What is a common statistic used to measure a pitcher’s effectiveness in NCAA softball?

Earned run average (ERA) is a widely used statistic that provides a clear measure of a pitcher's effectiveness by calculating the average number of earned runs a pitcher allows over a set number of innings pitched, typically measured per seven innings in softball. A lower ERA indicates a pitcher is more effective at preventing runs, which is crucial for a team's success.

This statistic is significant because it directly reflects only the runs that can be attributed to the pitcher's performance, excluding unearned runs, which occur due to defensive errors. By focusing on earned runs, ERA gives a more precise evaluation of a pitcher's skill in limiting scoring opportunities for the opposing team.

In comparison, while home runs allowed is also useful, it only focuses on one aspect of a pitcher's performance rather than providing an overall assessment. Total strikeouts are important, but only looking at strikeouts ignores other critical elements like walks, hits, and runs allowed. Similarly, batting average against provides insight into how frequently opposing batters get hits off a pitcher but does not encompass the overall effectiveness of their performance in terms of run prevention. Thus, earned run average is the preferred statistic for evaluating a pitcher's contribution to their team's success in NCAA softball.
