Baker, who led the American League in home runs in 1911, earned the nickname "Home Run" during the 1911 World Series in which he hit a go-ahead home run off Rube Marquard in game two and a ninth-inning game-tying home run off Christy Mathewson in game three. His home run crown would be the first of four consecutive seasons leading the American League in home runs. He hit 11 HR in 1911, 10 HR in 1912, 12 HR in 1913, and 9 HR in 1914. Two of those seasons, he also led the American League in runs batted in.
