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.

World Series

The World Series is the championship series of Major League Baseball in the United States and Canada, the culmination of the sport's postseason each October. It is played between the pennant winner of the American League and the pennant winner of the National League. The Series winner is determined through a best-of-seven playoff (except in 1903, 1919, 1920 and 1921 when the winner was determined through a best-of-nine playoff) and is awarded the World Series Trophy, as well as World Series rings.
