The White Sox are moving Erick Fedde to the bullpen following their acquisition of Luis Castillo from Seattle. Ken Rosenthal of The Athletic reports that the White Sox are open to acquiring another starter even after the Castillo trade. The Sox have been tied to Reid Detmers, Clay Holmes and Shane Bieber — all of whom remain available. Sports reported earlier this week that the Sox had shown interest in Orioles left-hander Trevor Rogers as well. Adding another starter would allow the Sox to either use Schultz in relief or option him back to Triple-A Charlotte.
