Jon Gray

Gray's metamorphosis from a live-armed but chubby high schooler to a potential No. 1 overall choice is reminiscent of Stephen Strasburg's. His stuff calls to mind Gerrit Cole, another top overall pick. Drafted in the 13th round out of an Oklahoma high school in 2010 by the Royals and in the 10th round out of Eastern Oklahoma State JC in 2011 by the Yankees, Gray steadily improved before exploding in his second season with the Sooners. After maxing out at 94 mph in high school, he now works comfortably at 94-97 and can hit 100 mph while looking like he's just playing catch. Gray's fastball also features heavy life. He shows the ability to dial it down to 92-94 in the middle innings before turning it back up toward the end of games, a la Justin Verlander. He has refined his slider into a wipeout pitch with depth and bite, and he can make hitters look silly with an improved changeup that bottoms out at the plate. Gray has firmed up his frame to a solid 6-foot-4 and 239 pounds, and he has his delivery and his pitches more under control than ever. He has maintained a high level of performance all spring, carrying an 8-1, 1.20 record with a 104-16 K-BB ratio and a .166 opponent average through his first 12 starts. If the Astros pass on Gray with the No. 1 selection, it will be an upset if he gets past the Cubs at No. 2.
