The Royals recalled Morgan from Triple-A Omaha on Thursday.
Morgan came up from Triple-A as the 27th man for Saturday's doubleheader against the Brewers, during which he gave up a hit and a walk while striking out five batters over three shutout innings. He'll now return to Kansas City alongside Mitch Spence to give the Royals a couple of fresh bullpen arms, replacing Luinder Avila and Steven Cruz.
