A precise tool.
What is the Foc & How does it work?
Earned Run Average (ERA) is a core pitching statistic in baseball that measures the average number of earned runs a pitcher allows per nine innings pitched.
A lower ERA indicates more effective run prevention, making it a key metric for evaluating a pitcher’s performance over a season or a single game.
Understanding how ERA is calculated helps fans and analysts compare pitchers across different leagues and eras, as the formula normalizes run allowance to a standard nine‑inning game.
