The Pirates called up Peters from Triple-A Indianapolis prior to his scheduled start Sunday against the Brewers, Jake Crouse of MLB.com reports.
Pittsburgh moved Bryse Wilson (general soreness) to the 10-day IL in a corresponding move, and Peters will presumably step in as a replacement in the rotation while the former is sidelined. Over 132.2 career innings in the majors, Peters owns a 5.83 ERA and 6.9 K/9.
