The Twins selected Hildenberger's contract from Triple-A Rochester on Friday.
The right-hander has mowed down opponents for Triple-A Rochester to the tune of a 2.05 ERA, 35 strikeouts, eight walks and six saves across 30.2 innings. Hildenberger, 26, brings intrigue to a Twins bullpen lacking excitement. It may not take him long to ascend the depth chart and lock down a high-leverage role, considering he recorded double-digit saves at three minors levels prior to this season.
