How Many Innings Are Needed to Have a Complete MLB Game After a Rain Delay?

If either team is leading after five innings and the game is called for rain, the game is considered a complete regulation game. If the game is tied at five innings and the game is called for rain, the game is suspended to be completed at a later time. Games that have not made it to 4 1/2 innings before rain ends play are replayed in entirety at a later time.
