In baseball statistics, earned run average (ERA) is the mean of earned runs given up by a pitcher per nine innings pitched. It is determined by dividing the number of earned runs allowed by the number of innings pitched and multiplying by nine. Runs resulting from defensive errors (including pitchers' defensive errors) are recorded as unearned runs and are not used to determine ERA.

Famous quotes containing the words earned, run and/or average:
““What have I earned for all that work,” I said,
“For all that I have done at my own charge?
The daily spite of this unmannerly town,
Where who has served the most is most defamed,
The reputation of his lifetime lost
Between the night and morning....””
—William Butler Yeats (1865–1939)
“Lord, thy most pointed pleasure take
And stab my spirit broad awake;
Or, Lord, if too obdurate I,
Choose thou, before that spirit die,
A piercing pain, a killing sin,
And to my dead heart run them in!”
—Robert Louis Stevenson (1850–1894)
“The average Kentuckian may appear a bit confused in his knowledge of history, but he is firmly certain about current politics. Kentucky cannot claim first place in political importance, but it tops the list in its keen enjoyment of politics for its own sake. It takes the average Kentuckian only a matter of moments to dispose of the weather and personal helath, but he never tires of a political discussion.”
—For the State of Kentucky, U.S. public relief program (1935-1943)
