Glasnow has been placed on the 15-day DL due to right shoulder discomfort.
Glasnow's start Saturday was rocky at best, as the command issues that the right-hander exhibited in the minors came back to haunt him to the tune of three walks and two hit batters. At least this time, shoulder discomfort is to blame, as he left that start in the fourth inning due to the ailment. Glasnow was likely headed for Triple-A anyway, but this move will allow the Pirates to keep him on the active roster, so they won't need to exercise one of his options if they decide to put him back in the rotation upon his return.
