Major League Baseball games are official after 5 innings of play, or 4.5 innings if the home team is leading. If a game is subsequently called or suspended, the winner is determined by the score after the last full inning, unless the home team ties the score or takes the lead in the bottom half of the inning in which the game was suspended. Then the winner will be determined by the score at the time the game is called. (This rule holds for betting purposes even if the game is suspended and /or completed on a different day than the event began).

  • The maximum bet that can be placed on a baseball game to be competed the next day is $500.  The overnight bet limits will be in effect until at least 10 a.m. Eastern time on the day of the games.
  • When wagering on total runs or run lines, the game must go the regulation 9 innings, or 8.5 innings if the home team is leading, otherwise it will constitute a “No Action” wager, and all money will be credited accordingly.
  • Baseball wagers are accepted as “Listed”.  In the event of a pitching change prior to the game, all wagers on the game with said listed pitchers are considered “No Action” and will be refunded.
  • Starting Pitchers must throw at least one pitch for wager to be deemed “Action”.

Any and all baseball series wagers must have all 3 games played by the end of a specified date for the wager to have action. If all 3 games are not played by that specified date then all wagers are NO ACTION, regardless if one team has 2 wins. All 3 games must be official by Las Vegas Gaming Standards.

NOTE: Each team’s starting pitcher is defined for betting purposes as the pitcher that throws the first pitch.

NOTE: If we provide a baseball series price for a series that has 4 games, for grading purposes, the wager is based on the initial 3 games.

  • All baseball props must go the full 9 (8, if the Home Team is Winning) innings unless otherwise stated. They also must start the listed pitchers.
