Glasnow (arm) left Sunday's game with an apparent arm injury and will be checked out Monday in Pittsburgh, Cory Giger of the Altoona Mirror reports.
Glasnow completed three innings, allowing two runs on two hits and three walks while striking out five. The righty last appeared in a game July 23 before leaving with shoulder discomfort. He makes for a great prospect in keeper leagues, but this potential setback could negatively impact his status for the rest of 2016.
