World Series

The first two games of the series are played in the home ballpark of the team awarded home-field advantage; the next three are in the other team's ballpark, and the final two, if necessary, are back in the first team's ballpark. That has been the pattern since 1924, with the exception of World War II, when travel restrictions were in place. Until 2003, the team given the home-field advantage was switched every year between the American League and the National League. Starting with the 2003 World Series, the league that wins the mid-season All-Star Game has been awarded home-field advantage.
