Wacha (shoulder) has been activated from the disabled list, Jenifer Langosch of MLB.com reports.
After nearly a month of the disabled list, Wacha will rejoin the Cardinals for the final few weeks of the regular season. While he's served exclusively as a starter to this point in 2016, Wacha will be used out of the bullpen for the time being. The 25-year-old holds a 4.45 ERA and 1.42 WHIP on the year.
