Zack Greinke

Few players in the nation have helped themselves as much as Greinke, who entered the year as a potential second- or third-rounder and now figures to go in the first 8-15 picks. An outstanding athlete who's part of a typically strong Clemson recruiting class, he's a legitimate prospect as a third baseman and holds most of Apopka High's career batting records. But teams are focusing on his mound prowess, which includes a 92-93 mph fastball that has touched 96, a plus changeup and a good breaking ball. He commands all three pitches very well, and scouts like his poise and mental toughness.
