20. Tom Stuifbergen | Starter | DOB: 9/88 | Throws: Right | Sign: Netherlands YEAR LV G GS ERA IP H HR SO BB 2009 RK+ 13 13 3.28 79.2 79 4 69 6 2010 A- 19 17 2.98 93.2 99 5 88 23
Tom Stuifbergen signed with the Twins out of the Netherlands as an 18-year-old in 2006 and missed all of 2008 following shoulder surgery, but bounced back to be a member of the Dutch pitching staff coached by Bert Blyleven in the 2009 World Baseball Classic. At the time he had never thrown a pitch above rookie-ball, yet Stuifbergen matched up with Ubaldo Jimenez and tossed four shutout innings versus the Dominican Republic in the tournament's biggest upset.
After playing in the WBC he spent 2009 at rookie-level Elizabethton, posting a brilliant 69-to-6 strikeout-to-walk ratio in 80 innings while inducing 64 percent ground balls, but Stuifbergen also missed some time with elbow problems. Last season was a similar story, as the 6-foot-4 right-hander fared very well at low Single-A with a 2.98 ERA and 88/23 K/BB ratio in 94 innings, but missed a chunk of the season with more elbow issues.
Clearly staying healthy is key for Stuifbergen, who's appeared in just 40 pro games, but even in limited action a 169/33 K/BB ratio in 188 innings is impressive and he's still just 22 years old. His raw stuff isn't overpowering, but Stuifbergen throws strikes, misses a fair number of bats, and induces grounders in bunches. Right now Nick Blackburn seems like a decent comparison, but if he can stay healthy for a while and add some velocity he could have mid-rotation upside.
19. Chris Parmelee | First Base | DOB: 2/88 | Bats: Left | Draft: 2006-1 YEAR LV PA AVG OBP SLG HR XBH BB SO 2008 A- 289 .239 .385 .496 14 27 52 83 2009 A+ 501 .258 .359 .441 16 44 65 109 2010 A+ 93 .338 .430 .463 2 5 13 11 AA 463 .275 .341 .389 6 33 43 70
Through his first four pro seasons Chris Parmelee stood out in a system full of toolsy, athletic hitting prospects because his game was about power and patience, but last year at the Twins' urging the 20th overall pick in the 2006 draft totally overhauled his approach. It accomplished what the Twins had in mind, as he hit .285 between high Single-A and Double-A after coming into the season as a .250 hitter and also struck out 43 percent less often than his career rate.
Unfortunately, as his contact and average increased Parmelee's power vanished. He homered just eight times in 133 games and his Isolated Power was 42 percent below his career mark. His walk rate also fell by 22 percent. Add it all up and despite a 35-point uptick in average and 43 percent fewer whiffs his on-base percentage, slugging percentage, and OPS were all lower than each of the previous two years. In other words, the change in approach made him worse.
Or at least it did in 2010. Clearly the Twins felt that, despite solid overall production in the low minors, Parmelee's original approach made him unlikely to succeed in the majors. And they're probably right, as most of the majors' best low-average, high-power hitters actually hit above .280 in the minors. On other hand, regardless of the approach being used if Parmelee can't rediscover his power everything else will be a moot point. Power is the non-negotiable part.
18. Alex Burnett | Reliever | DOB: 7/87 | Throws: Right | Draft: 2005-12 YEAR LV G GS ERA IP H HR SO BB 2008 A+ 28 25 3.76 143.2 151 12 84 36 2009 A+ 18 0 1.99 22.2 14 0 26 7 AA 40 0 1.79 55.1 36 2 52 19 2010 AAA 14 0 5.49 19.2 26 1 18 8 MLB 41 0 5.29 47.2 52 6 37 23
Alex Burnett thrived while transitioning from starter to reliever at high Single-A and Double-A in 2009 and last April the Twins bypassed several more experienced relief prospects to call him up when they needed immediate bullpen help with injuries to Clay Condrey and Jose Mijares. He found success right away, throwing 31 innings with a 26-to-11 strikeout-to-walk ratio and 2.30 ERA through mid-June, but then fell apart and kept struggling after a demotion to Triple-A.
Burnett allowed 20 runs in his final 16 innings with the Twins and had a 5.49 ERA in 20 innings at Triple-A after posting a 1.85 mark between Single-A and Double-A in 2009. It wasn't pretty, but Burnett's low-90s fastball and mid-80s slider combination showed plenty of potential and it's important to remember that he was a 22-year-old in his second season of relief work. Plus, with a 4.54 xFIP in his 48-inning debut Burnett pitched better than his 5.29 ERA shows.
He'll get another chance to establish himself in the majors this year, perhaps right away, and is capable of becoming a key component of the Twins' bullpen long term. Burnett has thrown a total of 98 innings in the minors since becoming a reliever, posting a 2.57 ERA and 96/34 K/BB ratio while allowing just three homers. He obviously needs to bounce back and iron out some rough spots, but it wouldn't be surprising to see him in a late-inning role down the stretch.
17. Carlos Gutierrez | Reliever | DOB: 9/86 | Throws: Right | Draft: 2008-1 YEAR LV G GS ERA IP H HR SO BB 2008 A+ 16 0 2.10 25.2 23 0 19 7 2009 A+ 11 10 1.32 54.2 37 1 33 22 AA 22 6 6.19 52.1 62 6 32 24 2010 AA 32 16 4.57 122.0 136 7 81 50
Carlos Gutierrez began his college career as a starter, but moved to the bullpen after Tommy John surgery and served as the University of Miami's closer in 2008 before the Twins selected him 27th overall with the compensatory draft pick received for the Angels signing Torii Hunter. In the three seasons since then Gutierrez has moved back and forth between the rotation and bullpen, but his success as a starter has been limited and he projects as a full-time reliever.
Because of the frequent role changes it's difficult to get a handle on Gutierrez's upside by way of his numbers. He's been dominant at times and awful at others, but the overall performance is mediocre with a 3.93 ERA and 171-to-105 strikeout-to-walk ratio in 259 innings. However, as more or less a one-pitch pitcher Gutierrez should fare better when working exclusively as a reliever and that one pitch is a sinker that induced 60 percent ground balls at Double-A.
Once the Twins cease trying him as a starter Gutierrez has a chance to move very quickly and perhaps even join the big-league bullpen this year, but I'd like to see him thrive in a relief role for a few months before assuming he'll make a late-inning impact. Right now Gutierrez's upside is based more on the praise for his "power sinker" than his actual performance, but mid-90s velocity and a 60 percent ground-ball rate are pretty solid building blocks for relief success.
16. Max Kepler | Center Field | DOB: 2/93 | Bats: Left | Sign: Germany YEAR LV PA AVG OBP SLG HR XBH BB SO 2010 RK- 153 .286 .346 .343 0 7 13 27
American-born Kathy Kepler and Polish-born Marek Rozycki met while starring together in the Berlin ballet and their son, Max Kepler, signed with the Twins out of Germany as a 16-year-old in July of 2009, getting an $800,000 bonus that ranks as the largest ever given to a European position player. When he wasn't busy getting his driver's license and going to high school in a foreign country, Kepler held his own while debuting in the rookie-level Gulf Coast League.
He showed limited power, but hit .286 with a decent walk rate and, most importantly for a raw 17-year-old, continued to impress with his physical tools. Asked to assess Kepler's first season Twins vice president of player personnel Mike Radcliff focused primarily on his work ethic and success "navigating the baseball life on and off the field," but also pointed to his "unbelievably athletic body ... pretty swing, terrific bat speed, and strength." In other words, so far so good.
For now at least Kepler projects as a potential center fielder, but that may change quickly once his 6-foot-4 frame fills out and he played all three outfield spots in rookie-ball, where Baseball America named him the ninth-best prospect in the upside-filled GCL. He's likely still a season or two from facing full-season competition, so thinking about how Kepler might look roaming the outfield at Target Field is very premature, but if he gets there the ceiling could be sky high.
