Crowe will be recalled to start Game 2 of Friday's doubleheader against the Marlins, Jesse Dougherty of The Washington Post reports.
The 26-year-old has made two spot starts for the Nationals this season and will make another one as the 29th man for Friday's twin bill. Crowe has allowed five runs on 10 hits with a 5:6 K:BB over six innings across his first two big-league outings.
