The Rockies are still searching for pitchers that can find success in hitter-friendly Coors Field. Certainly some of their Top 20 Prospects could help in the club's annual quest for arms.
Jon Gray | RHP | 6-foot-4, 235 pounds | No. 1
Gray is part of a dynamic duo of pitchers the Rockies hope will anchor their staff for years to come. Gray has it all -- a power arm with a fastball that hits 95-97 mph regularly and 100 if needed, a very good swing-and-miss slider and a changeup that can buckles knees. He has good control and command of his entire repertoire. He has the potential to be an ace and he may need more development time, but his upside tempts a promotion.
