The Phillies selected Wilson's contract from Triple-A Lehigh Valley on Thursday.
Wilson hasn't been great at Lehigh Valley, authoring a 6.29 ERA and 58:21 K:BB over 54.1 frames. The 28-year-old will provide bullpen protection after the Phillies had to use six relievers and a position player on the mound in Wednesday's loss to the Marlins. Wilson is also a candidate to fill the rotation spot vacated by Andrew Painter's demotion, depending on how he's utilized in the coming days.
