Top 40 Twins Prospects of 2015: 35, 34, 33, 32, 31

Also in this series: 6-10, 11-15, 16-20, 21-25, 26-30, 36-40.

35. J.R. Graham | Starter | DOB: 1/90 | Throws: Right | Rule 5: Braves

YEAR     LV      G     GS      ERA        IP       H     HR      SO     BB
2012     A+     17     17     2.63     102.2      88      6      68     17
         AA      9      9     3.18      45.1      35      2      42     17
2013     AA      8      8     4.04      35.2      39      0      28     10
2014     AA     27     19     5.55      71.1      79      2      50     26

Selected by the Twins in the Rule 5 draft, J.R. Graham is a one-time top prospect whose career has been derailed by shoulder problems. Graham was the Braves' fourth-round draft pick in 2011 out of Santa Clara and moved quickly through their system, advancing to Double-A in his second pro season. He fared well there at age 22 and that offseason Baseball America ranked Graham as a top-100 prospect, praising his mid-90s fastball and ability to generate ground balls.

However, the diminutive right-hander broke down in 2013, making just eight starts, and last year Graham posted a 5.55 ERA while being limited to 71 innings back at Double-A due to more arm issues. Once on the fast track, Graham is now 25 years old and has yet to advance past Double-A, spending three years there with increasingly poor results. His fastball has dipped into the low-90s and the Braves thought so little of Graham's upside that they left him off the 40-man roster.

Rule 5 picks must remain in the majors for the entire season or be offered back to their original team. Graham has been a starter throughout his career, but shifted to the bullpen last year and could be stashed by the Twins in a middle relief role pretty easily. They did that with Rule 5 pick Ryan Pressly in 2013, giving him 49 low-leverage appearances, and shifting to the bullpen full time could help Graham stay healthy too.

34. 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
2014     A-     26     25     5.14     133.0     147     11      98     50

Ryan Eades was the Twins' second-round draft pick in 2013, selected 43rd overall, and the right-hander from LSU signed for $1.3 million. Yet from the moment he was drafted no one seemed to think much of Eades as a prospect. Quotes about him from team employees were tepid, Baseball America didn't include him in their annual top-10 Twins prospects list which often includes top-50 picks from the previous year, and in general he seemed like an afterthought.

It was odd, because Eades was widely viewed as a top-50 talent within the 2013 draft class and while second-round picks are far from guaranteed to succeed teams don't generally throw them away on players they view as marginal prospects. But sure enough he struggled last year in his full-season pro debut, posting a 5.14 ERA in 133 innings as a 22-year-old at low Single-A facing younger, less experienced competition.

Eades struck out just 6.6 batters per nine innings with poor control and allowed opponents to hit .285 with an .800 OPS against him in a pitcher-friendly league where the average OPS was below .700. Less than two years ago Baseball America wrote that Eades "looked the part of a front-line starter" and the cost for the Twins to acquire him was a top-50 draft pick and $1.3 million, but 150 innings later he looks in danger of being a completely wasted selection.

33. Tanner English | Center Field | DOB: 3/93 | Bats: Right | Draft: 2014-11

YEAR     LV      PA      AVG      OBP      SLG     HR    XBH     BB     SO
2014     RK+    141     .316     .439     .474      3     10     18     27

Tanner English didn't hit much in college, batting .289 with two homers in three years at South Carolina, but the Twins liked his defense, speed, and athleticism enough to draft him in the 11th round. And then he batted .316/.439/.474 in his pro debut at rookie-level Elizabethton, surpassing his 185-game college total with three homers in 32 games and also showing more plate discipline than he displayed against SEC pitching.

College players thriving in rookie-ball isn't really noteworthy, but in this case it stands out a little more than usual because English is good enough defensively in center field that he could make it to the big leagues without hitting much. In their pre-draft scouting report Baseball America called English "one of the better athletes in the college game" and noted that "some evaluators think he could handle center field in the big leagues right now."

English has elite center field range with a very strong arm, and between college and rookie-ball he stole 26 bases in 94 games while being caught just four times last season. If he hits even a little bit English will be a major leaguer, so rookie-ball or not his early showing was worth getting excited about. We should have a much better idea of his overall prospect status after he faces full-season competition for the first time at Single-A this year.

32. Sam Clay | Reliever | DOB: 7/93 | Throws: Left | Draft: 2014-4

YEAR     LV      G     GS      ERA        IP       H     HR      SO     BB
2014     RK+    19      0     5.59      29.0      35      0      44     17

As has become their custom of late the Twins went heavy on college relievers in last year's draft, including Georgia Tech sophomore Sam Clay in the fourth round. Clay had a sparkling 1.26 ERA with 67 strikeouts in 57 innings as a college closer, but the lefty walked 4.6 per nine innings after being a mess as a freshman. He averaged nearly two innings per relief appearance and Baseball America's pre-draft scouting report noted that he "could move into the rotation as a pro."

Clay stayed in the bullpen after signing with the Twins for $400,000 and was awful early on for rookie-level Elizabethton, but finished his pro debut with 16 straight scoreless innings. Even that great stretch lowered his overall ERA to a still-ugly 5.59 and Clay walked 17 batters and uncorked 10 wild pitches in 29 innings while allowing opponents to hit .285. College closers aren't supposed to pitch like that against rookie-ball hitters.

On the other hand, the 16-inning scoreless streak suggests the coaching staff got Clay to address some mechanical issues and within the overall problems he whiffed 44 of the 144 batters he faced for an average of 13.7 strikeouts per nine innings. Clay also allowed zero home runs, so he was hardly being knocked around. He works in the low-90s with his fastball and his curveball gets the most positive reviews. If they can get him to throw strikes the Twins might have something here.

31. Tyler Duffey | Starter | DOB: 12/90 | Throws: Right | Draft: 2012-5

YEAR     LV      G     GS      ERA        IP       H     HR      SO     BB
2012     RK+    12      0     1.42      19.0      10      1      27      2
2013     A-      9      9     2.78      58.1      49      5      47      6
         A+     15      9     4.45      62.2      67      3      44     17
2014     A+      4      4     2.82      22.1      22      0      13      5
         AA     18     18     3.80     111.1     104     14      84     19
         AAA     3      3     3.94      16.0      16      3      16      6

Rice University had co-closers in 2012 and the Twins drafted both of them, taking J.T. Chargois in the second round and Tyler Duffey in the fifth round. Chargois stayed in the bullpen and is currently making his way back from Tommy John elbow surgery, whereas Duffey shifted to the rotation and reached Triple-A last season at age 23. He pitched for Fort Myers, New Britain, and Rochester last year, making 25 total starts with a 13-3 record and 3.68 ERA.

Duffey has shown excellent control as a pro, walking just 1.7 batters per nine innings, but he's struggled to generate strikeouts. In fact, he barely has more strikeouts (196) in 259 innings as a pro starter than he had (189) in 153 innings as a college reliever. Duffey shut down right-handed hitters last season, but allowed an OPS that was 200 points higher versus lefties, suggesting that his off-speed stuff needs some work.

Duffey's low-90s fastball also limits his upside, but the Twins certainly value starters who pound the strike zone with mediocre raw stuff and occasionally those guys have decent runs of success. Going heavy on college relievers in the 2012 draft with plans to turn them into pro starters has been a bust for the Twins thanks to injuries and ineffectiveness, but Duffey has stayed healthy and shown the potential to contribute in the back of a rotation.

Top 40 Twins Prospects of 2015: 40, 39, 38, 37, 36

Also in this series: 6-10, 11-15, 16-20, 21-25, 26-30, 31-35.

40. A.J. Achter | Reliever | DOB: 8/88 | Throws: Right | Draft: 2010-46

YEAR     LV      G     GS      ERA        IP       H     HR      SO     BB
2012     A-     18      1     2.48      40.0      33      5      49     12
         A+     19      0     0.79      34.1      21      0      37      3
2013     AA     25      0     2.21      36.2      28      3      36     19
         AAA    16      0     3.04      23.2      17      4      20     14
2014     AAA    40      0     2.38      72.0      44      4      69     24

A.J. Achter was a 46th-round draft pick out of Michigan State in 2010 and posted a 4.52 ERA in 2011 as a starter at low Single-A, but he shifted to the bullpen in 2012 and has a combined 2.10 ERA in 213 innings as a reliever since then. That includes a 2.17 ERA and 80/25 K/BB ratio in 79 innings last season, mostly at Triple-A, which was enough to get him added to the 40-man roster as a September call-up.

However, his shiny ERAs come with good but not exceptional strikeout rates and Achter's control is mediocre. He's done an amazing job limiting hits, including a .173 opponents' batting average last season, but that was driven by an unsustainably great .228 batting average on balls in play. Toss in underwhelming velocity and his odds of sticking in the big leagues don't seem particularly good, but at age 26 he warrants a "why not?" look.

Achter got into seven games for the Twins as a reliever and posted another nice-looking 3.27 ERA, but he managed just five strikeouts in 11 innings, opponents hit .304/.347/.522 off him, and his average fastball clocked in at 90.2 miles per hour. Middle relief is Achter's upside and the Twins' bullpen depth chart is pretty crowded, but the fact that they kept him on the 40-man roster all offseason suggests they're interested in giving him another shot at some point.

39. Logan Darnell | Starter | DOB: 2/89 | Throws: Left | Draft: 2010-6

YEAR     LV      G     GS      ERA        IP       H     HR      SO     BB
2012     AA     28     28     5.08     156.0     193     22      98     47
2013     AA     15     15     2.61      96.2      96      4      77     23
        AAA     12     11     4.26      57.0      63      5      43     22
2014    AAA     23     19     3.60     115.0     108     16      90     49
        MLB      7      4     7.13      24.0      31      5      22      8

A solid 2013 season between Double-A and Triple-A got Logan Darnell added to the 40-man roster, but the 2010 sixth-round pick spent most of last year back at Triple-A and managed just 90 strikeouts in 115 innings while walking 3.8 batters per nine frames. That poor strikeout rate matches his high-80s fastball velocity and Darnell has an underwhelming 3.81 ERA and 133/71 K/BB ratio in 172 career innings at Triple-A.

He also got knocked around in his first taste of the majors, allowing 20 runs in 24 innings for the Twins at age 25. Given his sub par velocity, mediocre control, and inability to hold right-handed hitters in check it's hard to imagine Darnell having sustained success as a starter in the majors, but the left-hander could find a home in the bullpen as a southpaw specialist. Of course, that role is such that the same can be said for nearly every decent lefty in the minors.

In the minors during the past two seasons Darnell held lefties to a combined .228 batting average and 74/18 K/BB ratio, whereas righties batted .285 off him over that same span. Regardless of the role Darnell is behind a lot of names on the Twins' pitching depth chart heading into 2015 and seems like a candidate to be removed from the 40-man roster if space is needed early, but if given a chance he could carve out a useful niche in middle relief.

38. Levi Michael | Second Base | DOB: 2/91 | Bats: Switch | Draft: 2011-1

YEAR     LV      PA      AVG      OBP      SLG     HR    XBH     BB     SO
2012     A+     512     .246     .339     .311      2     20     56     82
2013     A+     375     .229     .331     .340      4     23     49     67
2014     A+     201     .305     .375     .395      1     12     19     25
         AA      63     .340     .444     .358      0      1      7     11

Levi Michael was billed as being close to MLB-ready when the Twins drafted the North Carolina shortstop in the first round in 2011 and the pick made sense for a team that had long struggled to develop capable middle infielders. They showed their faith in his readiness by sending him directly to high Single-A, but three years later Michael was still stuck there. Nagging injuries repeatedly derailed Michael's development and the solid power he showed in college disappeared.

Last season, in his third go-around at Fort Myers, he finally showed some promise by hitting .305 in 45 games to earn a promotion to Double-A, where he hit .340 in 15 games. Those lofty batting averages are misleading because he managed just one home run, but Michael controlled the strike zone well. Even within the overall struggles Michael always made plenty of contact and drew some walks, suggesting the switch-hitter could have value even if the power is gone for good.

Unfortunately he's no longer a shortstop. Dating back to college there were questions about his ability to stick at shortstop long term and last season Michael played almost exclusively second base at both levels. Not only does that raise the bar for his offensive production, it makes it much harder for Michael to potentially stick in the majors as a utility infielder. At age 24 and with just 15 career games above Single-A it's time for Michael to sink or swim.

37. Stephen Pryor | Reliever | DOB: 7/89 | Throws: Right | Trade: Mariners

YEAR     LV      G     GS      ERA        IP       H     HR      SO     BB
2012     AA     11      0     1.12      16.0       7      0      24      5
         AAA    16      0     0.00      20.0      11      0      20     11
         MLB    26      0     3.91      23.0      22      5      27     13
2013
2014     AAA    38      0     3.16      51.1      32      6      49     34

Acquired from the Mariners on July 24 as the Twins' return in the Kendrys Morales salary dump, Stephen Pryor was one of the few players on the 40-man roster not to get a September call-up to Minnesota. However, he remained on the 40-man roster all offseason and presumably the front office has enough patience in the 25-year-old right-hander to see if he can get healthy and regain his old velocity after missing most of 2013 and part of 2014 following shoulder surgery.

Before the injury Pryor looked destined for a late-inning bullpen role in Seattle. As a 22-year-old in 2012 he blitzed through the minors, going from Single-A to Double-A to Triple-A before debuting with the Mariners in June. Overall that season Pryor posted a 0.93 ERA and 47 strikeouts in 39 innings as a minor leaguer and then racked up 27 strikeouts in 23 innings for the Mariners while averaging 96.3 miles per hour with his fastball.

His arm gave out in 2013 and while Pryor returned last season to log 55 innings in the minors and make two appearances for the Mariners he was a shell of his former self, throwing in the low-90s with less than one strikeout per inning. Pryor has always struggled to consistently throw strikes and control problems that can be overlooked when attached to a high-90s fastball may be tough to overcome if that velocity is gone for good.

36. Lester Oliveros | Reliever | DOB: 5/88 | Throws: Right | Trade: Tigers

YEAR     LV      G     GS      ERA        IP       H     HR      SO     BB
2012     AA     13      0     1.42      19.0      10      0      16      7
         AAA    19      0     3.07      29.1      24      2      35      8
2013
2014     AA     26      0     0.89      30.1      17      0      36     14
         AAA    24      0     2.29      35.1      27      0      52     13

Lester Oliveros was acquired from the Tigers in the 2011 trade for Delmon Young and missed most of 2013 recovering from Tommy John elbow surgery. He returned last year and was better than ever between Double-A and Triple-A with a 1.64 ERA and 88 strikeouts in 66 innings while holding opponents to a .187 opponents' batting average with zero home runs. And then naturally Oliveros served up a homer to the first batter he faced as a September call-up.

Oliveras has always had a big fastball, averaging 94 miles per hour as a big leaguer before and after elbow surgery. He's also always had iffy control, with nearly four walks per nine innings in the minors. He made some minor strides with his control last season when a lot of pitchers see their walk rate rise after surgery, but there's still plenty of work to be done in terms of harnessing his raw stuff.

As a 27-year-old reliever Oliveros is stretching the definition of "prospect" and expectations should certainly be modest, but when someone with a mid-90s fastball averages more than 11 strikeouts per nine innings at Double-A and Triple-A he's generally worth an extended look. Unfortunately for Oliveros, because the Twins decided against overhauling their bullpen this offseason he faces an uphill battle for an Opening Day roster spot.

Top 40 Twins Prospects of 2014: 5, 4, 3, 2, 1

Also in this series: 6-10, 11-15, 16-20, 21-25, 26-30, 31-35, 36-40.

5. Jose Berrios | Starter | DOB: 5/94 | Throws: Right | Draft: 2012-1

YEAR     LV      G     GS      ERA        IP       H     HR      SO     BB
2012     RK-     8      1     1.08      16.2       7      0      27      3

2013     A-     19     19     3.99     103.2     105      6     100     40

Selected out of a Puerto Rico high school 30 picks after Byron Buxton in the 2012 draft, Jose Berrios had a great rookie-ball debut and then made the jump to full-season competition last year at low Single-A. While his 3.99 ERA and .265 opponents' batting average were unimpressive, Berrios struck out 100 batters in 104 innings and allowed just six homers while being one of only eight teenagers in the Midwest League to log at least 100 innings.

Obviously it would be ideal to see Berrios overpowering hitters in the low minors, but missing plenty of bats and holding his own overall as a teenager is a very good sign. Berrios throws hard and receives praise for his off-speed stuff, but like most 19-year-olds his control needs work and one potential red flag is that he's been a fly-ball pitcher. That tendency usually gets more extreme further up the organizational ladder, so it'll be something to keep an eye on.

Berrios is a slight 6-foot-1 and so far the Twins have been cautious with his workload by limiting his starts in-season and convincing him to skip winter ball, but he'll likely be given a longer leash this year at high Single-A. He tends to get lost in the shuffle of what has become a stacked deck of Twins prospects, but in some recent years Berrios would have been the team's top pitching prospect and his long-term upside is substantial.

4. Kohl Stewart | Starter | DOB: 10/94 | Throws: Right | Draft: 2013-1

From 2005-2012 the Twins used a top-50 draft pick on seven college pitchers compared to just one high school pitcher, but they bucked that trend in a big way last year by picking 18-year-old Texas right-hander Kohl Stewart fourth overall. Considered the top high school talent in the draft class that saw college stars go 1-2-3, Stewart dominated rookie-ball hitters in his pro debut with a 1.35 ERA and 24/4 K/BB ratio in 20 innings.

Not only did Stewart have video game-like numbers as a senior with a 0.18 ERA in eight starts, he was a two-sport star and ESPN ranked him as the sixth-best prep quarterback in the country. He committed to play football at Texas A&M, but Stewart signed for $4.5 million instead of trying to replace Heisman Trophy winner Johnny Manziel. He throws a mid-90s fastball, but both ESPN and Baseball America peg Stewart's slider as his best pitch.

Across baseball during the past decade using top-five picks on high school pitchers has proven to be a terrible investment, but the Twins taking such an uncharacteristic gamble suggests they truly believe Stewart is a special prospect. On draft day scouting director Deron Johnson described Stewart's ceiling as "unlimited" and given their recent inability to develop front-line starters the high-risk, high-reward approach makes sense.

3. Alex Meyer | Starter | DOB: 1/90 | Throws: Right | Trade: Nationals

YEAR     LV      G     GS      ERA        IP       H     HR      SO     BB

Despite being 23 years old Alex Meyer had yet to pitch above Single-A when the Twins acquired him from the Nationals for Denard Span last offseason, but he made the jump to Double-A last season and posted a 3.21 ERA with 10.8 strikeouts per nine innings and a .227 opponents' batting average. Unfortunately a shoulder injury limited Meyer to 13 starts and 70 innings, but he was healthy enough to pitch in the Arizona Fall League and threw 28 strong innings.

Meyer was the 23rd overall pick in the 2011 draft out of the University of Kentucky and the right-hander has the raw stuff to match his 6-foot-9 frame, throwing in the mid-90s with his fastball and complementing it with a hard curveball and useful changeup. Last season among all Eastern League pitchers with at least a dozen starts Meyer ranked second in strikeout rate and sixth in ERA while actually faring better versus lefties than righties.

He induces a ton of ground balls and has allowed a grand total of just nine homers in 207 innings, but not surprisingly for a huge pitcher who throws extremely hard Meyer's control is pretty shaky. If things go well for Meyer this season he could be in Minnesota by the All-Star break and he has the potential to be the first top-of-the-rotation starter the Twins have had since Johan Santana, but first he'll need to stay healthy and shut down Triple-A hitters.

2. Miguel Sano | Third Base | DOB: 5/93 | Bats: Right | Sign: Dominican

Miguel Sano crushed high Single-A pitching to begin last season, hitting .330/.424/.655 with 16 homers in 56 games to earn a promotion to Double-A, where he continued to show huge power with 19 homers in 67 games but saw his batting average drop nearly 100 points. And yet even while hitting just .236 there only seven Eastern League hitters had a higher OPS than Sano and he was one of only four 20-and-under position players in the entire league.

Overall he hit .280/.382/.610 with 35 homers, 70 total extra-base hits, and 65 walks. He even swiped 11 bases to show that he's got some wheels at 6-foot-5 and 250 pounds. And then just as Sano was on the verge of the majors, perhaps even having a slight chance to win an Opening Day job, he had elbow problems while playing winter ball. Rest and rehab worked, but only briefly, and after a setback early in spring training he underwent Tommy John elbow surgery.

Even before the elbow injury Sano was questionable to stick at third base long term, but the vast majority of his value will come from his bat no matter where he is defensively. Missing a year of development at age 21 is unfortunate, especially since Sano's high strikeout rate is an area that could use improvement, but he may get some late-season at-bats as a designated hitter. His timetable has been delayed and his picture is a little blurrier, but Sano remains a stud.

1. Byron Buxton | Center Field | DOB: 12/93 | Bats: Right | Draft: 2012-1

Considered the highest-upside prospect in the 2012 draft class, Byron Buxton fell to the Twins with the No. 2 pick when the Astros chose high school shortstop Carlos Correa instead. At the time there were questions about whether Buxton was ready to thrive as a pro after facing sub par competition as a Georgia high schooler, but he made those disappear almost immediately and two years later he's the consensus No. 1 prospect in all of baseball.

Buxton hit .341 in 68 games at low Single-A and batted .326 in 57 games following a promotion to high Single-A, where he was the only teenage hitter in the entire Florida State League. Overall as a 19-year-old in his first full season he batted .334/.424/.520 with 49 extra-base hits, 55 steals, and 76 walks in 125 games, which would be incredible for, say, a plodding first baseman. Buxton is a potential Gold Glove-caliber center fielder with truly elite speed and athleticism. He's a freak.

His high walk rate and reasonable strikeout rate were particularly encouraging to see, because it's tough to predict how well raw high school hitters will control the strike zone. Single-A is still just Single-A and he needs to prove himself against advanced competition, but Buxton's combination of age, tools, skill set, and production is nearly flawless to this point. As long as a spring training wrist injury proves relatively minor he has a shot to debut for the Twins before his 21st birthday.

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

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

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

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

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

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.

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

2012     A+     547     .286     .329     .410      8     38     29     77

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

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.

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.
