Duffey will be recalled from Triple-A Rochester on Tuesday, Phil Miller of the Star Tribune reports.
Duffey is now scheduled to start Friday against the Indians. He's done well with Rochester this season, as he's built a 2.93 ERA and 1.19 WHIP after five starts. However, his ERA has swollen up to 6.24 in the majors, making Friday's contest against a high-scoring Cleveland offense a tough matchup for Duffey.
