The Pirates claimed Wentz off waivers from the Tigers on Tuesday.
Wentz was used as a full-time reliever this season for the first time, holding a 5.37 ERA and 60:27 K:BB over 55.1 innings. The left-hander is under team control through 2029 and is still just 26, so the Pirates thought he was worth a shot. Wentz is out of minor-league options, so he will report directly to the major-league club.
