# How to Calculate ERA in Baseball

How to Calculate ERA in Baseball. A pitcher’s ERA, or earned run average, measures

how many earned runs they allowed during a game. Learn how to calculate ERA, and see if your

favorite pitcher is really as strong as he seems. You will need Calculator and basic understanding

of baseball. Step 1. Determine the total number of innings pitched. For partially played innings, add in one-third

of an inning for each out recorded. For example, if a pitcher threw 6 full innings,

then recorded one out in the seventh, he threw 6 1/3 innings. Step 2. Calculate the total number of earned runs

allowed. For innings where no errors occurred, this

will be the total number of runs. If errors did occur, add in only the runs

that would have scored had there not been an error. Remember to include earned runs that might

come after the pitcher leaves the game. If a hitter gets on base against a pitcher,

that runner is his responsibility, even if the pitcher has been taken out of the game. Step 3. Divide the total number of earned runs by

the total number of innings pitched. Step 4. Multiply by 9, and round this number to 2

decimal places to find the pitcher’s ERA. For Major League ball players, an ERA of 4

is about average, and an ERA of 2 or less is excellent. Did you know Ed Walsh, who played with the

Chicago White Sox from 1904 to 1916, has the lowest career ERA in Major League baseball

at 1.82. But the statistic is unofficial, since the

American League didn’t accept ERA as a statistic until 1913.

Baseball very stupid game over the world

This video is shit

Ah lower is better. Why didn't they just say that.

Thank you

David Ross has a 0 era

I’m just watching this for algebra😂

MLB notates ⅓ of an inning as .1, and ⅔ of an inning as .2. This incorrect notation is lowering the overall ERA of the pitchers. I'm glad you did it the correct way in this video.
