid

19.1.11 Race to Runs: The first team to reach the stated number of runs will be settled as the winner. At least nine innings (or 8.5 innings if the home team is ahead) must be completed for bets to be valid unless the market has already been determined

19.1.16 Winning Margin: This market will be settled based on the final result of the match including any extra innings. Should the match be suspended and cancelled this market would be void should 9 innings (or 8.5 if the home team is ahead) not have been completed or scores are tied.

19.1.17 Extra Innings: The 9th inning must be complete for bets to be valid. If the score is tied after 9 innings then this market will be settled as Yes even if the extra innings are not played due to the game being postponed.

19.1.18 Highest Scoring Period: At least 9 innings (or 8.5 if the home team is ahead) must be completed for this market to be settled.

19.1.19 Correct Score - this market will be settled based on the final result of the match including any extra innings played. If at least nine innings (or 8.5 innings if the home team is ahead) are not completed or the game is suspended while scores are tied this market will be void.

If both teams have the same highest score then Tie will be settled as the winner regardless of the umber of times the highest score is reached. 

19.1.25 Team to Score First Home Run of the Game: This market will be settled on the first home run scored. This market would be void if neither team make a home run.

19.1.26 Team Total Odd/Even: In the event of zero runs being scored in this match by the named team, the result will be settled as Even.
