Seen by many as the best pitching prospect of the 2013 draft class, Oklahoma's Jonathan Gray is a towering righthander with high-90's heat that breaks 100mph from time to time. More often, he throws it at 94 or 95 with good late movement that busts righthanded hitters. His real showcase pitch, though, is the hard slurvy slider that comes in near 90mph but drops dramatically off and away, making even good hitters look like weak-kneed noodle-slappers. If Gray has a weakness, it's his not-there-at-all changeup, a pitch he may need if he's going to handle lefthanded hitters with as much skill as he deals with righties. Regardless, he's a top flight prospect who has the stuff and maturity to handle pitching, even at Coors Field.

A sometimes-dominating college starter who struggled with control issues from time to time, Colorado prospect Eddie Butler was drafted in 2012's supplemental round on the strength of his best performances, in which he looked downright unhittable. Butler somehow produces a 98mph sinking fastball from a smallish and lightweight frame, and manages to command it well to both sides of the plate despite (or thanks to) its late life. His more traditional breaking balls are less consistent, but if the Rockies can help him to add even average command to his toolset, he'll be a powerful starter or reliever in the near future.

A prototypical hard-throwing Texas righthander, high-school prospect Tyler Kolek was taken by the Marlins as the second overall pick of 2014. The fastball that springs from his large, sturdy body often scrapes 100mph, and when he mixed it with a solid 12-to-6 curve, he can be almost unhittable. He's also added a slider recently, a nasty high-movement offering that's already better than most in the minor leagues. While there's no real changeup on the horizon, it might not matter: he's already more than capable of keeping batters uncomfortable and off-balance in the box. If there's a warning label on Kolek, it might be on his high-maintenance mechanics, which might suggest repeatability and command issues down the road.

Selected by the Reds in the first round of the 2011 Draft (27th overall), righthander Robert Stephenson was a rare high-school choice from the usually conservative Cincinnati franchise. The tall Californian overpowered his peers in his senior high school season, posting a 1.19 ERA in 76 innings that included not one but two no-hitters. A power pitcher in the classic mould, he can already top 98mph with his fastball. As always, though, it's how well his secondary pitches develop that will determine his fate in pro baseball. So far, all signs point to a 2014 opportunity

The younger of Baltimore's Bouncing Baby Bundies, the growly-looking Dylan is a righthander with ace upside, but he remains relatively untested against pro hitters, and under professional pressure. His ungodly 0.25 ERA and 158 strikeouts in 71 innings as a high school senior earned him honors as the Gatorade National Baseball Player of the Year, BA's High School Player of the Year Award and USA Today's National Player of the Year. That said, he's still what we in the business like to call
a high school pitching prospect, which is a term of art meant to indicate that this category of gamble is among the riskier bets in baseball. His fastball/cutter combination is a genuine plus combo, and he's been improving his command and control while working on improving his changeup in the minors. He'll need that to succeed. The Baltimore organization has done nothing in the last few years to suggest they're not one of the very best incubators for pitching talent, so overall, we're still believers.

A lefty who can touch 96mph with a sizzling fastball, Toronto's Daniel Norris is a bit of a sleeper who should be gaining a lot more attention in the months and years to come. Norris already complements his heat with a hammer curve that can be devastating, and if he manages to get a third pitch up to even major-league average, he'll be an ace on a team known for discovering gems.

A tall lefthander from California, Boston prospect Henry Owens is a raw but high-ceiling pitcher who many project as a future relief specialist, though he's shown the durability and maturity to survive as a starter. Owens fastball is a low-90's offering with movement, which should pick up a few more ticks on the radar gun as he grows and gains strength. At present, he usually mixes in two curves, one hard and one soft, with varying degrees of effectiveness, and a weak changeup that does almost no good whatsoever.
With command to improve and strength to build, Owens won't be an All-Star anytime soon, but his raw ability shouldn't be overlooked. Given another year or two of good guidance and hard work, he could find himself taking an MLB mound every fifth day, or at least for an inning or two twice a week.

A tall and lanky teenager who arrived in the DR in the winter of 2011, outfielder Jorge Soler is one of the most promising Cuban prospects in baseball today. He's already shown off his tools in Dominica, and while he looks like a centerfielder right now, physically, his height and young age make it quite possible he'll be a corner fielder when he finishes growing. And if his loopy power swing develops as expected, he'll hit like one too.
He's already showing signs of MLB videogame level power at the plate, and his very strong arm is certainly real. His iffy contact skills and lack of patience at the plate, though, are equally clear indicators that he's still a rather rough gem. One bonus for his future home in The Show: the youngster already has an electric personality in his toolbox, which means he could be a real cover boy come 2015 or so.

The son of mustachioed Angel closer Bryan Harvey, North Carolina's Hunter Harvey is a big righthander with a big fastball and a quality curve. The fastball comes in at low-90 readings, though it does touch 96 on occasion. The curve, though, is what makes Harvey exceptional. Prep pitchers aren't known for having quality secondary offerings, but Harvey's Hammer (trademark pending) is a beautiful one. Harvey's change is still coming along, but it's about as well-advanced as can be expected at such an early stage of his career. He looks to be the complete pitching package, and seems likely to work his way into the middle of an MLB rotation one day.
