Detroit Tigers All-Time ERA Leaders
The Detroit Tigers have been a major league baseball franchise since 1901 and have four world titles to their name. The team has also put some really great talent on the field, especially pitchers. Here is a short list of the Tigers’ all-time leaders in earned run average (ERA) to date:
Harry Coveleski (2.34)—Harry Coveleski pitched for the Tigers from 1914 to 1918 and ranks first in team history with a 2.34 ERA. Coveleski had two seasons in which he posted ERA’s under 1.25 but both were with Philadelphia and both were in just a handful of games. His best overall season was arguably with the Tigers in 1916. That year, Coveleski went 21-11 with a 1.97 ERA and 108 strikeouts.
Ed Killian (2.38)—Ed Killian pitched for the Tigers most of his career, from 1904 to 1910, and he ranks second in franchise history with a 2.38 earned run average. Killian had a career best 1.71 mark in 1909, but his best overall season was 1907. That year, he went 25-13 (career high in wins) with a 1.78 ERA and 96 strikeouts.
Ed Summers (2.42)—Ed Summers pitched his entire (but brief) career with the Tigers, from 1908 to 1912. Summers ranks third in team history with a 2.42 ERA, and his best season was 1908. That year, Summers had career best numbers in wins (24-12) and ERA (1.64) with 5 shutouts and 103 strikeouts.
Bill Donovan (2.49)—Bill Donovan pitched most of his career in Detroit, from 1903 to 1912 and again in 1918. Donovan ranks fourth in Tigers’ history with a 2.49 earned run average, and while he had a few instances of ERA under 2.00, those were in a handful of appearances.
