The 1913 World Series was the championship series in Major League Baseball for the 1913 season. The tenth edition of the World Series, it matched the American League (AL) champion Philadelphia Athletics against the National League (NL) New York Giants. The Athletics won the Series four games to one. The A's pitching gave the edge to a closer-than-it-looked Series in 1913. Christy Mathewson lost his Series swan song in the final game to an old college rival and eventual fellow Baseball Hall of Fame member, Eddie Plank.
