The return is not yet known, but the Mariners added a left-handed arm to the middle of their bullpen while the Twins dealt a 35-year-old on an expiring contract. Duke's value will increase in formats that reward for holds and remain unchanged in most other formats. He has a 3.62 ERA and 39 strikeouts in 37 1/3 innings this season.
