The World Series is a best-of-seven championship, so it can last anywhere from 4 to 7 games depending on when one team reaches four wins.

Basic format

  • The World Series uses a best-of-seven format: the first team to win four games becomes champion.
  • Because of this, the series can end in 4, 5, 6, or 7 games in total.

Minimum and maximum games

  • Minimum: 4 games, if one team wins four straight (a sweep).
  • Maximum: 7 games, if the teams split the first six and a deciding Game 7 is needed.

Quick historical note

  • Earlier in history, the World Series was sometimes a best-of-nine, but it has been a best-of-seven for nearly all seasons since the early 1920s.
