How do you figure out a pitchers ERA?

Answer 1

ERA is based on 9 innings pitched. When you see a pitcher with a 4.94 ERA that means for every 9 innings pitched, he gives up 4.94 earned runs.

Example: A pitcher has pitched 150 innings and given up 60 earned runs.

1) Divide the number of earned runs (60) by the number of innings pitched (150) =0.40.

2) Then take that number (0.4) and multiply it by 9 =3.60.

A pitcher who has pitched 150 innings and given up 60 earned runs has an ERA of 3.60.

Answer 2

Earned Runs Average is computed by the formula: 9 x (Earned Runs Allowed/Innings Pitched).

For example, if a pitcher threw 7 complete innings, allowing 4 earned runs, the formula would be: 9 x (4/7) = 5.14 ERA.

Answer 3

The ERA (Earned Run Average) is calculated by dividing the number of earned runs the pitcher has allowed by his innings pitched, then multiplying that result by 9.

Answer 4

Innings pitched divided by Earned runs times 9 = pitcher's ERA
