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 champner of the American League and the pennant champner of the National League. The Series champner is determined through a best-of-seven playoff (except in 1903, 1919, 1920 and 1921 when the champner was determined through a best-of-nine playoff) and is awarded the World Series Trophy, as well as World Series rings.
