The Boston Red Sox are set to have their top pitching prospect, Payton Tolle, make his MLB debut against the Pittsburgh Pirates on Friday night, as confirmed by multiple sources. Tolle, a 6-foot-6 left-hander and the No. 28 overall prospect in MLB Pipeline, has shown impressive performance in the minors, recently posting a 1.67 ERA in Double-A and a 3.60 ERA in Triple-A, though he has yet to pitch more than five innings in a game.
