Ort was recalled from Triple-A Worcester on Friday, Ian Browne of MLB.com reports.
Ort will rejoin the Red Sox's bullpen as a result of Kutter Crawford (hamstring) landing on the 15-day injured list Friday. Ort has struggled in 12 major-league appearances this season, holding a 7.30 ERA and 1.78 WHIP across 12.1 frames.
