# List of Major League Baseball annual ERA leaders

Ed Walsh's career earned run average (ERA) of 1.82 is the lowest in the history of Major League Baseball.[1]

In baseball, earned run average (ERA) is a statistic used to evaluate pitchers, calculated as the mean of earned runs given up by a pitcher per nine innings pitched.[a] A pitcher is assessed an earned run for each run scored by a baserunner who reached base while batting against that pitcher, whether by hit, base on balls or "walk", or being hit by a pitched ball;[2] an earned run can be charged after the pitcher is relieved if he allows the runner before leaving the game.[3] Runs scored by players who reach base on errors, passed balls, or catcher interference under special circumstances are treated as unearned runs, and do not count towards the pitcher's ERA.[3]

Major League Baseball recognizes the player in each league[b] with the lowest earned run average each season.[c] The first ERA champion in the National League was George Bradley; in the National League's inaugural 1876 season, Bradley posted a 1.23 ERA for the St. Louis Brown Stockings, allowing 78 earned runs in 573 innings pitched.[4] The American League was established in 1901, and Hall of Fame pitcher Cy Young led that league with a 1.62 ERA for the Boston Americans during the 1901 season.[5]

Over the course of his 17-year major league career, Lefty Grove led the American League in ERA nine times, with a career single-season low of 2.06 for the 1931 Philadelphia Athletics.[6] Roger Clemens has won the second-most ERA titles, capturing six in the American League and one in the National League.[7] Sandy Koufax led the National League in ERA for five consecutive seasons (1962–1966); Koufax' five awards are the most won consecutively by any player and are tied for the most awards by a player in the National League with Christy Mathewson and Clayton Kershaw.[8][9][10] In the American League, Walter Johnson also won five ERA titles,[11] and Pedro Martínez has won a total of five (four American League and one National League) with two different teams.[12]

The most recent ERA champions are Blake Snell in the American League and Jacob deGrom in the National League.

The lowest single-season ERA in league history was posted by Tim Keefe, whose 0.86 ERA in 105 innings pitched for the National League's Troy Trojans in 1880 led his closest competitor by .52 runs.[13] In the American League, Dutch Leonard's 0.96 ERA is a single-season record.[14] Keefe and Leonard are the only two pitchers ever to allow less than one run per nine innings pitched in a single season. The widest margin of victory for an ERA champion is 1.96 runs, achieved when Martínez' 1.74 ERA led Clemens' 3.70 in the American League during the 2000 season. The largest margin of victory in the National League is 1.26 runs—Dazzy Vance's 2.61 ERA over Carl Hubbell's 3.87 in 1930. The smallest margin of victory for an ERA champion is .009 runs. Although the statistic is traditionally recorded to two decimal places by most sources,[15][16][17] the 1988 American League title was decided by a margin of less than one hundredth of a run when Allan Anderson's ERA of 2.446 (55 earned runs in ​202 13 innings)[18] bested Teddy Higuera's 2.455 mark (62 earned runs in ​227 13 innings).[19] Other contests decided by one hundredth or less include Luis Tiant's 1.91 ERA ahead of Gaylord Perry's 1.92 in 1972[20][21] and Mark Fidrych (2.34) over Vida Blue (2.35) in 1976.[22][23]

## National League

Tommy Bond won the triple crown in 1877, leading the National League in wins, strikeouts, and ERA.[24]
Christy Mathewson's career ERA of 2.13 is eighth on the all-time list; he led the National League in ERA five times during his career.
Grover Cleveland Alexander won the National League ERA title four times with two different teams (the Philadelphia Phillies and the Chicago Cubs).
Mordecai "Three-Finger" Brown led the league in ERA in 1906 and finished second three times.
Amos Rusie led the National League in ERA in 1894 and 1897, and finished second to Ted Breitenstein in 1893.
Sandy Koufax' five consecutive seasons leading the National League in ERA is a Major League Baseball record.
Jake Peavy's 2007 ERA of 2.54 led all National League pitchers.[25]
Johan Santana won the ERA title in his first National League season after eight years with the Minnesota Twins.
Chris Carpenter had the lowest ERA in the National League in 2009.
Clayton Kershaw is the first pitcher in history to lead MLB in ERA for 4 consecutive years (2011–2014).

## American League

Addie Joss led the American League in ERA in 1904 and 1908.
In addition to leading the American League in ERA five times in his career and winning three triple crowns,[169] Walter Johnson was one of the five charter members of the Baseball Hall of Fame.
"Smoky" Joe Wood won 15 games in 1915 when he won the ERA title; he is one of thirteen pitchers who have won 30 games in a single season since 1900.[170]
Babe Ruth led the league in ERA in 1916; he began his Major League Baseball career as a pitcher with the Boston Red Sox before converting to the outfield.[171]
Roger Clemens' seven ERA championships are the second-most by any player in Major League Baseball history, behind Lefty Grove's nine.
Pedro Martínez won five ERA titles across both leagues; his 2000 margin of victory over Clemens for the ERA title is the largest in Major League Baseball history.
John Lackey's 3.01 ERA in 2007 led the American League.
Cliff Lee won the Cy Young Award in 2008[172] in addition to the ERA title.
Zack Greinke, pitching for the Kansas City Royals, became the second consecutive pitcher to win the Cy Young Award and lead the American League in ERA in the same season.[172]

### Notes

• a While Baseball-Reference.com lists both Scarborough and Hall of Famer Bob Lemon with an ERA of 2.82 in 1948, Scarborough's average is lower (2.817) than Lemon's (2.820) if extended to three decimal places.
• b c While Baseball-Reference lists both Anderson and Higuera with an ERA of 2.45 in 1988, Anderson's average is lower (2.446) than Higuera's (2.455) if extended to three decimal places.
• d Until 1981, the rules stated that the number of innings pitched should be rounded to the nearest whole inning. This explains why McCatty was, at the time, awarded the 1981 ERA title although his ERA appears to be slightly higher than that of Stewart.[291]

## Other major leagues

Eddie Plank (pictured) was the runner-up in ERA to Earl Moseley in the Federal League's last season of play.
