The Twins optioned Sands to Triple-A St. Paul on Sunday, Betsy Helfand of the St. Paul Pioneer Press reports.
Minnesota will replace Sands in the bullpen with a fresh arm in Jharel Cotton, whose contract was selected from Triple-A in a corresponding move. Sands worked 3.1 innings in relief of Chris Archer (pectoral) -- who was placed on the injured list Sunday -- in Saturday's 6-4 loss to the Guardians, giving up three earned runs on two hits and five walks.
