Best Answer

A pitcher's era (earned run average) is calculated as follows: 1. Number of Earned Runs 2. Times 9 3. Divided by number of innings pitched So, if a pitcher gives up 3 earned runs in 5 innings then we first multiply 3 times 9 = 27. Then we take 27 and divide it by 5 (for innings pitched) to get an era of 5.4. Also, an earned run is a run that scores without the defense creating any errors.
