In order for a game to be officially settled (i.e. for moneyline and over/under wagers to pay) the game must go at least nine full innings or 8.5 innings if the home team is ahead. This rule is in place because baseball games are often shortened or suspended due to weather conditions. If a game is halted and not scheduled to resume from the point where it was paused, all bets will be void, except for those that have already been determined, such as a first inning over/under.
Player Props – In order for any MLB player prop to have action, the player must throw at least one pitch or record at least one plate appearance in the designated game. This rule applies to both live and pre-game betting.
Playoff Game Rule – In order for bets on playoff or postseason tournament games to have action, the event must reach its full conclusion as determined by the league’s governing body. Playoff and postseason tournament games that are halted are settled as dead heats, unless the bet type specifies that a winner will be declared by a specific method.
NBA players are not allowed to place bets while they are inside team facilities or on the road with their teams, but they can make wagers elsewhere as long as the sportsbooks are licensed in Virginia. However, players are required to sign a statement acknowledging gambling rules as part of their CBA contracts.
