The Royals will be getting players to be named later for Duffy, sources told Passan.
Duffy, who is currently on the injured list with a flexor strain, has no-trade protection that he’s expected to waive. He will be a free agent this winter.
The 32-year-old veteran has spent his entire 11-year career with the Royals, who drafted him in the third round of the 2007 MLB draft.
Duffy is 4-3 with a 2.51 ERA and 65 strikeouts in 61 innings pitched for the Royals this season. He is 68-68 with a 3.95 ERA in his career.
