EARN RUN AVERAGE Meaning and
Definition
-
Earned run average (ERA) is a statistical measure used in baseball to determine the average number of earned runs given up by a pitcher over the course of nine innings. It is widely regarded as an important metric for evaluating a pitcher's performance and effectiveness. The formula used to calculate the ERA takes into account the number of earned runs allowed by the pitcher and the number of innings pitched.
Earned runs refer to runs scored off a pitcher that are not caused by defensive errors or mistakes. They are typically the result of hits, walks, or home runs allowed by the pitcher. ERA is calculated by dividing the total number of earned runs by the total number of innings pitched, and then multiplying the result by nine.
A lower ERA is considered more favorable, as it indicates that the pitcher is giving up fewer earned runs on average. For example, an ERA of 2.50 means that the pitcher gives up an average of 2.5 earned runs per nine innings pitched. ERA provides insight into a pitcher's ability to prevent opposing teams from scoring runs. It helps compare pitchers on different teams and evaluate their performance relative to other pitchers.
ERA is a key statistic used by scouts, coaches, players, and analysts to assess a pitcher's overall effectiveness and skill level. It serves as an important tool in determining the value of a pitcher and their contribution to a team's success.
