Drillers manager Kevin Riggs said at the end of the last homestand, "All that he's done since the Rockies signed him is get people out. The way he pitches makes a statement for himself. I know our people like him and I've had other managers ask me about him."

Most of Winkler's pitching this season has been done on the road, but his next two starts are scheduled for ONEOK Field. His next appearance is slated against the Springfield Cardinals at 12:05 p.m. Wednesday at ONEOK Field.

There has been a lot of speculation about when Gray and Butler are going to be promoted, but Winkler also may not be with the Drillers much longer if he continues to dominate in the TL.

Bundy nears return: Another top prospect, Owasso graduate Dylan Bundy, is scheduled to throw batting practice with the Baltimore Orioles on Tuesday after two successful 50-pitch bullpen sessions last week as he comes back from undergoing Tommy John-elbow surgery last June 27. It will be his first time facing hitters since 2013 spring training.
