 This rule was put into place as a result of Game 5 of the 2008 World Series, which was the first postseason game in history to be suspended and resumed from the point of suspension.Prior to the 2009 postseason, a playoff game had to have at least five innings completed in order to be suspendable; a playoff game stopped prior to that point had to be started over.In nearly all cases, the "official game" status is used to determine whether a rain check will be honored for fans holding tickets.
