Duffey (shoulder) has been confirmed as Saturday's starter against the Tigers, Mike Berardino of the St. Paul Pioneer Press reports.
He had a 1.72 ERA in three starts with Triple-A Rochester and is ready to pitch Saturday despite suffering a shoulder contusion earlier in the week. Duffey will stick in the Twins' rotation in the short term, but he may have to impress to hold a spot once Kyle Gibson and Ervin Santana return, likely sometime in May.
