Thanks for that, Nate! It depends on the guy. They've been incredibly patient with Pie, promoting him one step at a time, one year at a time. However, they've been happy to call up guys like Murton, Greenberg, Gallagher, Marshall, and Marmol despite a relative lack of experience in the upper minor leagues. Most of the time, the Cubs tend not to challenge guys with promotions and are instead content to keep them at the same levels all season; especially if their team is in a potential playoff hunt or if it's a guy's first full season of baseball. They tend to promote relievers quickly, though.
