SBR Mailbag: MLB Betting Rules on Suspended Games

A Sportsbook Review reader has submitted a question concerning the grading of an MLB wager placed on last night's Kansas City Royals vs. Chicago White sox game.

The game was called off in the 8th inning due to rain, but the reader noted that one sports betting website graded his wager as no-action (returning his bet) and another settled his bet as a loss.

At the time of play suspension, the game was tied 2-2.

So, which sportsbook was correct?

The answer depends on the rule book. Most commonly, North American facing betting sites will adhere to Vegas rules and have printed such in their terms and conditions. That rule is often written as follows:

Run-lines and totals: "A Major League Baseball game is official after 8.5 innings if the home team is winning, or 9 innings if the visitor is ahead. If the game does not go 9 innings (8.5 if the home team is in front), all totals and run-line bets are voided."

Moneyline bets: "An MLB become is considered official for moneyline bets after 4.5 innings if the home team is winning, or 5 innings if the visitor is ahead."

European bookmakers often have their own ruling on MLB betting, especially because most offer in-play betting which has its own can of worms. Some bookmakers treat all wagers as action regardless of pitcher changes for example, and others adhere to the North American facing standard followed by Vegas.

It is important to know how a wager will be treated before betting in the event of weather, injury, or venue disruption. It might save you money in the long-run.
