American League pennant winners 1901-68: Meaning (information, definition, explanation, facts)

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).
