EDGE Analysis

Ober earned a victory in his first start of the season Sunday against the Nationals by allowing only one run and striking out four over 5.2 frames. He'll return to the minor leagues with Kenta Maeda (ankle) cleared to start Wednesday's matchup with the Yankees. The Twins are expected to make a corresponding move Tuesday, per Park.
