The final player drafted in the second round of 2014's First Year Player draft, Ronnie Williams is a smallish righthander. While his size didn't get him much consideration, his 98mph fastball certainly got him attention from the Cardinals, who signed him quickly and assigned him to their Gulf Coast facility for close observation and training. Many are already comparing Williams to the similarly-built Chris Archer, who not only found success in MLB, but found it very quickly. The Cardinals like Williams's easy, repeatable delivery, and their coaches detect an advanced feel for the curve and changeup. That means St Louis will develop Williams as a starter, with a bullpen assignment only a measure of last resort at this time.

Willy Adames is a textbook Dominican shortstop with a better bat than most. At the plate, he shows a mature, patient approach, using a short stroke to drive the ball to all fields. In the field, he has soft hands and a strong arm, though perhaps not enough range or speed to ever be an elite defender. Signed by the Tigers at 16, he's still looking like a shortstop today, though as with all such players, as his body fills out, he may end up outgrowing the position. If he does, it seems likely his bat will play well enough to lock down a third base job. He's still very young and raw, but he's one of the more intriguing shortstop prospects in the game today.

The thirteenth overall selection in the 2014 draft, San Diego infield prospect Trea Turner has the eye, bat and legs to be a premium tablesetter on top of an MLB roster someday. Better than the usual crop of defense-first players with speed, Turner also brings a plus contact bat and very good plate discipline to his game, at least when he doesn't get homer happy. Hopefully the Padres will remind Turner they don't need him to be a power threat: they'll be more than happy enough with the on-base skills and superior defense he's more equipped to deliver.

A well-rounded high school athlete who just happens to be a pitcher at the moment, Georgia native Spencer Adams was snapped up by the pitching-hungry White Sox in 2014's June amateur draft, and looks like one of the team's top prospects as a result. Adams already mixes a tight 95mph fastball and sharp slider, with a reasonable curve and changeup still in development. Scouts like Adams's lithe frame and loose, easy delivery, suggesting a higher likelihood of smooth, healthy development without setbacks or injuries. Since he's still very young, it also means he could gain more strength and velocity as he matures.

The Nats' second round pick in 2010, lefthander Sammy Solis brings a competent fastball and reasonable curve from a delivery that's almost sidearm, but it's his straight change that is his best, and that's the plus offering that should be his ticket to MLB success. He took a solid step toward that future in 2011, when he worked his way up from A-ball into high-A Potomac, posting a 6-2 record with a 2.72 ERA and a nice 1.28 WHIP at the higher level.

An Iron Mike style strike throwing machine from Venezuela, righthander Jose Campos looked awfully polished in his first taste of Yankee ball in 2012, averaging a 1.15 WHIP across five A-league starts before succumbing to injury. Campos's 95-98mph fastball comes with pinpoint control, making him more of a strikethrower than a stuff pitcher at present... not that that's anything at all to complain about.
If he can grind his way through the A levels this year while refining his course curve and so-so slider, and can maintain even half his crazy strikeout to walk rate, he should be primed for AA in 2013. Seattle was so full of premium pitching prospects that they decided to shed Campos in the effort to pick up slugger Jesus Montero in 2012's spring. In New York, Campos can and should still simmer another year or two.

A Cuban outfielder who signed late in 2012, Baltimore prospect Henry Urrutia is a line-drive hitter with pretty good discipline (for a Cuban hitter). The son of Cuban star Ermidelio Urrutia, Henry lacks plus speed but isn't a liability on the basepaths, and while it's a question how much power he'll show in US ball, his .397/.461/.597 and twelve homer line in his final year in Cuba sure looks good from here. Of course, our rational side is more impressed with the 32:23 walk-to-strikeout ratio. He'll be tested in AA this year, though he may start in A ball first.

A very raw Dominican arm who can touch 99mph with his fastball already, eighteen year old Edwin Diaz is one of the most potent of a number of secret Mariner weapons for the future. While we're unlikely to see him until 2016 or so, he could be a force when he arrives. Stay tuned.

An thin but athletic southpaw with a nasty breaking ball to complement a well-controlled fastball, ex-Nationals prospect Robbie Ray projects as a potent bullpen weapon once he builds up his strength a bit. A 12th round draft selection, Ray has looked a lot better than that, striking out 86 A-level hitters in 105 innings of work at Potomac last season. He's still a couple of years away from any potential dominating performances in the Majors, but he's certainly a valuable asset, considering how quality lefty relievers are so hard to come by in MLB.

A late-blooming pitching prospect who's just now learning to pitch from his very big and strong frame after recovering from shoulder surgery a couple of years back, the Nationals' own Nathan Karns looks like he could step up into MLB soon. In 116 innings split between low and high-A ball last season, the right-handed Karns showed mastery of his 98mph fastball, turning in a scintillating 2.17 ERA, 1.01 WHIP season. A new ability to throw a quality curve for strikes and a developing change also helped him strike out nearly twelve batters per nine innings of work. A bit under the radar thanks to his advanced age, Karns could be a surprise savior if the Nats suffer injury this year. If not, he's on track for a storybook rookie debut at the age of 26 next season.
