Top 40 Twins Prospects of 2014: 10, 9, 8, 7, 6

Also in this series: 11-15, 16-20, 21-25, 26-30, 31-35, 36-40.

10. Ryan Eades | Starter | DOB: 12/91 | Throws: Right | Draft: 2013-2

YEAR     LV      G     GS      ERA        IP       H     HR      SO     BB
2013     RK+    10      0     4.60      15.2      13      0      13     12

As a college starter with three seasons of major conference experience LSU right-hander Ryan Eades was a prototypical Twins target in the second round of June's draft and he's the eighth college pitcher they've selected with a top-50 pick since 2005. Eades missed his senior season of high school following shoulder surgery, but was injury free at LSU and led the team in starts last season.

However, fading down the stretch in 2012 and 2013 put his durability in some question and Eades struggled in his pro debut with 12 walks in 16 innings at rookie-ball. Even after a late-season fade Eades finished with a 2.81 ERA for one of the country's best college teams, but a .269 opponents' batting average and 77 strikeouts in 96 innings were underwhelming. And that modest strikeout rate is actually an improvement over 2012, when Eades struck out just 63 in 94 innings.

Combined during his final two years Eades averaged 6.6 strikeouts per nine innings, which paled in comparison to LSU's aces Kevin Gausman and Aaron Nola. Eades obviously isn't on the same level as Gausman and Nola or he wouldn't have been available at No. 43, but the point is that his raw stuff has yet to turn into strikeouts. With that said, it's good raw stuff. Baseball America rated him 37th in the draft class, noting that Eades "looks the part of a frontline starter."

9. Trevor May | Starter | DOB: 9/89 | Throws: Right | Trade: Phillies

YEAR     LV      G     GS      ERA        IP       H     HR      SO     BB
2011     A+     27     27     3.63     151.1     121      8     208     67
2012     AA     28     28     4.87     149.2     139     22     151     78
2013     AA     27     27     4.51     151.2     149     14     159     67

Acquired from the Phillies last winter in the Ben Revere trade, Trevor May repeated Double-A as a 23-year-old and showed little improvement across the board. He posted a 4.51 ERA compared to the Eastern League average of 4.01, cut his walk rate only marginally to a still-awful 4.0 per nine innings, and induced fewer ground balls than his first go-around to signal that a dip in home runs allowed may not be as encouraging as it first appears.

The good news is that the 6-foot-5 right-hander still throws very hard and still misses plenty of bats, striking out 9.4 per nine innings after whiffing 9.1 per nine innings in 2012. Those strikeout rates are good rather than great and can't compare to May's eye-popping strikeout totals in the low minors, but clearly the former fourth-round pick still has some upside. However, he's no longer considered a high-end prospect after cracking Baseball America's top-100 list for 2012.

At the time of the trade there were rumblings about May being destined for relief work long term and the lack of progress he's made, particularly with his control, have raised the volume on those concerns. He likely needs to show considerable progress at Triple-A this year or risk being shifted to the bullpen, although certainly May could eventually still make a big impact as a late-inning reliever with a mid-90s fastball.

8. Jorge Polanco | Second Base | DOB: 7/93 | Bats: Switch | Sign: Dominican

YEAR     LV      PA      AVG      OBP      SLG     HR    XBH     BB     SO
2011     RK-    193     .250     .319     .349      1     12     15     24
2012     RK+    204     .318     .388     .514      5     22     20     26
2013     A-     523     .308     .362     .452      5     47     42     59

Signed out of the Dominican Republic for $775,000 as a 16-year-old the same year the Twins added Miguel Sano and Max Kepler as big-dollar international prospects, Jorge Polanco has likely outgrown shortstop and become a good defensive second baseman with a potentially very strong bat for the position. Polanco showed a ton of improvement at rookie-ball in 2012 and then transitioned to full-season competition last year by thriving at low Single-A as a 19-year-old.

Polanco hit .308 with just 59 strikeouts in 523 plate appearances, drew a decent number of walks, and smacked 47 extra-base hits, all while being one of only nine teenagers in the entire Midwest League to play at least 100 games. As a switch-hitter he fared equally well versus righties and lefties while posting an OPS above .765 in all five months of the season and managers voted him the best defensive second baseman in the league.

He'll likely play most and perhaps all of this season as a 20-year-old at high Single-A. To put that in some context, consider that no one under 21 logged 500 plate appearances in the Florida State League last season and only three logged more than 400. Simply holding his own in the FSL would be an accomplishment and if Polanco produces in 2014 like he did in 2013 he'll be near the top of this list next spring.

7. Josmil Pinto | Catcher | DOB: 3/89 | Bats: Right | Sign: Venezuela

YEAR     LV      PA      AVG      OBP      SLG     HR    XBH     BB     SO
2011     A+     236     .262     .305     .389      5     17     12     36
2012     A+     393     .295     .361     .473     12     36     39     63
         AA      52     .298     .365     .553      2      7      4     10
2013     AA     453     .308     .411     .482     14     38     64     71
        AAA      75     .314     .333     .486      1     10      2     12
        MLB      83     .342     .398     .566      4      9      6     22

Well, we know Josmil Pinto can hit. Last season he followed up a strong 2012 between high Single-A and Double-A by hitting .308/.411/.482 with nearly as many walks as strikeouts in 107 games at Double-A, batting .314 with 10 extra-base hits in a 19-game Triple-A stint, and making his Twins debut by hitting .342/.398/.566 in 21 games as a September call-up. Add it all up and Pinto batted .314 with 19 homers, 37 doubles, and 72 walks in 147 games as a 24-year-old.

And yet there are questions about how he fits into the long-term plans because his defense behind the plate has always received mixed reviews and the Twins thought so little of his ability to catch in the majors this season that they signed Kurt Suzuki to be the starter despite his not cracking a .700 OPS since 2009. As a poor but passable catcher Pinto has enough bat to be an impact player, but as a designated hitter his bat would be nothing special unless he adds more power.

Last season MLB catchers hit .245/.310/.388 for a .688 OPS that was the second-worst from any position behind only shortstop. By comparison DHs posted a .725 OPS that was either ahead or within 10 points of every position except first base and right field. Beyond that, on the Twins his long-term path would be relatively clear at catcher, whereas there are always plenty of DH options and specifically Miguel Sano or Oswaldo Arcia may wind up as preferred choices there.

6. Eddie Rosario | Second Base | DOB: 9/91 | Bats: Left | Draft: 2010-4

YEAR     LV      PA      AVG      OBP      SLG     HR    XBH     BB     SO
2011     RK+    298     .337     .397     .670     21     39     27     60
2012     A-     429     .296     .345     .490     12     48     31     69
2013     A+     231     .329     .377     .527      6     24     17     29
         AA     313     .284     .330     .412      4     26     21     67

Eddie Rosario had a very nice 2013, beginning the year by crushing high Single-A pitching and finishing it by holding his own at Double-A as a 21-year-old, but then he began 2014 by receiving a 50-game suspension for a "drug of abuse." Under the terms of the minor league drug agreement that means he previously tested positive without getting a suspension and then continued to use the drug, which is perhaps more troubling behavior than the drug use itself.

On the field Rosario did what he's done since the Twins made him their fourth-round draft pick out of Puerto Rico in 2010, hitting for a high batting average with gap power and poor plate discipline. He also spent the entire season at second base after beginning the transition from outfielder to infielder in 2012, but there are questions about his ability to be a serviceable defender there in the majors and his offensive skill set would look somewhat marginal for a corner outfielder.

Rosario is a career .307 hitter, including at least .290 in all four seasons, but he's totaled just 22 homers in 217 games above rookie-ball while walking just 69 times compared to 165 strikeouts. That includes a 67/21 K/BB ratio in 70 games at Double-A, although in fairness he was one of only nine 21-and-under hitters in the Eastern League. Still, it doesn't look like he'll produce a ton of homers or walks, which is a profile that typically doesn't equal a big impact in an outfield corner.

15. Travis Harrison | Third Base | DOB: 10/92 | Bats: Right | Draft: 2011-1

YEAR     LV      PA      AVG      OBP      SLG     HR    XBH     BB     SO
2012     RK+    253     .301     .383     .461      5     21     24     51
2013     A-     537     .253     .366     .416     15     43     68    125

Travis Harrison was selected by the Twins with the 50th pick in the 2011 draft as compensation for losing Orlando Hudson as a free agent and signed away from USC for $1.05 million. Touted as one of the best bats in the high school class, Harrison had an impressive debut at rookie-ball and then showed some of his flaws last year while moving up to full-season competition, hitting just .253 while striking out 125 times in 129 games.

Combined with his rookie-ball showing Harrison has 176 strikeouts in 189 games, which is a red flag in the low minors. Beyond that his power has been somewhat underwhelming after being billed as elite coming out of high school, with 20 homers and a .161 Isolated Power in 790 total plate appearances. That's certainly not a lack of power, especially considering Harrison played last season at age 20, but given questions about his ability to stick at third base he needs to mash.

One bright spot is that Harrison drew 68 walks last season and also got plunked by 14 pitches, which suggest he should be able to get on base at a decent clip even if all the strikeouts keep his batting average modest. Ultimately much of his value depends on where he ends up defensively and how much power he can develop by the time he reaches Minnesota. So far he's shown enough to be an intriguing prospect, but the edges are still pretty rough.

14. Danny Santana | Shortstop | DOB: 11/90 | Bats: Switch | Sign: Dominican

YEAR     LV      PA      AVG      OBP      SLG     HR    XBH     BB     SO
2011     A-     409     .247     .298     .373      7     27     25     98
2012     A+     547     .286     .329     .410      8     38     29     77
2013     AA     587     .297     .333     .386      2     34     24     94

Danny Santana is generally more highly thought of as a prospect than his performance in the minors would suggest based on the idea that athleticism, speed, and defense will eventually allow him to become a starting-caliber shortstop in the majors. At age 23 he still has an opportunity to develop further, but in the meantime he hasn't been all that impressive, making a lot of errors (for whatever that's worth) along with little power and awful strike zone control.

Last season he hit .297 at Double-A, but managed just two homers and 24 walks in 131 games on the way to a modest .333 on-base percentage and .386 slugging percentage. His numbers at high Single-A in 2012 were similar and combined during the past two seasons he totaled 10 homers in 1,134 plate appearances, struck out 171 times versus 53 walks, and was successful on just 66 percent of his steal attempts. Right now he projects as a sub par offensive player.

The good news is that Santana is still pretty young and the bar for offense at shortstop is very low, so even hitting, say, .275 with minimal power and a poor walk rate would make him a solid all-around player if his glove is a huge asset. If instead his defense at shortstop is merely decent, then his current offensive skill set leaves Santana looking like something less than a building block, even considering the Twins' longstanding inability to develop competent middle infielders.

13. Max Kepler | First Base | DOB: 2/93 | Bats: Left | Sign: Germany

YEAR     LV      PA      AVG      OBP      SLG     HR    XBH     BB     SO
2011     RK+    221     .262     .347     .366      1     15     23     54
2012     RK+    269     .297     .387     .539     10     31     27     33
2013     A-     263     .237     .312     .424      9     23     24     43

When the Twins signed Max Kepler out of Germany for $800,000 in 2009 he oozed potential. At age 16 he was still growing into a 6-foot-4 frame and had uncommon athleticism along with the unique background of parents who met while performing in the ballet. He was seen as a potential center fielder long term and performed well in the low minors, but Kepler took a step backward last season and has lost a lot of upside as he's matured physically.

He played primarily first base at low Single-A last season, in part because of an elbow injury that delayed this 2013 debut and in part because he no longer has the speed to handle center field on a regular basis. Going from center field to first base or an outfield corner puts far more pressure on the development of Kepler's bat and he hit .237 with a high strikeout rate last year. However, he also showed solid power and patience with nine homers and 24 walks in 61 games.

Kepler is still just 21 years old and still has considerable potential, but his upside has shrunk dramatically. At this point he needs to stay healthy and put up some big numbers offensively to re-emerge as a top prospect, as he's yet to play more than 61 games in a season and yet to advance past low Single-A. If the power arrives Kepler could reach Double-A this year and work his way into the Twins' plans for 2015, but for now he's a question mark.

12. Michael Tonkin | Reliever | DOB: 11/89 | Throws: Right | Draft: 2008-30

YEAR     LV      G     GS      ERA        IP       H     HR      SO     BB
2011     A-     48      3     3.87      76.2      82      3      69     24
2012     A-     22      0     1.38      39.0      29      1      53      9
         A+     22      0     2.97      30.1      24      2      44     11
2013     AA     22      0     2.22      24.1      21      0      30      8
         AAA    30      0     4.41      32.2      33      3      36      8
         MLB     9      0     0.79      11.1       9      0      10      3

Michael Tonkin was a 30th-round pick out of high school in 2008 and looked like a mediocre starter prospect in the low minors, but Jason Kubel's brother-in-law has emerged as a potential impact arm since switching to the bullpen full time in 2011. Tonkin stands 6-foot-7 with a mid-90s fastball and has racked up 242 strikeouts in 213 innings during the past three seasons, including an impressive nine-appearance debut with the Twins.

And unlike a lot of hard-throwing young arms Tonkin has also shown good control with a career walk rate of 2.4 per nine innings and just 19 walks in 68 innings last season while rising from Double-A to the majors as a 23-year-old. He's huge, he throws a very hard fastball-slider combo, he misses lots of bats, and he actually knows where the ball is going most of the time, which is the most reliable recipe for a good relief prospect.

Bullpen depth is one of the Twins' few strengths at this point, making it unclear how early Tonkin could be in the big-league relief mix this season, but he certainly looks MLB-ready and projects as a potential late-inning setup man for Glen Perkins. As a reliever in a stacked farm system Tonkin is often overlooked, but in terms of the ability to make an immediate impact few Twins prospects are better.

11. Lewis Thorpe | Starter | DOB: 12/95 | Throws: Left | Sign: Australia

YEAR     LV      G     GS      ERA        IP       H     HR      SO     BB
2013     RK-    12      8     2.05      44.0      32      2      64      6

Investing baseball's most resources into scouting Australia has yet to pay huge dividends for the Twins, producing a handful of marginal big leaguers and Grant Balfour, who starred elsewhere. Lewis Thorpe has a chance to change that after signing for $500,000 as a 16-year-old in 2012 and dominating rookie-ball in his pro debut last season, posting a 2.05 ERA and 64/6 K/BB ratio in 44 innings against Gulf Coast League hitters.

At age 18 he works in the low-90s and tops out in the mid-90s, complementing his fastball with a changeup that draws praise, and the extent to which he sliced up opponents last season suggests he's ready to skip a level of rookie-ball and go directly to low Single-A. Thorpe is the youngest of my top 20 prospects and if you want to feel really old consider that he was born six months after the Twins drafted Doug Mientkiewicz, so he's a long way from the big leagues.

In terms of long-term upside, however, few prospects in the Twins' farm system can compete with the 6-foot-2 left-hander and he has more polish than most rookie-ball pitchers. His place on this list reflects how I'm generally conservative when it comes to rankings prospects--and particularly pitchers--who've yet to face full-season competition, but Thorpe has cracked some prominent MLB-wide top-100 lists.

Top 40 Twins Prospects of 2014: 20, 19, 18, 17, 16

Also in this series: 21-25, 26-30, 31-35, 36-40.

20. Stephen Gonsalves | Starter | DOB: 7/94 | Throws: Left | Draft: 2013-4

YEAR     LV      G     GS      ERA        IP       H     HR      SO     BB
2013     RK-     5      2     0.63      14.1       8      0      18      7
         RK+     3      3     1.29      14.0      10      0      21      4

After selecting Kohl Stewart with the fifth overall pick in last year's draft the Twins used their fourth-round pick on another high school pitcher in California left-hander Stephen Gonsalves. Baseball America's pre-draft scouting report noted that he "entered the spring as a potential first-round pick, but his stock has fallen as scouts have been disappointed with his inconsistent velocity and command."

Gonsalves signed for $700,000--which is $150,000 more than third-rounder Stuart Turner and $320,000 more than fifth-rounder Aaron Slegers--and had a very impressive pro debut, posting a 0.95 ERA and 39 strikeouts in 28 innings split between two levels of rookie-ball. Gonsalves is 6-foot-5 with a low-90s fastball and developing curveball, which along with the strong debut suggests plenty of long-term upside.

He won't be 20 years old until July, so the Twins figure to take things very slow with Gonsalves and even if everything goes according to plan he likely won't enter into their big-league plans for another few years. He'll probably spend most of this season at low Single-A, perhaps with a workload limit, and one thing to watch is whether he can continue to miss a ton of bats while showing decent control.

19. Tyler Jones | Reliever | DOB: 9/89 | Throws: Right | Draft: 2011-11

YEAR     LV      G     GS      ERA        IP       H     HR      SO     BB
2012     A-     18     16     4.67      86.2      90      5     102     35
2013     A-     24      0     1.93      37.1      19      0      44     16
         A+     12      0     4.20      15.0      18      0      22      4

Tyler Jones wasn't particularly good as a starter at LSU, but the Twins liked his mid-90s fastball enough to take him in the 11th round of the 2011 draft. He had a rough pro debut at rookie-ball after signing for $105,000 and then posted a 4.67 ERA at low Single-A in 2012, which caused the Twins to move him from the rotation to the bullpen last year. Jones thrived as a reliever, striking out 66 batters in 52 innings while holding opponents to a .196 batting average and zero homers.

Jones is already 24 years old and has yet to pitch an inning above Single-A, but he should move fairly quickly now that he's a full-time reliever. And even while struggling overall as a starter in 2012 he missed a ton of bats, striking out 102 batters in 87 innings. He also has the raw stuff to match, complementing a mid-90s fastball with a hard slider and throwing it all from a 6-foot-4, 250-pound frame. In other words, he has late-inning potential.

For that to happen, however, Jones will need to improve his control. He issued 3.6 walks per nine innings as a starter in 2012 and 3.4 walks per nine innings as a reliever last season, although he did show some strides down the stretch at high Single-A. He throws hard and he generates tons of strikeouts while inducing lots of ground balls and very few homers. Jones, Michael Tonkin, and Zack Jones give the Twins a trio of high-upside reliever prospects.

18. Adam Walker | Right Field | DOB: 10/91 | Bats: Right | Draft: 2012-3

YEAR     LV      PA      AVG      OBP      SLG     HR    XBH     BB     SO
2012     RK+    252     .250     .310     .496     14     25     19     76
2013     A-     553     .278     .319     .526     27     65     31    115

When the Twins drafted Adam Walker in the third round out of Jacksonville University in 2012 they touted his power potential and so far that skill has lived up to the hype. He has 41 homers in 187 career games, including 27 homers and 65 total extra-base hits in 129 games at low Single-A last season. Not only did he lead the entire Midwest League with 27 homers, no other hitter went deep even 20 times. He also led the league in total bases, slugging percentage, and RBIs.

So why isn't Walker much higher on this list? For one thing he posted those impressive power numbers as a 21-year-old with college experience spending a full season at low Single-A. That's not elderly, but age and level of competition are always important factors in evaluating prospects. Beyond that, Walker's plate discipline is terrible. He struck out 115 times compared to just 31 walks and his lack of strike-zone control has been a red flag dating back to college.

Elite power is a helluva skill to have and he's also a good athlete, but it's tough to get excited about a corner outfielder with a .316 on-base percentage and 191/50 K/BB ratio in the low minors. Walker had 184 strikeouts in 168 college games and 191 strikeouts through 187 games as a minor leaguer, and he's done all that whiffing with a swing-at-everything approach that hasn't led to a decent walk rate. He's intriguing, but a major adjustment will be needed at some point.

17. Niko Goodrum | Shortstop | DOB: 2/92 | Bats: Switch | Draft: 2010-2

YEAR     LV      PA      AVG      OBP      SLG     HR    XBH     BB     SO
2011     RK+    230     .275     .352     .382      2     15     21     56
2012     RK+    269     .242     .349     .419      4     24     38     56
2013     A-     455     .260     .364     .369      4     30     60    105

Niko Goodrum spent three seasons in rookie-ball after being the Twins' second-round draft pick out of a Georgia high school in 2010, finally moving up to full-season competition last year. He got off to a very nice start at low Single-A, hitting .270/.382/.388 with 31 walks in 48 games before a home plate collision on June 2 left him with a concussion. He returned two weeks later, but then went through an ugly 20-game stretch in which he hit .151 with 22 strikeouts.

Goodrum bounced back to hit .286/.379/.397 in his final 34 games and ended up ranking among the Midwest League's top 15 in walks and on-base percentage. That's impressive for a 21-year-old shortstop, but Goodrum's lack of power, relatively high strikeout rate, and career .246 batting average are all potential red flags for the switch-hitter offensively. And ultimately a huge portion of his long-term upside depends on whether he can remain at shortstop defensively.

He's big for a shortstop at 6-foot-4 and has made lots of errors so far, but that isn't necessarily indicative of anything negative and unlike several other one-time shortstop prospects the Twins haven't moved Goodrum off the position yet. He's also a good athlete, went 20-for-24 stealing bases last year, and has always gotten praise for a strong throwing arm. Goodrum's skill set is an interesting one with a lot to like, but the flaws are noticeable too.

16. Mason Melotakis | Starter | DOB: 6/91 | Throws: Left | Draft: 2012-2

YEAR     LV      G     GS      ERA        IP       H     HR      SO     BB
2012     RK+     7      0     1.35       6.2       2      0      10      2
         A-     13      0     2.08      17.1      15      3      24      4
2013     A-     24     18     3.16     111.0     106      6      84     39

Mason Melotakis starred as a reliever at Northwestern State, but like several of the other college relievers the Twins selected in the 2012 draft they gave him a chance to become a starter. So far it's gone fairly well for the second-round pick, as Melotakis transitioned to the rotation at low Single-A last season with a 3.16 ERA in 111 innings, allowing just six homers and actually faring slightly better versus righties than lefties despite being a southpaw.

However, his strikeout rate of 6.8 per nine innings wasn't impressive and even that was inflated by some late-season relief work. As a 22-year-old with college experience Melotakis was also old for the level of competition and after finishing the 2012 season in the Midwest League it's a little odd that the Twins let him spend all of 2013 there as well. His inexperience as a starter surely played a part in the lack of a rush to promote him, but now he's 23 heading to high Single-A.

This year should reveal a lot about whether Melotakis has a future as a starter and if he continues to fare well it'd be nice to see the Twins give him a midseason push up to Double-A. He works in the low-90s with his fastball and gets positive reviews on his slider, which is a combination that makes the bullpen a safe fallback option. Right now he looks like the best bet to ever be a full-time member of the Twins' rotation among all the college arms they drafted in 2012.

25. Stuart Turner | Catcher | DOB: 12/91 | Bats: Right | Draft: 2013-3

YEAR     LV      PA      AVG      OBP      SLG     HR    XBH     BB     SO
2013     RK+    142     .264     .340     .380      3      8     12     22

In the third round of last year's draft the Twins selected University of Mississippi catcher Stuart Turner, who had a reputation for being a good defender with an iffy bat despite hitting .374/.444/.518 in 62 games. Turner played just one season against top-flight competition, transferring to Ole Miss from a junior college, and Baseball America noted that "scouts don't like his swing and question his ability to sting the ball consistently."

There were no such questions behind the plate, as BA called Turner the best defensive catcher in the class who "combines strength at 6-foot-2, 220 pounds with flexibility, agile feet, and excellent arm strength." ESPN offered similar praise, calling Turner the draft's "best catch-and-throw guy" with "outstanding hands and a plus arm." All of which suggests that he'd project as a backup if the scouts are right to doubt his bat and a good all-around starter if the numbers prove them wrong.

The early returns weren't encouraging, as Turner began his pro career as a 21-year-old playing against rookie-ball competition in the Appalachian League and still hit just .260 with three homers in 34 games. That's a very small sample size, so it may not mean much of anything, but the lack of walks and relatively high strikeout total certainly aren't positive signs. He'll move up to full-season ball this year and has the potential to go through the system quickly if he hits.

24. Aaron Slegers | Starter | DOB: 9/92 | Throws: Right | Draft: 2013-5

YEAR     LV      G     GS      ERA        IP       H     HR      SO     BB
2013     RK+     9      0     0.47      19.0      16      0      18      2

Because of injuries Aaron Slegers barely pitched as a high school senior in 2010 or for Indiana University in 2011 and 2012, but the 6-foot-10 right-hander got healthy last season and started a team-high 18 games for a dominant Hoosiers squad. He was fantastic, going 9-2 with a 2.04 ERA, but still fell to the Twins in the fifth round of the draft and signed for a relatively modest $380,000 bonus as a draft-eligible sophomore.

In addition to his draft stock being lessened by a wide variety of injuries related to both his size and his arm, Slegers also missed surprisingly few bats in college. Despite being able to reach as high as the mid-90s with his fastball and posting a pretty ERA he managed just 59 strikeouts in 106 innings for Indiana and allowed opponents to hit .260. Baseball America's pre-draft scouting report suggested that he got tired as the season wore on and struggled to maintain peak velocity.

However, he had no trouble beating up on rookie-ball hitters in his pro debut, throwing 19 innings with a 0.47 ERA and 18/2 K/BB ratio for Elizabethton. Between college and rookie-ball Slegers served up just one homer in 128 innings and he issued a total of 19 walks, showing excellent control for a pitcher with his size and lack of experience. There's a lot to like here if Slegers can stay healthy and start generating a decent number of strikeouts.

23. Kennys Vargas | First Base | DOB: 8/90 | Bats: Switch | Sign: Puerto Rico

YEAR     LV      PA      AVG      OBP      SLG     HR    XBH     BB     SO
2011     RK+    191     .322     .377     .489      6     17     15     50
2012     A-     186     .318     .419     .610     11     22     28     41
2013     A+     520     .267     .344     .468     19     53     50    105

Kennys Vargas predictably wasn't able to duplicate the huge numbers he posted at low Single-A in 2012, but his move up to high Single-A last season was actually encouraging. For one thing he played 125 games and logged 520 plate appearances after totaling 159 games and 667 plate appearances through his first four seasons. Beyond that he continued to show very good power with 19 homers and 53 extra-base hits, and Vargas cut down on his strikeout rate too.

Vargas is 6-foot-5 and huge, so like with most defensively challenged, low-minors sluggers the questions are whether he'll make consistent enough contact versus more advanced pitching to cancel out a total lack of fielding value. Vargas seems destined to wind up as a designated hitter or a poor defensive first baseman, and in order to be an impact player under those circumstances his bat would have to truly be special.

His power potential certainly has a chance to fall into that category, but it's difficult to gauge that with any sort of accuracy until he moves up another rung or two on the minor-league ladder and the rest of Vargas' offensive game is somewhat lacking for his player type. Still, a hulking switch-hitter with 30 homers and 43 doubles in 166 combined Single-A games through age 22 is certainly not someone to write off.

22. Felix Jorge | Starter | DOB: 1/94 | Throws: Right | Sign: Dominican

YEAR     LV      G     GS      ERA        IP       H     HR      SO     BB
2012     RK-    12      7     2.34      34.2      30      0      37     12
2013     RK+    12     12     2.95      61.0      56      2      72     18

Felix Jorge signed with the Twins out of the Dominican Republic for $250,000 in 2011, made his American debut in 2012, and established himself as someone to watch at rookie-level Elizabethton last season. Pitching the entire season at age 19, he started 12 games with a 2.95 ERA and 72/18 K/BB ratio in 61 innings, posting the second-best strikeout rate in the Appalachian League among all pitchers to start at least 10 games.

Jorge already reaches 92-94 miles per hour with his fastball despite being very skinny and there's plenty of room for projection in his 6-foot-3 frame. In ranking Jorge as one of the Appalachian League's best pitching prospects last season Baseball America noted that his "breaking ball can flash plus with slurvy action and his changeup is developing." If the off-speed stuff doesn't improve he could always wind up in the bullpen, but that's far into the future either way.

I tend to be extremely conservative ranking rookie-ball standouts and particularly rookie-ball pitchers, in part because they're so far away from potentially reaching the majors and in part because so many of them ultimately flame out after posting great numbers as teenagers, but Jorge certainly is very intriguing. He'll make the jump to full-season competition in 2014, which should tell us a lot.

21. Zack Jones | Reliever | DOB: 12/90 | Throws: Right | Draft: 2012-4

YEAR     LV      G     GS      ERA        IP       H     HR      SO     BB
2012     RK+     6      0     0.00       6.0       2      0       9      4
         A-     12      0     3.21      14.0       9      1      25      7
2013     A+     39      0     1.85      48.2      28      2      70     28

Believing that his mid-90s fastball was more telling than his mostly mediocre results in three years at San Jose State the Twins used their 2012 fourth-round pick on Zack Jones. And boy have they been right so far. Jones shifted to the bullpen full time as a pro, added a few miles per hour to his already overpowering heat, and has been almost unhittable with a 1.97 ERA and .165 opponents' batting average, striking out 104 batters in 69 innings.

His control has been terrible with 39 walks and seven wild pitches in 69 frames and despite his overall dominance the Twins had Jones spend all of last season at high Single-A as a 22-year-old, so he hasn't been placed on the fast track to the majors yet. Still, when a young pitcher reaches triple-digits with his fastball and whiffs 38 percent of the batters he's faced through two seasons as a pro that's someone to keep a very close eye on.

The development of his slider figures to be key long term, but Jones and fellow prospect Michael Tonkin give the Twins a pair of high-upside right-handers to potentially fill late-inning setup roles in front of left-hander Glen Perkins. Unfortunately he missed the end of the Arizona Fall League after experiencing numbness in his fingers and then underwent surgery last week for an aneurysm in his upper arm, putting his status for this season in question.
