After missing the first six weeks of the season with a hamstring injury Chien-Ming Wang will come off the disabled list tonight, according to Mark Zuckerman of CSNWashington.com.
Wang volunteered for relief duty if the Nationals felt he was a better fit there and indeed they’ve opted to stick with Ross Detwiler as their fifth starter. Wang has never been a full-time reliever, making just five of his 120 career appearances out of the bullpen, and he seems likely to be used in low-leverage situations.
To make room on the roster and in the bullpen for Wang the Nationals will place reliever Ryan Mattheus on the DL with plantar fasciitis in his left foot, which has apparently been bothering him for weeks despite a 2.25 ERA in 20 innings this season.
Mattheus told Zuckerman that he’s hoping to return after the minimum 15-day DL stint and by then the Nationals should have a much clearer idea of whether Wang can contribute as a reliever.
