Povse (hamstring) allowed three hits and three walks while striking out two during 3.1 innings with Double-A Arkansas on Wednesday.
This marks Povse's first appearance since landing on the disabled list in late May. Although he started Wednesday's contest, the Mariners are in the process of converting the 23-year-old to a bullpen role. If all goes well, Povse could be on a fast track to the majors as a reliever.
