Musgrove threw six innings in a minor-league game Saturday with no issues, Bill Brink of the Pittsburgh Post-Gazette reports.
Musgrove is slightly behind schedule after dealing with a shoulder injury early in camp, but he appears to be on the cusp of a return. The right-hander got up to 92 pitches in Saturday's outing and reported feeling fine afterwards, essentially clearing the way for him to make his 2018 big-league debut. The Pirates haven't confirmed Musgrove's next step, but he's currently lined up to start against the Reds on Thursday.
