Duffy has been moved to the bullpen, Andy McCullough of the KC Star reports.

EDGE Analysis

Duffy is winless in his last four starts, and he was tagged for four earned runs on six hits in just 2.1 innings in Wednesday's loss to Cleveland. The Royals will move Jeremy Guthrie back into the rotation in Duffy's place, but McCullough's report notes that Duffy will still be competing for a spot on the postseason roster.
