KANSAS CITY, Mo. -- The Royals have placed All-Star catcher Salvador Perez, right-hander Nate Karns and two others on the disabled list in a series of roster moves ahead of their opener against the White Sox.
The moves created space for the Royals to select the contracts of right-hander Blaine Boyer and infielder Ryan Goins, and recall catcher Cam Gallagher from Triple-A Omaha.
Perez is expected to miss up to six weeks after hurting his knee Tuesday night while carrying luggage in his house. Karns has elbow inflammation, Mondesi has a right shoulder impingement and Starling has a left oblique strain.
