Earned Run Average vs Earned Runs Allowed
Formule
## Earned Run Average (ERA) ERA is the average number of earned runs a pitcher allows per nine innings. It is the most traditional measure of pitching effectiveness. ### Formula **ERA = (Earned Runs / Innings Pitched) x 9** Only earned runs count (errors by fielders are excluded). A lower ERA is better. In modern MLB, an ERA below 3.00 is excellent, 3.00-4.00 is above average, and above 5.00 is poor.

Questions Fréquentes
What is a good ERA?
In MLB: below 3.00 is elite (Cy Young level), 3.00-3.50 is excellent, 3.50-4.00 is above average, 4.00-5.00 is average, and above 5.00 is below average.
What counts as an earned run?
An earned run is any run that scores without the aid of fielding errors. If a runner reaches base on an error and later scores, that run is unearned.
Is ERA the best pitching stat?
ERA is widely used but has limitations. Modern analytics prefer FIP (Fielding Independent Pitching), which isolates strikeouts, walks, and home runs from fielding quality.
