15. Max Kepler | Center Field | DOB: 2/93 | Bats: Left | Sign: Germany YEAR LV PA AVG OBP SLG HR XBH BB SO 2012 RK+ 269 .297 .387 .539 10 31 27 33 2013 A- 263 .237 .312 .424 9 23 24 43 2014 A+ 407 .264 .333 .393 5 31 34 62
As a 16-year-old Max Kepler was big and fast with lots of tools and a unique background that included his parents meeting as performers in the German ballet, so when the Twins signed him out of Germany for $800,000 he was viewed as an intriguing, high-upside prospect. Five seasons later some of that intrigue and upside have vanished, in part because Kepler has struggled to stay healthy and in part because his performance beyond rookie-ball has underwhelmed.
Kepler played 163 games at Single-A during the past two seasons, hitting .253/.325/.405 with 14 homers. He also seems less and less likely to stick in center field, playing quite a bit of right field and first base. On the other hand Kepler was one of the Florida State League's youngest regulars last season at age 21, so even holding his own there is a positive sign. And after a bad first three months Kepler finished the year on a high note by hitting .303/.359/.442 in July and August.
Kepler is no longer incredibly young and no longer oozes upside, so now he simply needs to start hitting and in particular turn his 6-foot-4 frame and power potential into actual homers. Despite not playing above Single-A he was added to the 40-man roster, which means the clock is ticking on Kepler showing he belongs in the majors and the door is open for him to reach Minnesota at some point this season if he plays well.
14. Michael Cederoth | Starter | DOB: 11/92 | Throws: Right | Draft: 2014-3 YEAR LV G GS ERA IP H HR SO BB 2014 RK+ 11 10 3.55 45.2 41 1 42 18
In their ongoing effort to add more high-end velocity to the organization the Twins picked San Diego State right-hander Michael Cederoth in the third round last year. Cederoth was a starter in 2012 and 2013, but shifted to the bullpen in 2014 and topped out at 100 miles per hour while racking up 20 saves with a 2.28 ERA and 55 strikeouts in 52 innings. Despite that relief success Cederoth made his pro debut as a starter and fared pretty well for rookie-level Elizabethton.
Making the abbreviated outings that are common for rookie-ball starters, he posted a 3.55 ERA with just one homer allowed and a 42/18 K/BB ratio in 46 innings. His fastball predictably wasn't able to reach triple-digits as a starter, but Cederoth worked in the mid-90s and his control was encouraging. He walked 3.5 per nine innings, which is a lot, but in college Cederoth walked 5.2 per nine innings.
Converting hard-throwing college relievers into pro starters has repeatedly gone poorly for the Twins in recent years and Cederoth's mediocre results as a college starter leave even less room for optimism, but he's 6-foot-6 with an equally big fastball and there's always a role in the majors for that profile even if it's yet to be determined. This year he'll make the jump up to full-season competition at Single-A and try to develop his secondary pitches.
13. Amaurys Minier | Left Field | DOB: 1/96 | Bats: Switch | Sign: Dominican YEAR LV PA AVG OBP SLG HR XBH BB SO 2013 RK- 119 .214 .252 .455 6 13 6 29 2014 RK- 205 .292 .405 .520 8 21 29 52
When the Twins signed Amaurys Minier for $1.4 million as a 16-year-old out of the Dominican Republic there were immediate comparisons to Miguel Sano, but those quieted down when he hit .214 at rookie-ball in his pro debut. However, within the ugly batting average Minier showed a ton of power and last season he made it clear why the Twins were so high on him by crushing the Gulf Coast League in his second go-around.
Minier hit .292/.405/.520 with eight homers, 21 total extra-base hits, and 29 walks in 53 games, leading the GCL in homers and ranking third in both slugging percentage and OPS. And he did so while playing the entire season at age 18. He was signed as a shortstop, debuted at third base, and played left field and first base last season, but his eventual defensive home is secondary to Minier's offensive upside as a switch-hitting slugger.
Rookie-ball numbers should be viewed skeptically because the level of competition is inconsistent and the sample size is small, but Minier's production was special. He posted a .925 OPS, which is the highest by any Twins prospect in the Gulf Coast League during the past decade. And the only Twins prospects in the Gulf Coast League within 30 points of his OPS from 2005-2014 were Chris Parmelee (.901 in 2006), Aaron Hicks (.900 in 2008), and Kennys Vargas (.895 in 2010).
12. 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 2014 RK+ 6 6 2.79 29.0 23 1 26 10 A- 8 8 3.19 36.2 31 1 44 11
Stephen Gonsalves was viewed as a first-round talent in 2013, but fell to the Twins in the fourth round following a suspension during his senior year of high school in California and then signed for second-round money at $700,000. His pro debut was impressive, as the 6-foot-5 lefty logged 28 rookie-ball innings with a 0.95 ERA and 39/11 K/BB ratio without allowing a homer. He stayed in rookie-ball to begin last season and then moved up to low Single-A, where he thrived at age 19.
Despite being younger than around 90 percent of the pitchers in the Midwest League he started eight games for Cedar Rapids with a 3.19 ERA and 44/11 K/BB ratio in 37 innings, striking out 30 percent of the batters he faced while opponents hit .228 with one homer. Toss in his rookie-ball numbers and through two pro seasons Gonsalves has a combined 2.39 ERA with 109 strikeouts and two homers allowed in 94 innings.
His control still needs work and Gonsalves' off-speed pitches generally receive mediocre reviews, both of which may need to change for his success to continue against tougher competition if his fastball stays in the low-90s. He also needs to handle a full-season workload for the first time at age 20, so expectations should be held in check, but Gonsalves looks like a potential mid-rotation starter down the road if things go well.
11. 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 2014 AAA 18 18 2.84 98.1 75 4 94 39 MLB 10 9 7.88 45.2 59 7 44 22
When the Twins acquired Trevor May from the Phillies along with Vance Worley in exchange for Ben Revere he was coming off an underwhelming 2012 season at Double-A. They had him repeat the level in 2013 with similarly mediocre results, but May moved up to Triple-A last year and took a big step forward. He posted a 2.84 ERA with 94 strikeouts in 98 innings, cut his walk rate by 15 percent, and allowed just four homers after previously struggling to limit long balls.
That earned May an August call-up to the majors, where everything unraveled. His debut was a mess, as he issued seven walks in two innings and 10 of 15 batters reached base. He continued to struggle for the next few starts and finished with a hideous 7.88 ERA, but May actually showed signs of progress down the stretch. He posted a strong 41/9 K/BB ratio in his final 37 innings, averaged 92 miles per hour with his fastball, and generated a solid number of swinging strikes.
There's no doubt that it was a sour first taste of the majors, but May at least showed glimpses of his potential to match the 18 good starts at Triple-A. He'll likely be a part of the Twins' rotation at some point in 2015 and if May can throw strikes he's capable of being a mid-rotation starter. At age 25 and with 400 innings between Double-A and Triple-A his leash may not be particularly long considering the Twins were so hesitant to promote him in the first place.
