Stewart (elbow) is expected back soon after the All-Star break, Jon Morosi of MLB Network reports.
Stewart went on the injured list last week with right elbow tendinitis and it sounds like he could have a minimum 15-day absence, or close to it. He's been a revelation out of the Twins' bullpen this season, posting a 0.70 ERA and 35:11 K:BB over 25.2 innings of work.
