# Scoreless innings streak

In baseball, a scoreless innings streak is the number of consecutive official innings in which a pitcher appears and allows no runs. Such a streak will end when the pitcher allows a run, earned or unearned. Since 1998, the Official Baseball Rules state that a pitcher does not get credit for any outs recorded during an inning in which he is charged with an earned or unearned run.
Orel Hershiser holds the Major League Baseball record of 59 consecutive scoreless innings which began on August 20, 1988 and ended on September 28, 1989, breaking Don Drysdale's record of 58 consecutive scoreless innings in 1968, the "Year of the Pitcher." Drysdale and Hershiser are the only pitchers to record a 50-inning streak in the live ball era; Walter Johnson and Jack Coombs both also recorded 50 consecutive scoreless innings, with Johnson's 55-inning streak being the MLB record for 55 years and still being the American League record and Coombs' 53-inning streak being the record before that.
Mariano Rivera holds the postseason record for consecutive scoreless innings, with 33+1⁄3. The second-longest postseason streak was pitched by Whitey Ford, whose 33 consecutive scoreless innings is a World Series record; Ford broke Babe Ruth's 43-year-old record of 29 scoreless innings. Christy Mathewson holds the National League record with 28 consecutive scoreless innings in the postseason.
