Glasnow, who threw a scoreless relief inning Friday, could return to the starting rotation before season's end, DK Pittsburgh Sports reports.
He could replace Ryan Vogelsong, who started Friday's tilt. Glasnow showcased great stuff against the Reds on Friday, hitting 98 mph while averaging 95.5 mph with his fastball -- a full three mph faster than in his last appearance. "What I liked tonight is he let the fastball go," manager Clint Hurdle said. "We hadn't seen 98. We saw it tonight."
