The Tigers reinstated Outman (concussion) from the 7-day injured list Sunday and subsequently designated him for assignment.
The 29-year-old spent just over a week on the concussion IL but won't stick on Detroit's active roster now that he's healthy. Outman was claimed off waivers from the Twins in mid-June, but the Tigers have apparently seen enough after he posted a .183/.240/.366 slash line and 42 percent strikeout rate in 45 games.
