Earned Run Average (ERA) Explained
Formula
ERA measures how many earned runs a pitcher allows per nine innings, making it the standard metric for evaluating pitching performance. Lower ERA values indicate better pitching.
An ERA below 3.00 is considered excellent in modern baseball, while the league average typically falls between 3.80 and 4.50.
Common use cases:
- Pitcher performance evaluation
- Comparing pitchers across teams
- Fantasy baseball scoring
