ERA · Earned run average
What is ERA in softball?
ERA (earned run average) is how many earned runs a pitcher allows per seven innings — softball uses seven because a regulation game is seven innings, not nine.
How to calculate ERA
ERA = (earned runs × 7) ÷ innings pitched
A pitcher who allows 6 earned runs in 28 innings has an ERA of 1.50.
What's a good ERA?
In pro softball, under 2.50 is good, under 2.00 is very good, and under 1.50 is elite.
Good to know
- Earned runs exclude runs that score because of errors or passed balls.
- Because softball ERA is scaled to 7 innings, it isn't directly comparable to baseball ERA.
