Earned run average (ERA) is a crucial statistic in the game of baseball. It measures the average number of earned runs a pitcher allows per 9 innings pitched. However, there are several synonyms for ERA that can be used interchangeably. One such synonym is "earned run average against." This phrase emphasizes the opposition that the pitcher is facing. Another synonym is simply "runs allowed average," which focuses solely on the number of runs allowed. "Pitching average" and "pitching ratio" are also sometimes used, though they are less common. Ultimately, no matter what term is used, ERA remains a key measure of a pitcher's skill on the mound.
