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.

““What have I earned for all that work,” I said,
“For all that I have done at my own charge?

Where who has served the most is most defamed,
The reputation of his lifetime lost
Between the night and morning....””

“Power, I said. Power to walk into the gold vaults of the nations, into the secrets of kings, into the holy of holies. Power to make multitudes run squealing in terror at the touch of my little invisible finger. Even the moon’s frightened of me. Frightened to death. The whole world’s frightened to death.”
—R.C. Sherriff (1896–1975)
“The average American is a good sport, plays by the rules. But this war is no game. And no secret agent is a hero or a good sport—that is, no living agent.”
