Strahm was recalled from Double-A Northwest Arkansas on Sunday.
After spending the majority of the season as a starter, each of Strahm's last four appearances came in a relief role. The Royals seem to be impressed enough with his work to give the 24-year-old southpaw a shot at the major league level after allowing just one earned run over 6.1 relief innings. Strahm will likely serve in middle relief, with the potential to give the Royals multiple innings if necessary.
