25. 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 2014 A- 20 20 4.53 113.1 118 7 90 20 A+ 3 3 3.32 19.0 14 2 12 4
Aaron Slegers battled multiple injuries in high school and early in his college career at Indiana, but the 6-foot-10 right-hander got healthy in 2013 and was drafted by the Twins in the fifth round after a strong sophomore year. He signed for $380,000 and debuted at rookie-level Elizabethton by allowing just one run in 19 innings with an 18/2 K/BB ratio, looking good following concerns about his tiring down the stretch for the Hoosiers amid a career-high workload.
Slegers moved up to low Single-A last year and posted a poor 4.53 ERA in 20 starts, but his 90/20 K/BB ratio in 113 innings was solid and he allowed just seven homers. He missed very few bats in college, so even a modest strikeout rate of 7.2 per nine innings was a step in the right direction. Slegers then finished the year with a three-start promotion to high Single-A, faring well there at age 21.
Slegers' velocity doesn't match his intimating 6-foot-10 frame, but he throws in the low-90s and induces lots of ground balls. For a pitcher that size avoiding nagging injuries and maintaining consistent mechanics are always question marks, but Slegers seems to have gotten past his previous health issues and his control has been fantastic with just 1.5 walks per nine innings. He's not going to be the next Randy Johnson, but Slegers is an intriguing prospect.
24. Mitch Garver | Catcher | DOB: 1/91 | Bats: Right | Draft: 2013-9 YEAR LV PA AVG OBP SLG HR XBH BB SO 2013 RK+ 225 .243 .313 .366 2 19 19 31 2014 A- 504 .298 .399 .481 16 46 61 65
Mitch Garver put up huge college numbers in a very hitter-friendly environment at New Mexico, batting .383 with 72 extra-base hits in 120 games during his junior and senior years. Considered by many to be a low-upside "senior sign" in the 2013 draft, he fell to the Twins in the ninth round and agreed to a $40,000 signing bonus well below slot value. And then Garver struggled in his pro debut at rookie-ball, hitting just .243/.313/.366 with two homers in 56 games.
Tossed onto the non-prospect pile, Garver bounced back in a big way last season at low Single-A, batting .298/.399/.481 with 16 homers, 46 total extra-base hits, and nearly as many walks (61) as strikeouts (65) in 120 games. Among all Midwest League hitters he ranked fourth in batting average, third in on-base percentage, fourth in slugging percentage, and third in OPS, producing an .880 mark that was 27 percent better than the league average.
Reviews of his defense behind the plate are mixed and Garver saw about half of his 2014 action at designated hitter, but he threw out a respectable 32 percent of steal attempts. At age 23 he was old for the Midwest League, so it's possible Garver was just beating up on inexperienced pitching after playing four seasons of college ball. Either way, when a catcher puts up big numbers in the minors after putting up big numbers in college he's worth keeping an eye on.
23. 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 2014 RK- 6 1 3.38 5.1 3 0 9 4 A+ 5 0 0.00 5.0 3 0 5 2
After middling results as a college starter Zack Jones shifted to the bullpen full time when the Twins took him in the fourth round of the 2012 draft and posted video game-like numbers through two pro seasons with a 1.97 ERA, .165 opponents' batting average, and 13.6 strikeouts per nine innings. And he had the raw stuff to match, consistently working in the mid-90s with his fastball and topping out in the triple digits.
While pitching in the Arizona Fall League he experienced finger numbness and was shut down, eventually undergoing surgery for an aneurysm in his shoulder. Jones missed the entire first half of last season before rehabbing in the rookie-level Gulf Coast League and then rejoined the high Single-A bullpen to make a handful of appearances down the stretch. And to tie a nice bow on his comeback, he returned to the Arizona Fall League and allowed zero runs in 11 games.
Reports on Jones' velocity were more or less in line with his outstanding pre-surgery heat, but including the AFL he walked 18 batters in 21 innings to show that he may not have cleared every hurdle yet. His control has always been a red flag, with more than 5.0 walks per nine innings in each of his three pro campaigns. Before the career-threatening injury Jones was on the fast track and he's capable of reaching the majors in 2015, but he needs to stay healthy and throw strikes.
22. Travis Harrison | Left Field | 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 2014 A+ 537 .269 .361 .365 3 37 64 86
When the Twins made Travis Harrison the 50th overall pick in the 2011 draft out of a California high school he was billed as one of the best power-hitting prospects in the class, but that has not translated to the pros yet. Harrison hit 20 homers in 189 games through his first two seasons and then his power disappeared in 2014, as he went deep just three times in 129 games and slugged .365 at high Single-A.
Three homers in 537 plate appearances is hard to ignore, but it's worth noting the Florida State League is a tough place to hit for power and Harrison was among the youngest regulars at 21. He also ranked second in the league with 33 doubles, suggesting he was making hard contact even if it didn't result in fly balls going over fences, and Harrison cut way down on his strikeouts while maintaining a strong walk rate on the way to a nice 86/64 K/BB ratio.
There's some stuff to like within Harrison's offensive skill set, but the lack of power is troubling and doubly so because he's already shifted from third base to left field defensively. Any further moves down the defensive spectrum would leave Harrison with zero defensive value and at that point he'd need to develop into a slugger to work his way into the Twins' plans. Even getting back to 15 homers while keeping his strikeouts down would make 2015 a success for Harrison.
21. Jake Reed | Reliever | DOB: 9/92 | Throws: Right | Draft: 2014-5 YEAR LV G GS ERA IP H HR SO BB 2014 RK+ 4 0 0.00 6.0 1 0 8 0 A- 16 0 0.36 25.0 10 0 31 3
After two mediocre seasons in Oregon's rotation Jake Reed shifted to the bullpen last year and went 4-1 with 13 saves and a 1.95 ERA in 31 appearances. His secondary numbers weren't as impressive, with 34 strikeouts versus 15 walks in 37 innings, but Reed had no such issues with secondary numbers in his pro debut. Drafted in the fifth round, he signed for $350,000 and made quick work of rookie-ball before a promotion to low Single-A.
Between the two levels Reed allowed one run in 20 appearances, racking up a 39/3 K/BB ratio in 31 innings while limiting opponents to a .105 batting average and zero homers. It'd be tough to dominate any more than that, even accounting for the fact that college pitchers are supposed to dominate low-minors hitters. Twins pitching draftees often beat up on inexperienced competition, but Reed actually has the impressive raw stuff to match his numbers.
He works in the mid-90s with his fastball and his slider also gets positive reviews, leading to ground balls in bunches. Righties hit .085 with 12 strikeouts per walk and lefties hit .130 with 15 strikeouts per walk. Assuming that the Twins don't try to move him back in the rotation Reed has a chance to move quickly through the system and could join fellow hard-throwing 2014 draftee Nick Burdi in the big-league bullpen by 2016.
