In baseball statistics, Earned Run Average, or ERA, is one of the most well-known pitching statistics and represents the average number of earned runs a pitcher will give up per nine-inning game. It is determined by dividing the total number of earned runs allowed by the number of innings pitched and multiplying by nine.
The formula for calculating ERA is: ERA = (Earned Runs Allowed x 9) / Innings Pitched. Earned Runs Allowed are runs given up by the pitcher that are not due to fielding errors or passed balls. Innings Pitched measures the number of innings thrown by the pitcher. The number 9 is used because baseball games last 9 innings.

We then divide this by the innings pitched which is 27 divided by 5 = 5.40. In case you’re wondering what the good, bad and the ugly are ERA-wise in the ...
