Compute ERA in baseball is a fundamental statistic used to assess a pitcher's performance. It quantifies the average number of earned runs a pitcher concedes per nine innings pitched. The ERA formula is:
ERA = (Earned Runs / Innings Pitched) * 9
Here, "Earned Runs" denotes runs attributed to the pitcher's performance, while "Innings Pitched" is the total innings the pitcher has played.
A lower ERA signifies a more effective pitcher, while a higher one implies less effectiveness. ERA plays a pivotal role in evaluating both individual player prowess and team strategy in baseball, serving as a key metric for assessing pitching performance and aiding in strategic decision-making.
