But there are a few more, who might not be the biggest names in the farm system, but are players that could surprise during the coming season. Let's take a look at a few of them:
Danny Santana: He is already on the 40-man roster and he put together a very productive year at Fort Myers last season. As a 22-year old, he should be given a starting middle infield job at AA-New Britain. This would mean that he is getting closer to making his big league debut.
Santana, a switch-hitter, does better from the left side of the plate, which is good since that is where he will get the majority of his at-bats. He hit nearly .300 versus right-handed pitchers last season. There is a little pop in his bat as he hit 38 extra-base hits last season including 21 doubles.
His fielding has made small improvements since he was a 17-year old shortstop in the Dominican Summer League. He had 13 errors in 35 games at that position in 2008. Last year, Santana had 18 errors over 85 games at shortstop so there is still work to be done on the defensive side of the ball.
Levi Michael: Usually, a first round pick wouldn't be too much of a surprise on a list like this but Michael is coming off a rough season. The Twins first pick in the 2011 draft was suppose to be a fast riser after his college experience at the University of North Carolina. He struggled in his first full season of professional ball.
Most of his offensive struggles came against right-handed pitchers. He only hit .212/.306/.271 over 288 at-bats versus righties. After posting a .216 batting average before the All-Star Game, he hit .272 down the stretch. He was able to make some adjustments and it showed on the field.
On the defensive side of the ball, Baseball America ranks him as the best defensive infielder in the Twins farm system. He split time between shortstop and second base last year and his path to the big leagues might come from his strong defense. Michael and Santana could form the middle infield duo for the Rock Cats.
Outfielders: There are plenty of eyes on the battle for center field in big league camp. Can Joe Benson or Aaron Hicks beat out the competition and win the Opening Day gig? Can Oswaldo Arcia find his way to The Show? But there is another other name in the organization to watch this year.
Daniel Ortiz: The 22-year old Oritz played at two different levels last season. Most of his playing time came with the Fort Myers Miracle but he did play a little with the Beloit Snappers. The former fourth round pick has been slowly working his way through the Twins system and he has made some improvements along the way.
After struggling to make constant contact in 2011 at Beloit, the Twins sent him back there to start last season. He gained some confidence and hit close to .300 in his 22 games with that club. When he was promoted to Fort Myers, his average dropped a little to .269 but he showed some power with 37 extra-base hits.
Ortiz can be used at all three outfield positions but most of his games in the minor leagues have been at a corner outfield spot. The Twins have plenty of other center fielders ahead of him so he will likely settle into a corner spot as he moves up the ladder.
