What is the Earned Run Average (ERA) in Major League Baseball (MLB)?
ERA is a statistic in Major League Baseball (MLB) that measures the average number of earned runs allowed by a pitcher per nine innings pitched. It is one of the most important statistics used to evaluate a pitcher's performance and is used to determine a pitcher's wins and losses.
To calculate ERA, you divide the total number of earned runs allowed by a pitcher by the total number of innings pitched. For example, if a pitcher has allowed 10 earned runs in 20 innings pitched, their ERA would be 5.00.
Earned runs are those that are scored by the opposing team due to the pitcher's performance, as opposed to unearned runs, which are scored due to errors or other defensive miscues.
