The Cubs claimed Wilson off waivers from the Phillies on Wednesday, Meghan Montemurro of the Chicago Tribune reports.
The Cubs' pitching staff has been hit hard by injuries, so Wilson could be used either in the rotation or as a long reliever. Wilson tossed two scoreless frames in his one appearance for the Phillies this season and holds a 6.29 ERA and 58:21 K:BB over 54.1 innings at the Triple-A level.
