Earned
Run
Average
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 multiplying the number of earned runs allowed by nine and dividing by the number of innings pitched.

They almost have it. ERA ie.. (earned run average) is based on outs pitched in a game, there are 27 outs in a 9 inning game,that is why you may see a high (ERA) on a pitcher if he gives up a lot of runs before he gets 3 outs to end the inning.

Earned Run Average. You compute it as follows:
(Earned Runs * 9) / Innings pitched.
For example, if a pitcher gives up 3 earned runs in 5 2/3 innings, his ERA would be 4.77

The National League first kept official earned run average statistics in 1912 (the statistic was called Heydler's Statistic for a while, after then-NL secretary John Heydler), with the American League following suit afterward.

earned run average. lets say a pitcher pitches a complete 9 inning game, and he gives up 1 earned run. then his era is 1.00
its simple when you do multiples of 3. but for the most part everybody else is right. nobody had in mathematical terms though. i just wanted to give you an example.

I a pitcher inherits runners in scoring position they won't count towards the new pitcher's ERA. Say I come out of the bull pen with a runner on third base and 1 out. I give up a sac fly and the runner scores. The earned run will still go towards the pitcher who allowed the runner to third, unless he reached third on an error. Now, who wants to explaind WHIP, just kidding.
