Peters allowed two runs on three hits and three walks while striking out five across four innings during Tuesday's win against the Tigers. He did not factor into the decision.
Peters, who was activated off the injured list ahead of Tuesday's start, missed the minimum 10 days with back troubles. The 29-year-old experienced a troublesome third inning during which he allowed an RBI triple to Derek Hill and an RBI single to Robbie Grossman. Otherwise, Peters held things together enough to align the Pirates for an eventual win. Since getting called up from Triple-A Indianapolis, the southpaw has compiled a 3.38 ERA and 1.29 WHIP across 18.2 innings.
