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:
“I have not earned what I have already enjoyed.”
—Henry David Thoreau (1817–1862)
“beauty is like piety—you cannot run and read it; tranquility and constancy, with, now-a-days, an easy chair, are needed.”
—Herman Melville (1819–1891)
“That’s one thing I like about Hollywood. The writer is there revealed in his ultimate corruption. He asks no praise, because his praise comes to him in the form of a salary check. In Hollywood the average writer is not young, not honest, not brave, and a bit overdressed. But he is darn good company, which book writers as a rule are not. He is better than what he writes. Most book writers are not as good.”
—Raymond Chandler (1888–1959)
