MINNEAPOLIS -- Left-hander Danny Duffy is on course to start on Thursday night against the New York Yankees at Kansas City.
Duffy tested his left elbow in a bullpen session on Sunday and had no recurrence of the stiffness that caused him to miss his scheduled start last Friday night against the Twins.
"He says he feels fine," manager Ned Yost said. "He passed the test today."
