Wilson is scheduled to start Tuesday's game against the White Sox in Chicago, Daryl Van Schouwen of the Chicago Sun-Times reports.
Wilson returned from the injured list Wednesday against the Diamondbacks and tied his season high with seven strikeouts while working five scoreless frames, so it comes as little surprise that he'll stick around in the Pittsburgh rotation. After acquiring Wilson from Atlanta on July 30, the Pirates presumably want to evaluate him throughout September to determine if he's a long-term fit in their rotation.
