This tool provides a standardized method for evaluating a pitcher’s effectiveness when games are shorter than the traditional nine innings. It adapts the earned run average (ERA) formula, typically calculated over nine innings, to reflect performance in seven-inning contests. For example, if a pitcher allows two earned runs in a seven-inning game, the calculated statistic will differ from the traditional nine-inning ERA calculation.
Adapting the traditional ERA calculation is important because it allows for fairer comparisons of pitchers’ performances in contexts where game length varies, such as in certain levels of baseball or softball. It provides a more accurate reflection of a pitcher’s ability to prevent runs in the specific game format, facilitating more informed player evaluations and strategic decision-making. This adaptation gains prominence where seven-inning games are prevalent, offering a relevant performance metric within those contexts.
