The Pittsburgh Pirates are unlikely to call up prospect Tyler Glasnow in the month of September.
Glasnow has made six starts at the Triple-A level, posting a 0.81 ERA and striking out 10.5 batters per nine innings.
"Left the door open because he's doing some really good things, but he continues to remind us there are still some things he needs to do," Neal Huntington said. "At this point he is not on our radar to come up here in September or October. We still feel there is development (needed).
"(Glasnow) is not in our plans."
He is walking 4.6 batters per nine at Triple-A.
