Ed Walsh: Lowest ERA in MLB History

Ed Walsh: Low Average

In the professional baseball record books, the name Ed Walsh won’t be the first to jump out when people discuss the best starting pitchers of all time. However, what the man many called “Big Ed” does have in his favor, even to this day, is the lowest career ERA in baseball history. Ed Walsh’s 14-year career remains one of the most remarkable in the sport when it comes to the earned run average statistic.

A Standout Rookie in Chicago

Walsh started off slowly for the Chicago White Sox in the 1904 regular season. In his rookie year, Walsh went 6-3 with a 2.30 ERA, recording 6 complete games, 1 shutout, and 1 save. Walsh picked things up considerably the following year, going 8-3 in 1905 with a 2.17 ERA, recording 9 complete games and 1 shutout.

1906: A World Series Champion

The 1906 season ended up being the crowning achievement of Walsh’s young career, as he went 17-13 with 171 strikeouts and a sparkling 1.88 ERA, recording 24 complete games, 10 shutouts, and 2 saves. Ed Walsh helped the White Sox win the 1906 World Series by defeating their Windy City rivals, the Chicago Cubs. In that Fall Classic, Walsh went 2-0 with 17 strikeouts and a microscopic 0.60 ERA, recording 1 complete game and 1 shutout. In Game 3 on October 11, Walsh pitched a complete game, giving up only 2 hits and 1 walk while recording an impressive 12 strikeouts. In Game 5 on October 13, Walsh pitched 5 innings and gave up 5 hits, 5 walks, 1 earned run, and 6 total runs, posting that 0.60 series ERA.

The Dominant Prime Years

While he would never get another chance at a World Series championship, Walsh remained remarkably steady in the years that followed, turning in some of the best pitching seasons of the dead-ball era.

1907 to 1909

Walsh went 24-18 in 1907 with 206 strikeouts and led the American League with a stingy 1.60 ERA, recording 37 complete games, 5 shutouts, and 4 saves. In 1908, Walsh was at his most dominant, leading the AL with 40 wins as he went 40-15 with 269 strikeouts and a minuscule 1.42 ERA, recording 42 complete games, 11 shutouts, and 6 saves. In 1909, Walsh went 15-11 with 127 strikeouts and a tiny 1.41 ERA, recording 20 complete games, 8 shutouts, and 2 saves.

1910 to 1912

The 1910 season was the only complete year in which Walsh recorded a losing record, going 18-20. However, he was excellent in every other category, posting 258 strikeouts and a league-leading 1.27 ERA, the lowest of his career. He recorded 33 complete games, 7 shutouts, and 5 saves. Walsh bounced back in 1911, going 27-18 with 255 strikeouts and a 2.22 ERA, recording 33 complete games, 5 shutouts, and 4 saves. In 1912, Walsh went 27-17 with 254 strikeouts and a 2.15 ERA, recording 32 complete games, 6 shutouts, and 10 saves.

Decline and Final Seasons

1913 was the first year in which the decline of Ed Walsh as a pitcher became evident. He went 8-3 with a 2.58 ERA, recording 7 complete games, 1 shutout, and 1 save. In 1914, he went 2-3 with a 2.82 ERA, 3 complete games, and 1 shutout. In 1915, Walsh went 3-0 with a tiny 1.33 ERA, 3 complete games, and 1 shutout. The last two years of Ed Walsh’s career saw him making brief appearances for the White Sox in 1916 and for the National League’s Boston Braves in 1917. Walsh attempted a comeback with the Braves in 1917, but he never got going, and he was released after losing just 1 game.

Hall of Fame Legacy and the ERA Record

In 1946, the National Baseball Hall of Fame in Cooperstown, New York, opened its doors to Ed Walsh, inducting him among the game’s greats. It is difficult to fully evaluate Walsh’s official statistics, since most of his career came before earned run average was an official statistic; the ERA wasn’t officially adopted by the National League and American League until 1912. Nonetheless, Ed Walsh still holds the lowest career ERA in baseball history, an almost untouchable mark of 1.82.

The Origins of the ERA Statistic

One reason the ERA statistic came into being was that relief pitching became a real option for teams to use, which made a pitcher’s win-loss record a less reliable measure of his individual performance. Credit for inventing the ERA statistic belongs to Henry Chadwick, a sportswriter and baseball historian. Earned Run Average is calculated by dividing the number of earned runs a pitcher allows by the number of innings he pitches, then multiplying that figure by nine. In Ed Walsh’s era, it was routine for pitchers to throw complete games, which was part of what inspired Chadwick to create the statistic in the first place.

What Makes a Good ERA Today

In today’s game, ERA remains one of the most important statistics for evaluating a pitcher. A common benchmark for judging whether a pitcher’s ERA is good or bad is a range running from 0.00 to 4.00, with lower numbers reflecting better performance. Ed Walsh’s lowest career ERA in baseball history sits so far below that scale that it remains in a class of its own more than a century later.
