A righthander buried a bit too deep in the Blue Jays refreshed farm system, Aaron Sanchez struck out a batter per inning while moving from rookie ball to low-A Vancouver in 2011, then looked even better at A-level Lansing in 2012. Spending all of 2013 at high-A Dunedin, Sanchez posted a 1.19 WHIP in 86 innings while racking up a satisfactory 75:40 strikeout-to-walk ratio. His mid-90's fastball can reach the high-90's on occasion, though it moves better when thrown at less than maximum velocity. When located well it can be quite devastating, making his second pitch (a quality curve) not very necessary. The changeup isn't all there yet, but that's typical in young arms. Sanchez will be working on repeating the delivery of all three pitches this year once again. The sign everyone is watching for is improving control: if he can contain or further-reduce his walk rate, he's big-league ready and should spend the bulk of the year in the majors. If not, he'll be up and down until he can do so.

The switch-hitting son of the better-known outfielder, shortstop Raul (Adalberto) Mondesi is already familiar with a major league dugout, even if it's only as a place to find a treasure trove of sunflower seeds and bubble gum. While he lacks his father's power profile, Junior does have a quality bat, superior speed and sure seems to have sophisticated defensive skill. A smallish player, he looks apt to stick at shortstop, where he could grow into some sort of slappy table-setter for the Royals a few years from now. He's still some distance away from showing anyone exactly how good he'll be, but an impressive .290/.346/.386 line as a
sixteen-year-old in rookie ball was followed by a .261/.311/.361 line in A-ball last season. A substantial improvement in his strikeout rate, despite dealing with better pitching, impresses us even more than that. Forget the name-recognition, Adalberto Raul Jr. is legit all on his own.

A tall, thin pitcher being developed in the Padres system, Ohio native Matt Wisler looks every bit a future rotation anchor. In 20 AA starts last season, Wisler struck out almost exactly one batter per inning while walking barely more than one per game. That's exactly the sort of performance that the control-obsessed Padres love to see, and it's enough to put him in the mix for MLB consideration in mid-to-late 2014.
Wisler works a couple of different low-90's fastballs with accuracy to both sides of the plate, but it's his slow curve that turns heads and misses bats most often. How he'll perform against better opponents is an open question, but if he continues his careful, clever approach while trusting his stuff, he should succeed.

Yet another quality shortstop prospect from a system that suddenly can't stop producing them, Venezuelan Jose Peraza follows Pastornicky and Simmons, Salcedo and Ahmed into the Braves spotlight. Peraza has an all-around strong offensive toolset, hitting for average and with good gap power while also showing plus speed and savvy on the bases. He slashed .296/.350/.374 and stole 25 of 30 bases while moving up from Danville to the GCL last season. In the field he looks like a true shortstop, with the range and arm to stay at the position. He'll try to bring his hard-nosed and smart approach to A-ball in 2013.

The consensus best hitting prospect available in the 2014 draft, Alex Jackson was drafted and signed by the Mariners after hitting an even .400 (with a 1.459) OPS in his last year at Rancho Bernardo High School. Nominally a catcher, the Mariners are much more likely to accelerate his development by moving him to the outfield, where his bat will bring him to the Major Leagues much more quickly. Reportedly a student of the game, he'll no doubt struggle a bit while learning a new position, but he should have no real issues adjusting to any other challenge the low minors can offer. While his swing can get just a bit long at times, there's nothing to suggest he won't still be a better-than-average righthanded contact hitter with true plus power by the time he reaches MLB, and that's something the Mariners would love to have in the lineup.

A square, powerful righthander from the University of San Francisco, KC pitcher Kyle Zimmer's calling card is his 98mph fastball, which he brings from a great rock-solid arm angle. It dazzles hitters from either side of the plate thanks to late life and movement. It's Zimmer's selection of other pitches, though, all of which look to be near-MLB ready, that will get him to the Show to stay. Give him another year or so, and you'll have a top-shelf pitcher on your hands.

He might sound like a designer of cheap neckties, but prospective Ranger catcher Jorge Alfaro has been making a name for himself in the damp northwest rather than the fashion outlets in airport shopping malls. A big strong right-handed bat, the still-teenaged Alfaro looks likely to stick behind the plate, where he exhibits a cannon arm of increasing accuracy. His game-calling skills are a long way off, but if that .320/.430/.750 Sally League line from 2012 is a real indicator of his potential, the Rangers will be content to wait it out.

Georgia high schooler Austin Meadows is an outfield phenom who attracted a great deal of first round attention in MLB's 2013 first-year player draft before falling to the Pirates with the ninth overall selection. A phenom with five tool talent, Austin is one of the fastest baserunners in the country, with speed that would make him one of the fastest players in pro baseball if he can get the rest of his game to half that level. His swing is promising, featuring a smooth and easy load with the makings of real plus power from the left side. He's been compared to players like Andre Ethier and Jacoby Ellsbury, and not without reason: few ballplayers blend across-the-board abilities like this. The only thing that might keep him from a minor league roster is 2014 is his commitment to Clemson University.

A long and lean righthander from Texas, Kohl Stewart is the embodiment of pitching potential, and as long as he remains a Twin, he's got a very good chance at reaching that potential. His stuff is very raw, and other than his slider doesn't do much, but his fastball was already cracking 90mph as a high-schooler, which means there are almost certainly a few more ticks to come. As a starter for St. Pius X in Houston, Stewart made eight starts (40 innings) in which he struck out 59 and walked 16. (His ERA was an hilarious 0.18). A multi-sport athlete, he's also done very well as a football player (as a high school senior, he threw for 2,560 yards and 28 touchdowns). In a small taste of pro baseball last season, Stewart struck out 24 Rookie league batters in 20 innings of work while walking only four. He'll step up slowly, first to A-ball in 2014, and the Twins will take their sweet time making sure he earns every promotion along the way.

A fast, slappy hitter with good speed and plus defense, Rockie prospect David Dahl looks like a good fit for the 'new' Coors Field, where speed is a special asset. He's more than a raw tools candidate, though: Dahl uses his speed well on the bases and in the field, and shows a good eye for situational hitting. For such a young player, he's quite polished already, though he'll need a couple more seasons in the minors to really reveal his true level.
