Outman cleared waivers and was outrighted to Triple-A Toledo on Tuesday, Evan Woodbery of MLive.com reports.
The 29-year-old was reinstated from the concussion injured list Sunday and was then designated for assignment by Detroit, but he'll stick in the organization after passing through waivers unclaimed. Outman has struggled with both the Tigers and Twins this season, posting a combined .172/.235/.318 slash line and 41.8 percent strikeout rate in 94 games.
