The Royals plan to bring up Danny Duffy to start against the Texas Rangers on Wednesday night in his major league debut.
Duffy, a 22-year-old right-hander, is 3-1 with a 3.00 ERA in seven starts and 36 innings at Triple-A Omaha. He is among many highly rated prospects the Royals have been bringing along in a minor league system rated among the best in baseball. The Royals will select his contract from the Triple-A Storm Chasers.
On Monday night, following a 19-1 loss to Cleveland, the Royals announced that right-hander Vin Mazzaro was being optioned to Omaha and left-hander Everett Teaford was being recalled.
