Pitchers' Concerns is a term used in baseball to refer to the two main goals of a pitcher: to get batters out (OUTS) and to limit the number of runs scored (ERAS). The two crossword solutions, ERAS and OUTS, are both four-letter words that refer to these two goals. ERA stands for Earned Run Average, which is a statistic used to measure the number of runs a pitcher has allowed over a given period of time. OUTS refers to the number of batters a pitcher has retired during a game.
