Mitch Keller and Roansy Contreras are the best long-term starting pitchers the Pittsburgh Pirates have in the upper levels.
Mike Burrows and Quinn Priester are the best starting pitching prospects the Pirates have in the upper levels.
For this edition of Prospect Roundtable, we're going to assume that all four of those pitchers reach their upsides, or at least give the Pirates a solid #1-4 in their rotation. That's a huge assumption, considering the attrition rates of pitching prospects. I told everyone this week to assume away on those four players, and pick the starting pitcher who could round out the MLB rotation.
