Thielbar was placed on the 15-day injured list Friday with a right oblique strain, Betsy Helfand of the St. Paul Pioneer Press reports.

EDGE Analysis

Thielbar just returned from the same injury this past weekend and made just one appearance before evidently suffering a setback. He missed more than a month with the injury the first time around. Josh Winder is taking Thielbar's spot in the bullpen.
