Barriera is ramping back up towards bullpen sessions after being shut down for two weeks with elbow soreness, Mitch Bannon of SI.com reports.
Barriera has made four starts for Single-A Dunedin this season, striking out a third of the batters he's faced but posting a 5.40 ERA. He hasn't pitched since May 25 but has gotten back to throwing from 90 feet and should soon be cleared to throw a bullpen.
