The Royals have freshened up their bullpen after a 15-inning loss to the Orioles, sending Nate Adcock and Vin Mazzaro to Triple-A Omaha and recalling Everett Teaford and Louis Coleman on Thursday.
Kansas City made the moves before its afternoon's game against Baltimore and less than 12 hours after a 4-3 defeat in which the Royals squandered a two-run lead in the ninth inning.
Adcock pitched five innings of relief in Wednesday night's game. He was responsible for Adam Jones' eventual game-winning homer in the top of the 15th. Mazzaro earned the win after five innings in a spot start against Texas on Tuesday night.
Teaford and Coleman have spent much of the season with the Royals. They were in Omaha before being recalled.
The Storm Chasers host Tacoma Thursday night at Werner Park.
