The Nationals optioned Crowe to their alternate training site Wednesday.
Washington brought Crowe up from the alternate site to serve as its 29th man for Tuesday's doubleheader with the Phillies, but he wasn't needed out of the bullpen in either game. Unless the Nationals place another player on the injured list before their season finale Sunday, Crowe won't return to the big club and will finish the 2020 campaign with an 11.88 ERA and 2.64 WHIP over 8.1 innings.
