The American League (AL) is one of the two leagues of Major League Baseball. The team with the highest winning percentage in the league won the pennant and faced the National League pennant winner in the World Series (in 1903 and 1905-1968).
In 1969, the league split into East and West divisions, and the two division winners played in the American League Championship Series to determine the league champion who would then face the National League champion in the World Series.
