Sands (shoulder) is beginning a rehab assignment with Triple-A St. Paul on Wednesday, Brandon Warne of Access Twins reports.
Sands had posted a 0.73 ERA with 13 strikeouts in 12.1 innings of relief for the Twins before he landed on the injured list in early June due to a right shoulder impingement. He could be an option again for the Minnesota bullpen sometime next week.
