Glasnow walked just one batter in six innings Saturday, allowing two runs on four hits while striking out eight for Triple-A Indianapolis.
With Gerrit Cole (triceps) expected back in the rotation after the All-Star break, it remains to be seen how Pittsburgh handles its starters. Speaking on the Neal Huntington Show on Sunday, assistant GM Kyle Stark said that Glasnow's changeup -- a concern coming into the season -- has now become a weapon. Stark gave no timetable for Glasnow's major league debut, but did say that the towering righty is "knocking on the door."
