San Francisco Giants All-Time ERA Leaders
The San Francisco Giants have been in San Francisco since 1958 and before that were the New York Giants from 1885 until 1957, and before that were the New York Gothams in 1883 and 1884. The franchise has five championships, all with the New York version of the team, but the San Francisco Giants have been competitive for many years of their existence. They have also had a knack for developing pitchers. What follows is a short list of the Giants’ all-time leaders in earned run average (ERA) to date:
Christy Mathewson (2.12)—Hall of Famer Christy Mathewson was one of the game’s greatest pitchers of all-time. Mathewson pitched for the New York Giants from 1900 to 1916, and he ranks first in team history with a 2.12 ERA. Mathewson had a career best 1.14 ERA in 1909, but his best season was probably 1908. That year, Mathewson had a career high in wins (37-11) with a 1.43 ERA and 259 strikeouts. He also had 34 complete games and 11 shutouts, and the wins, ERA, K’s, complete games and shutouts all led the National League that season.
Slim Sallee (2.26)—Slim Sallee pitched for the New York Giants from 1916 to 1918 and again in 1920 and 1921. He ranks second in franchise history in earned run average with a 2.26 mark. Sallee had a career best 2.06 ERA with Cincinnati, and his best season for the Giants was 1917. That year, he went 18-7 with a 2.17 ERA, 4 saves and 54 strikeouts.
Joe McGinnity (2.38)—Joe McGinnity pitched for the Giants from 1902 to 1908, and he ranks third in the team’s history with a 2.38 ERA. McGinnity had his best season in 1904, when he had career best numbers in wins (35-8) and ERA (1.61) with 144 strikeouts. The wins and ERA both led the National League that season.
Jeff Tesreau (2.43)—Jeff Tesreau pitched for the New York Giants his entire career, from 1912 to 1918, and he ranks fourth in Giants’ history with a 2.43 earn run average. Tesreau had a career best 1.96 ERA (which led the NL) in 1912, but his best overall season was probably 1914. That year, Tesreau went 26-10 (career high in wins) with a 2.37 ERA and 189 strikeouts (also a career best).
Red Ames (2.45)—Red Ames began his career with the Giants and pitched for them from 1903 to 1913. He ranks fifth in franchise history with a 2.45 ERA, and he had a career best 1.29 mark in 1903, but that was only in two games. Ames’ best overall season was arguably 1905. That year, he had a 2.74 ERA to go along with career highs in wins (22-8) and strikeouts (198).
