Glasnow will take the hill for the Pirates on Thursday against the Cardinals, Rob Biertempfel of the Pittsburgh Tribune reports.
A report from ESPN's Buster Olney earlier Wednesday suggested Glasnow would be up soon, and now it appears the team has confirmed the date of his start. He'll get a tough draw in his major league debut, taking on Adam Wainwright and the Cards in a road matchup. The Pirates now have their rotation set up until the All-Star break, but it's unclear if Glasnow will remain a part of that picture following the Midsummer Classic.
