Sands was recalled from Triple-A St. Paul on Saturday.
Sands appeared in four games for the Saints after he was demoted July 28, throwing 5.1 shutout innings with 10 strikeouts. He'll work in a long relief role again with the Twins after Brent Headrick was sent to Triple-A after throwing 67 pitches over 3.1 relief innings in Friday's loss to the Phillies.
