The Pittsburgh Pirates top prospect is right-handed starter Mitch Keller. Keller has been on the rise in recent years and has been rated as one of the top overall prospects in baseball over the last two seasons. He is Rum Bunter’s, MLB Pipeline, and Baseball America’s top-ranked prospect in the Pittsburgh Pirates organization. He also is ranked by MLB Pipeline as the number 18 overall prospect in baseball.
The former second-round pick has gotten off to a bit of a rough start this year. He has struggled with his command in the early going and has not really gone very deep into games.
