ERA vs Earned Runs
Formule
## How ERA Is Calculated ### Formula **ERA = (Earned Runs / Innings Pitched) x 9** ERA normalizes to a 9-inning game so you can compare pitchers with different workloads. ### Benchmarks - **Below 3.00**: Excellent (ace-level) - **3.00-3.50**: Very good - **3.50-4.00**: Above average - **4.00-4.50**: Average - **Above 5.00**: Below average
Exemple Résolu
A pitcher allowed 30 earned runs in 100 innings.
- 01ERA = (30 / 100) * 9 = 0.30 * 9 = 2.70
- 02This is an excellent ERA
Questions Fréquentes
What is the difference between earned and unearned runs?
Earned runs are scored without the benefit of an error or passed ball. Unearned runs result from defensive mistakes and do not count in ERA.
What is a good ERA?
In modern baseball, an ERA below 3.50 is very good for starters. Relief pitchers often have lower ERAs due to shorter appearances.
How do thirds of innings work?
In baseball notation, 6.1 innings means 6 and one-third innings. For ERA calculation, use 6.333. Similarly, 6.2 = 6.667.
