The 1913 New York Giants season was the franchise's 31st season. It involved the Giants winning the National League pennant for the third consecutive year. Led by manager John McGraw, the Giants dominated the NL and finished 12½ games in front of the second place Philadelphia Phillies. They were beaten by the Philadelphia Athletics in the World Series. Ace pitcher Christy Mathewson went 25–11 and led the NL with a 2.06 ERA. Rube Marquard and Jeff Tesreau also won over 20 games, and the Giants easily allowed the fewest runs of any team in the league. Taken together with the 1911 and 1912 pennant winners, this team is considered one of the greatest of all-time. The roster was basically unchanged from 1912.
