Kyle Zimmer, RHP, University of San Francisco: A virtual unknown two years ago, Zimmer has developed into a terrific prospect, posting a 2.85 ERA with a 104/17 K/BB in 88 innings for the Dons this spring, allowing 75 hits. With an athletic 6-4, 215 build, Zimmer throws 93-98 MPH and has developed a strong curveball. His changeup needs some work and his location isn’t perfect, but his mechanics are solid and his arm is fresh for a college product. He occasionally leaves balls too high in the strike zone, which didn’t hurt him in college ball but might need some adjustment in the majors. The former third baseman is very athletic and still physically projectable. Some scouts (and the Royals, obviously) felt he was a better pitching prospect than Mark Appel and Kevin Gausman. He may need a bit more development than the average college pitcher drafted this high, but his upside is very impressive.
