Glasnow, who struck out nine batters Saturday but needed 95 pitches (including only 51 strikes) to navigate through 4.2 scoreless innings, experienced a stiff back against Syracuse, Pirates Prospects reports.

While the back injury is thought to be minor, Indy manager Dean Treanor was unhappy with Glasnow's propensity to look for the strikeout against every batter. "Challenge them," Treanor said. "He has to get out of thinking I have to strike everybody out. In the first inning. You can't do it here and for sure can't do it (in Pittsburgh)." With Gerrit Cole (triceps) potentially hurt and the team's rotation struggling, Taillon has an opportunity to pitch in Pittsburgh before too long. That said, he'll have to throw more strikes before management gives him a chance.
