Casey Cox, shown here on card number 82 of the 1971 Topps set, was the swing man on the Washington pitching staff in 1971. Casey made 54 appearances for the Senators with 11 of those being starts and the rest in relief.
In those 54 appearances Casey pitched 124.1 innings and posted a 3.98 ERA. That was the highest ERA in the Senators regular bullpen that year but Casey also pitched more innings than anyone else in the pen. It was also .47 lower than his ERA the previous season. Of the 543 batters he faced (also highest in the bullpen) Cox struck out 43 of them. He did walk 40 though and his WHIP climbed to 1.375.
Even with the struggles, Casey had rebounded nicely from his
then career worst season in 1970. What remained to be seen was if he could build on that rebound and get his career back on track in Texas.
