A 4th round 2007 pick out of Newberry Park (Los Angeles) high school, first baseman Andrew Lambo fell lower than his talent dictated due to character concerns, but now that he's maturing, he's a civilized monster waiting to happen. The Dodgers preferred to use his all-around athletic ability in the outfield, but his new owners in Pittsburgh may reopen the question of Lambo as a future first baseman. In any case, he'll need to develop a little more contact ability if his power is going to have much impact: his .184 average across 60 AAA games last season wasn't exactly impressive.

A very raw pitching prospect from New Jersey, Angel prospect Joe Gatto is a sturdy righthander with good command of a sinking fastball and developing curve that occasionally flashes as a plus pitch. His command is very iffy thus far, however, and he has no useable changeup at present, so he's got some distance to go, here.

A big righthander in the pitching-rich Mariner system, young Carson Smith is seen by most scouts as a future closer. Working in the hitting haven of the Cal League in 2012, Smith posted an impressive 2.90 ERA and struck out 72 hitters in 60 innings of work, confusing batters with a mix of fastballs and changeups delivered with his signature whiplike arm movement. He'll step up to AA in 2013, and if he looks even close to that good again, could be in the Mariners' bullpen by September.

Venezuelan Yohander Mendez, an international signee inked by the Rangers in mid-2011, is a tall, skinny lefthander with a projectable frame and plus stuff. The most promising pitch in his arsenal is a raw but deep curve ball that he manages to throw with a motion that doesn't look all that different coming out of his hand than his 90mph fastball. He's currently hidden away in Mr Ryan's top-secret development laboratory learning how to handle his mutant powers, but when he's ready for his coming out he could be a good one.

A smallish power righty from SW Missouri State, Shae Simmons is seen by many as a future closer, thanks to his 96mph heater and hard slider. His changeup, a tumbling pitch that hitters flail at, is probably destined for the shelf if he continues to grow as a full-time reliever.

The younger brother of National Chris, shortstop Deven Marrero is a rising prospect in the Red Sox system, mainly on the strength of his defensive ability. Per one of his coaches, he's Omar Vizquel, but a better hitter and baserunner. That's pretty high praise to come off the cuff, so we'll have to wait and see, though in Marrero's defense, that .268/.358/.374 with 24/30 steals in his first tour of A-level Lowell is certainly an endorsement. If Jose Iglesias doesn't ever find a stick with which to hit, Marrero will become the chosen one.

A long, lean OF/1B prospect with a sweet (if long) swing, Adam Walker was drafted out of Jacksonville in 2012. The son of the NFL running back of the same name, Walker Jr has some of that body type, and his game plays as expected. A big, physical player with real upper-deck power, Walker's arm is below average and he isn't that adept at route-running, which nudges him all the way down to right field or first base on the defensive spectrum. He's been compared to Giancarlo Stanton, but his longer swing and better wheels look more like a righthanded Jason Heyward from here.

A two-way star in the Pacific Northwest, Phillies righthander Mitch Gueller is in for a different sort of future out East, where he'll need to learn to handle a lot more pressure than he's used to, and a full-time pitching career. Gueller can already touch 94mph with his fastball, and his breaking ball shows real promise, but he's a long, long way from being ready for Citizens Bank.

A quality lefthander who rose to attention via an outstanding performance in the Dominican Summer League, Rockie prospect Jayson Aquino is one of the safer bets in the system. With a solid, durable frame and an easy arm action, it's easy to see him moving up the system swiftly. His fastball lives in the low 90's with good movement and plus command, and his slider/curve (we're not sure what to call it yet) looks promising, but what's most exciting about Aquino is his changeup, one of the best in the Colorado system. When a player this young already has a change this good, it's a very very good omen.

A lefthander from the University of Minnesota, Tom Windle is seen by most as a lefty relief specialist, though he did make four starts for the Gophers last season as well. His 37:17 strikeout to walk ratio (in 41 total innings) was seen by many as a disappointing line, but his velocity actually improved as the season wore on, and he looked beter still in the summertime Cape Cod League, where better command led to a much better 47:7 ratio and a shimmering 2.35 ERA. The Dodgers picked him up in the 2013 draft's second round, and he's been zooming up charts ever since. As a starter, he's a couple of years away, but should the team take a bullpen route with him, he could be fast-tracked to MLB in the near future.
