McCullers (shoulder) will rejoin the rotation Friday against the Red Sox, Angel Verdejo of the Houston Chronicle reports.
After starting the season on the disabled list due to a sore throwing shoulder, McCullers is set to make his 2016 debut on Friday. He was sharp in his final rehab outing at Triple-A Fresno and he also noted that he felt ready for game action following his bullpen session Tuesday. Friday's start will be a bit of a baptism by fire for McCullers, however, as he'll be facing a Red Sox lineup that is averaging 6.3 runs per game in May.
