List of Major League Baseball ERA champions
Encyclopedia
In baseball
, earned run average
(ERA) is a statistic
used to evaluate pitcher
s, calculated as the mean
of earned run
s given up by a pitcher per nine innings pitched
. 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
; an earned run can be charged after the pitcher is relieved
if he allows the runner before leaving the game. Runs scored by players who reach base on errors
, passed ball
s, or catcher interference under special circumstances are treated as unearned runs, and do not count towards the pitcher's ERA.
Major League Baseball
recognizes the player in each league with the lowest earned run average each season. 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. 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. 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
. Roger Clemens
has won the second-most ERA titles, capturing six in the American League and one in the National League. 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 in by a player in the National League with Christy Mathewson
. In the American League, Walter Johnson
also won five ERA titles, and Pedro Martínez
has won a total of five (four American League and one National League) with two different teams. Three pitchers have led their leagues in ERA four times: Grover Cleveland Alexander
, Randy Johnson
, and Greg Maddux
; all but Johnson won each of his titles in the National League. The most recent ERA champions are Justin Verlander
in the American League and Clayton Kershaw
in the National League.
The lowest single-season ERA in league history was posted by Tim Keefe
, whose 0.86 ERA for the National League's Troy Trojans in 1880 led his closest competitor by .52 runs. In the American League, Dutch Leonard
's 0.96 ERA is a single-season record. 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 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 innings) bested Teddy Higuera
's 2.455 mark (62 earned runs in innings). Other contests decided by one hundredth or less include Luis Tiant
's 1.91 ERA ahead of Gaylord Perry
's 1.92 in 1972 and Mark Fidrych
(2.34) over Vida Blue
(2.35) in 1976.
