Mitch Keller was one of the most rumored trade targets for the Chicago Cubs ahead of the MLB trade deadline, and there was a sense that the Cubs may turn to Keller and the Pittsburgh Pirates if their trade efforts elsewhere didn't materialize. Of course, as we now know, it seems the Cubs had extreme reservations about moving any of their top prospects at the deadline.
While Keller was among the group of controllable starting pitchers who didn't move at the deadline, a recent report suggests there was some late movement toward a potential deal--and it didn't involve the Cubs.
