2014 MLB Draft Previews: College Pitchers, Prep Pitchers, College Hitters, Prep Hitters

After the rank, name, position and school for each player, I list their age on draft day (June 6th), their height/weight and bats/throws. This is my ranking of the players eligible for the 2013 MLB Draft after spending the last year talking to scouts and industry insiders about the draft class.

1. Mark Appel, RHP, Stanford

Draft Day Age: 21.89, R/R, 6'5/215

The 6'5 righty flashes three knockout pitches (93-96 mph fastball that hits 98, slider, changeup) that all rate at least a 60 (on the 20-80 scouting scale) and flash 70 at their best. Appel made the adjustment this season to be more aggressive and has drawn the gaudy strikeout numbers his plus stuff didn't draw last season. He lacks the top shelf athleticism to have the command and consistency to project as a true ace, but he's clearly my top prospect and a potential frontline starter in short order.

2. Jonathan Gray, RHP, Oklahoma

Draft Day Age: 21.59, R/R, 6'4/240

The husky 6'4 righty took a big step forward this season, most notably with his velocity, going from sitting in the low to mid 90's in 2012 and early this season to not throwing any fastballs under 95 mph in full 100 pitch outings and hitting 100 mph often. He backs up his 80 fastball with a plus slider and solid changeup that's above average at times. Gray's arm action, delivery and command could are all a notch behind Appel and Gray's value is heavily tied to his velocity, which may wane in the coming years with two fewer days rest in between starts in pro ball.

3. Clint Frazier, CF, Loganville HS (GA)

Draft Day Age: 18.75, R/R, 6'0/190, College: Georgia

Frazier has the rare tools combination of plus-plus bat speed, plus raw power, plus foot speed and at least plus arm strength in a compact, mature 6'0, 190 pound frame. His Popeye forearms and electric tools aren't normally seen from smaller high school players that lack projection, and certainly not from a player with a flowing shock of red hair. Frazier simply doesn't have many player comparables and his uniqueness scares some scouts away from taking him in the top five, when you can't point to a similar player that's succeeded since there aren't really any comparables of any kind.

4. Kris Bryant, RF, San Diego

Draft Day Age: 21.42, R/R, 6'5/215

Bryant was a high profile tough sign out of high school that's really blossomed in his junior season. He will go out as a third baseman and could play center field now as he's an above average runner underway but either way he'll ultimately lose a step and fit in right field, where his plus arm fits nicely. Some scouts comparing the 6'5 slugger and his easy plus to plus-plus raw power to Nationals' OF Jayson Werth. Bryant's historic junior season (.346/.506/.880, 28 HR) is helping quiet concerns that his long arms could lead to only having a 50 or 55 hit tool (.260 to .270 batting average) in the big leagues.

5. Colin Moran, 3B, North Carolina

Draft Day Age: 20.68, L/R, 6'4/220

Late-developing New York-born 6'4 athlete has made progress defensively to allow him to stick at the hot corner professionally with sure hands, short-area quickness and 55 arm strength. His consistent lefty contact stroke (.385/.516/.646, 13 HR, 50 BB, 13 K) makes him an elite prospect while his average raw power projection keeps his ultimate upside lower than those ranked ahead of him and many of those ranked behind him.

6. Kohl Stewart, RHP, St. Pius X HS (TX)

Draft Day Age: 18.66, R/R, 6'3/195, College: Texas A&M (FB)

6'3 smooth athlete has scholarship to play QB at Texas A&M and has frontline starter potential as righty that's been up to 97 mph with plus slider. He has understandable rawness in his delivery due to lack of experience on the mound but shows feel for a changeup and scouts are confident in his ability to handle coaching.

7. Braden Shipley, RHP, Nevada

Draft Day Age: 21.29, R/R, 6'2/170

Cousin of NFL wideout Jordan Shipley is top-notch athlete and the recently-converted infielder that flashes number two starter potential. He sits 92-95 and has dialed his fastball up to 97 mph this spring with an out-pitch changeup that flashes a 65 potential. His number haven't been quite as good as the stuff as he has some rawness to his delivery and command and also is still refining and working a curveball that's above average at times into his repertoire.

8. D.J. Peterson, 1B, New Mexico

Draft Day Age: 21.43, R/R, 6'1/190

College third baseman will move across the diamond eventually as a pro but Billy Butler and Jeff Bagwell's names come up as the stout, 6'1 right-handed hitting slugger is an above average athlete with at least plus raw power, great feel to hit and the gaudy numbers this spring to prove it (.408/.522/.832, 16 HR).

9. Reese McGuire, C, Kentwood HS (WA)

Draft Day Age: 18.26, L/R, 6'1/190, College: San Diego

Smooth cold weather prep athlete offers ideal catcher's frame, plus arm, true catching actions, advanced lefty swing and rare feel to hit any kind of pitch. His things keeping him from being a top five pick is his fringy raw power, limited AB's this spring given the weather in Washington and the very checkered track record of 1st round prep catchers.

10. Dominic Smith, 1B, Serra HS (CA)

Draft Day Age: 17.98, L/L, 6'1/200, College: USC

It's rare to see a 6'1 high school first baseman without elite raw power to be ranked this high, but it's a weak draft class at the top and Smith has advanced feel to hit and bat control from a silky smooth swing with above average bat speed and all fields power that could produce 20 homers annually in the big leagues. He has an enticing package of attributes: he'll be 17 on draft day, has a long track record of performance, a plus arm (up to 93 on the mound from the left side) that would fit in right field except that he's a potential Gold Glover at first base. The broad set of skills and polish makes Smith arguably the safest bet in the prep class to reach the big leagues.

11. Austin Meadows, CF, Grayson HS (GA)

Draft Day Age: 18.09, L/L, 6'3/220, College: Clemson

Very well-known prospect has been picked apart this spring as hitting mechanics haven't improved and his fringy arm and 20 pounds he's added since showcase season may move him to left field eventually as a pro, though he has the defensive instincts to have a chance to stick in center field. He catches your eye with his above average tools, feel for the game and a pretty swing that flashes some power, but he was overrated entering the spring as a potential #1 overall pick.

12. Hunter Renfroe, RF, Mississippi State

Draft Day Age: 21.36, R/R, 6'2/210

Renfroe was raw athlete that added significant polish this year as his above average speed and glove combined with his plus arm and raw power to produce huge numbers in the SEC (.390/.484/.750, 15 HR). He's grown into his body after finally getting a few years to play baseball year-round against top competition after Renfroe was a multi-sport standout that didn't hit the showcase circuit very hard from a small Mississippi high school. This spring, he added his bat as his fifth and final above average tool by learning to lay off the breaking ball in the dirt, unlocking the above average bat speed and bat control that his plate discipline was obscuring.

13. J.P. Crawford, SS, Lakewood HS (CA)

Draft Day Age: 18.40, L/R, 6'2/180, College: USC

Not a surprise that J.P. is a cousin of Dodgers OF Carl Crawford as the lanky 6'2 shortstop is a big time athlete that can stick at short with silky smooth actions and above average hands and arm strength. Crawford is no slouch at the plate with feel to hit from the left side and projectable power, but he needs to make some mechanical adjustments to unlock his offensive potential, like lowering his hand position when he loads them.

14. Trey Ball, LHP, New Castle HS (IN)

Draft Day Age: 18.94, L/L, 6'6/180, College: Texas

6'6, 180 pound lefty is ultra-projectable, sitting 90-92, hitting 94 mph with more to come to his three above average pitches. He's a great athlete who is a top couple rounds prospect as a hitter, but clearly superior on the mound. Scouts love to dream on projectable, late-developing cold-weather athletes like Ball and there's rumors multiple teams are very interested in the top 10 picks.

15. Sean Manaea, LHP, Indiana State

Draft Day Age: 21.35, L/L, 6'5/215

The athletic 6'5 lefty had a coming-out party when he consistently sat 93-95 and hit 98 mph on the Cape, making him a favorite to go #1 overall entering the spring. He has been working 90-93 much of the season and was dropping off into the mid-80's a few innings into some recent starts. New mechanics, a recent hip injury, a heavy 2012 workload (157.2 IP) and bad luck are all to blame, but the multi-million dollar question is if the ace-level stuff ever returns.

16. Chris Anderson, RHP, Jacksonville

Draft Day Age: 20.85, R/R, 6'4/220

The late-developing Minnesota-born righty grew into 6'4, 220 pound frame this spring just like Wisconsin-born teammate RF Adam Walker did in 2012 before going to the Twins in the third round last year. Anderson hit 96 mph with plus slider early in the spring and looked like top 10 pick until his stuff backed up after overuse on poor team (17-34 record) where he's the only real pro prospect. He showed a potential 55 changeup and solid average command at his best, which was good enough in this draft to still comfortably land him in round one.

17. Austin Wilson, RF, Stanford

Draft Day Age: 21.33, R/R, 6'5/245

Wilson was a high profile prospect out of an LA-area high school and turned down seven figures from St. Louis. He's had an up-and-down college career, battling with his approach at the plate and mechanics, like many Stanford hitters before him due to the opposite field ground ball focused swings they encourage. Wilson has the raw tools to sneak into the top 10 picks this year: easy plus raw power and arm strength, average speed, above average bat speed and defensive instincts are all the elements to becomes an above average regular. Scouts have seen him play like a smaller human often but there is a built-in excuse to fly him up the board due to the Stanford Swing and he's been solid in 2013 after returning from an early elbow injury.

18. Ryne Stanek, RHP, Arkansas

Draft Day Age: 21.86, R/R, 6'4/190

Unsigned as third round pick out of Kansas high school, Stanek has been high profile, successful and flashing plus stuff since he got to Arkansas. That's mysteriously not been the case this season as, in the past few weeks, his former plus to plus-plus slider has been average and his body language has been terrible. His average changeup and command were always a weak points but have also regressed this spring and with his velocity down a tick or two late in the season (92-94 hitting 95 mph) he looks more like an innings eater than a frontline starter. There are rumors a couple teams think this is a great buy low opportunity and still have him securely in the top half of the first round.

19. Nick Ciuffo, C, Lexington HS (SC)

Draft Day Age: 18.25, L/R, 6'1/210, College: South Carolina

Ciuffo committed to the Gamecocks as a high school freshman, has been a known quantity to scouts for years, and is one of the more consistent players in the class. He's a vocal leader with a plus arm that is athletic enough with solid actions to stick behind the plate long-term. He also has above average raw power and flashes enough bat speed and bat control to get to that power in games.

20. Tim Anderson, SS, East Central CC (MS)

Draft Day Age: 19.95, R/R, 6'1/180, College: UAB

Anderson was an unknown Juco hoops player last season that came out late for baseball, was hidden in left field and went undrafted. This year he's a lock to go in the top 50 picks with multiple clubs in the first round in heavy on one of the three possible everyday shortstops in the class. He's performed well this year despite understandably needing some polish to his dynamic quick-twitch athleticism. The tools are for real: plus-plus speed, potential average raw power that already shows up in games and to the opposite field, plus bat speed, above average arm strength and true shortstop actions.

21. Hunter Harvey, RHP, Bandys HS (NC)

Draft Day Age: 18.49, R/R, 6'4/185, College: None

Son of former MLB reliever Bryan Harvey is perceived as easy sign due to a lack of a college commitment, so he'll likely go higher than this to a budget conscious club or one that wants to save money to chase signability types later in the draft. Harvey's delivery is a even more raw than Kohl Stewart and Harvey is a similar but slightly less great athlete, but Harvey is still physically immature and doesn't show as much feel. Harvey's stuff, at it's best, is in the same ballpark as Stewart: up to 97 at times, flashing a plus curveball and usable changeup.

22. Jon Denney, C, Yukon HS (OK)

Draft Day Age: 18.69, R/R, 6'2/205, College: Arkansas

Denney burst onto the scene in last year's Area Code games with some tape measure shots: his plus raw power is among the best in the class and he hits enough for it to show up in games all summer. He's had an up-and-down spring and needs more work behind the plate, but the raw tools are there to be a good receiver and his plus arm is another standout tool.

23. Josh Hart, CF, Parkview HS (GA)

Draft Day Age: 18.68, L/L, 6'1/190, College: Georgia Tech

Well-known prospect from powerhouse Atlanta-area program (produced Royals RF Jeff Francoeur & 2012 A's 1st rounder 1B Matt Olson) with long track record of hitting and has matured to develop some gap power to go with plus-plus speed, above average arm and advanced glove. The bat speed and feel for hitting is real, drawing Kenny Lofton comparisons, but Hart's mechanics have gone backwards this spring. He gets too upright with an all arms swing, which appears fixable and hasn't affected his performance much due to his big talent, but it may possibly slide him into the early second round.

24. Alex Balog, RHP, San Francisco

Draft Day Age: 20.89, R/R, 6'6/225

Big righty had some buzz entering the spring before showing average stuff and spotty command. With the pressure odd, Balog bounced back in a big way late in the spring, sitting 92-94 and hitting 96 mph regularly. He flashes a plus slider and curveball with an improving changeup that is also above average at times. Scouts have passed along that the Phillies are among the most interested clubs, potential in the middle of the first round.

25. Alex Gonzalez, RHP, Oral Roberts

Draft Day Age: 21.39, R/R, 6'3/200

Gonzalez has slowly gained momentum after showing 91-94 fastball that hit 95 mph and a 84-87 mph slider that flashed plus on the Cape. The life on his fastball, bite to his slider and command to both sides of the plate have progressed this spring and "Chi Chi" is looking like a good bet to become a mid-rotation starter that has a good chance to slide into the back of round one.

26. Phil Bickford, RHP, Oaks Christian HS (CA)

Draft Day Age: 17.91, R/R, 6'4/200, College: Cal State Fullerton

Bickford was a generic projection righty entering the spring, then all of a sudden the projection started showing up when he hit 97 mph in March. He's still got a lot of room to fill out and sits in the low-to-mid-90's with an above average breaking ball but has more current feel for his delivery than Hunter Harvey, flashing solid average command and a usable changeup.

27. Rob Kaminsky, LHP, St. Joseph HS (NJ)

Draft Day Age: 18.76, B/L, 6'0/190, College: North Carolina

Smallish lefty also gives away some plane with drop-and-drive delivery but has feel for pitching and an average changeup in support of at times dominating fastball-curveball combo. Kaminsky will sit 89-93, has hit 95 mph a number of times this spring with a devastating plus to plus-plus low 80's hammer curveball and makeup that scouts rave about.

28. Eric Jagielo, 3B, Notre Dame

Draft Day Age: 21.05, L/R, 6'3/215

Jagielo likely ends up at first base eventually, where his plus lefty power would still profile, but some scouts give him a chance to stick at third base as he's a solid athlete still new to the position, though he'll never be more than average. He has enough hitting ability to get to his power in games and has had a big spring for the Irish (.386/.502/.639, 8 HR).

29. Aaron Judge, RF, Fresno State

Draft Day Age: 21.11, R/R, 6'7/255

Massive athlete's frame has been compared to Blake Griffin and LeBron James with tools that remind you of Giancarlo Stanton. Problem is Judge's length creates swing-and-miss and may keep him from ever tapping into his plus-plus raw power in big league games at an age when Stanton already had over 30 big league homers. Judge also draws attention as an above average underway runner with a plus arm and more feel at the plate than anyone this size has ever had.

30. Oscar Mercado, SS, Gaither HS (FL)

Draft Day Age: 18.47, R/R, 6'2/175, College: Florida State

Slick-fielding shortstop with contact stroke from the right side was well-known and projected first rounder before awful spring filled with lazy flyouts and careless errors. The everyday big league shortstop tools and projection are still there, but scouts are less excited about how much he might improve now.

31. Andrew Thurman, RHP, UC Irvine

Draft Day Age: 21.49, R/R, 6'3/205

Thurman was a crafty righty with four pitches over the summer that started hitting 95 mph at the tail end of his Cape stay and carried it over to this spring. His above average stuff, smooth motion and advanced feel could be a league average or slightly better starter in the big leagues.

32. Marco Gonzales, LHP, Gonzaga

Draft Day Age: 21.31, L/L, 6'1/185

Athletic, smaller lefty has above average command and out-pitch changeup to carry his 88-92 mph fastball and average curveball. Big numbers this year and potential quick-moving innings eater that also has a solid lefty swing but is a far superior pitching prospect.

33. Billy McKinney, CF, Plano West HS (TX)

Draft Day Age: 18.79, L/L, 6'1/195, College: TCU

Has hit everywhere he's been but isn't a burner, though compact athlete has a chance to stick in center field. Doesn't have standout raw power and bars (locks) his front elbow often but is athletic enough in the box to make it work. McKinney is a pure prep hit tool bet that's a smaller version of Austin Meadows.

34. Phil Ervin, RF, Samford

Draft Day Age: 20.89, R/R, 5'10/205

Had coming out party on the Cape and will flash five above average tools at times but frame and smaller strides may limit to right field, he's had a bum ankle most of the spring and his swing can get a little uphill which is more of an issue in a corner.

35. Ian Clarkin, LHP, Madison HS (CA)

Draft Day Age: 18.31, L/L, 6'2/190, College: San Diego

Clarkin is another well-known performer with a track record that works 89-92 and hits 94 mph with a fastball that will vary a tick or two outing to outing. His curveball with flash plus and his changeup is above average at times but the command and consistency are issues and there isn't a ton of projection.

36. Connor Jones, RHP, Great Bridge HS (VA)

Draft Day Age: 18.66, R/R, 6'3/190, College: Virginia

He sat 89-92 with good command over summer/fall and started hitting 95 mph regularly this season with heavy fastball and above average to plus changeup. Average slider has also progressed and Jones has first round buzz along with rumors of having a high signability number.

37. Jason Hursh, RHP, Oklahoma State

Draft Day Age: 21.68, R/R, 6'2/200

Smaller righty is fresh off Tommy John surgery, but has been up to 98 mph this spring with heavy fastball and smooth delivery, though off-speed is average as feel slowly returns.

38. Aaron Blair, RHP, Marshall

Draft Day Age: 21.03, R/R, 6'5/220

Steady performer will flash three above average pitches and hit 96 mph early in the spring, up a few ticks from a solid Cape showing.

39. Tucker Neuhaus, 3B, Wharton HS (FL)

Draft Day Age: 17.97, L/R, 6'3/190, College: Louisville

Has only played a handful of games this spring due to multiple injuries but is healthy now and has above average lefty power with more to come, has average or better defensive projection at the hot corner is a hot commodity for pre-draft workouts

40. Ryan Boldt, CF, Red Wing HS (MN)

Draft Day Age: 18.54, L/R, 6'1/190, College: Nebraska

Dynamic tools similar to Josh Hart have been held off the field all spring due to bad Minnesota weather and knee injury. There will be at least one club that will offer seven figures on strength of summer/fall performance.

41. Andrew Mitchell, RHP, TCU

Draft Day Age: 21.58, R/R, 6'3/220

The power righty started most of his career as a Horned Frog but was moved to relief to start this season. He didn't get many chances to pitch in high leverage situations as planned, so he was moved back to the rotation midway through the season and scouts are still split on whether he's a starter or reliever long-term. In relief, I've seen Mitchell sit 93-95 and hit 97 mph with an above average to plus curveball and a changeup that flashes above average, so the raw stuff is there to be a closer. He has an arm-heavy delivery that negatively impacts his command in longer outings, so that combined with a tick or two less velocity (sits 90-93, hitting 95 mph) makes relief seem more likely, but he'll get every chance to stick as starter first.

42. Jake Brentz, LHP, Parkway South HS (MO)

Draft Day Age: 18.73, L/L, 6'2/190, College: Missouri

Very athletic lefty is new to pitching and has been up to 97 mph this spring with slider that flashes plus and changeup and curveball that are above average at times. He lacks projection and polish with command that totally deserts him at times and his velocity is more often 90-93 mph but he's just scratching the surface.

43. Kyle Serrano, RHP, Farragut HS (TN)

Draft Day Age: 17.92, R/R, 6'1/185, College: Tennessee

Son of the Volunteers head baseball coach shows polished feel for pitching and delivery at young age for powerhouse prep program but size limits his projection. He'll hit 95 mph and sits in the low 90's with some life, a plus, hard curveball and inconsistent changeup that flashes above average.

44. Ryan Eades, RHP, LSU

Draft Day Age: 21.48, B/R, 6'3/200

Inconsistent power righty will flash above average to plus fastball and slider with solid average changeup, but stuff can get flat and he's hit more often than he should be.

45. Jonathon Crawford, RHP, Florida

Draft Day Age: 21.60, R/R, 6'1/205

Had top 10 pick buzz after hitting 99 mph with a 65 slider on the 20-80 scouting scale late in 2012 but scouts were always skeptical of the velo spike (88-91 in high school) from smaller righty with a rigid delivery and no projection. The stuff backed up some this spring, working 90-93 and hitting 95 mph with an above average slider that only occasionally flashes plus. His changeup is above average at times, so it'll be hard for Crawford to slide out of the top 50 picks, but he may be headed in the wrong direction.

46. Riley Unroe, 2B, Desert Ridge HS (AZ)

Draft Day Age: 17.84, B/R, 6'0/180, College: USC

Super athletic prep shortstop with big league father flashes plus speed, hands for the infield, average raw power and feel to hit from both sides. He likely fits at second base or center field long term, has some rawness to his game and there's rumors he won't be easy sign, but Unroe has sparked a lot of interest in the top 50 picks.

47. Matt Krook, LHP, St. Ignatius HS (CA)

Draft Day Age: 18.63, L/L, 6'4/195, College: Oregon

Lefty was 88-91 with command issues entering spring, then hit 95 mph with a curveball that flashed plus in his first outing. His stuff and command hves been all over the place this spring but his arm action, projectable frame and top shelf fastball-curveball flashes should be enough to meet what should is rumored to be a $1.5 million asking price.

48. Hunter Dozier, 3B, Stephen F. Austin

Draft Day Age: 21.79, R/R, 6'4/210

Small school shortstop has already outgrown position but can stick long-term at third base and has sound swing, above average raw power and huge numbers against lesser competition.

49. Chad Pinder, 3B, Virginia Tech

Draft Day Age: 21.19, R/R, 6'2/195

College third baseman is good defender that may fit best at second base until he fills out his frame. You can project average raw power and he shows the elements to be an above average bat.

50. Chris Okey, C, Eustis HS (FL)

Draft Day Age: 18.44, R/R, 6'0/175, College: Clemson

Steady defender behind the plate with a plus arm and an athletic, compact frame is a rare solid-average runner as catcher. Okey has a track record of hitting despite timing issues in his mechanics this spring that have led to struggles. He has good bat speed and feel to hit but his raw power is below average, though scouts have seen him wear out the gaps against good pitching.
