A standard World Series game in Major League Baseball is nine innings, but it can go longer if the score is tied.

Quick Scoop

  • Each World Series game follows normal MLB rules: 9 regulation innings.
  • If the game is tied after 9, it goes to extra innings until one team leads at the end of a full inning, with no set maximum.
  • The series itself is best-of-seven games, but that does not change the number of innings in an individual game.

So if you are just asking “how many innings in World Series?”, the expected answer is 9 innings per game, with extras possible in a tie.
