"I just hope he enjoys the experience," Callaway said on Wednesday morning. "If he's feeling OK and feels like he can go and he wants to pitch, obviously he's eligible."
Asked if Salazar had a case to be named the American League starter, Callaway was quick to praise White Sox ace Chris Sale.
"Chris Sale's pretty good," Callaway said. "He's done pretty good. He probably deserves it. Danny's done a great job, too, but Chris Sale probably deserves to start."
So far this season, Salazar has gone 10-3 with an AL-low 2.
