Pirates director of sports medicine Todd Tomczyk said Wednesday that Peters (back) has resumed throwing, Kevin Gorman of TribLive.com reports.
Peters landed on the 10-day injured list with a lower-back strain last week, and he won't have enough time to ramp up his workload prior to the end of the regular season. The southpaw's injury carries a recovery timetable of approximately three weeks, so he should have a fairly normal offseason. Peters made six starts in the big leagues this year and recorded a 3.71 ERA and 1.35 WHIP in 26.2 innings.
