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.
