There are only eight players born in 1991 who make my top 80 list, but the range is from a player in AA who could be a Twin at some point in 2014 and two guys who could return to rookie ball at the beginning of the season.

4. Eddie Rosario, 2B, RH, DOB: 9/28/91

2013 A+/AA (combined stats): 544 plate appearances, .302/.350/.460 (.810) (.867 career), 32 doubles, 8 triples, 10 homers, 38 walks, 96 strikeouts, 10 stolen bases, 10 times caught stealing.

Rosario dominated the FSL and earned the promotion to New Britain. He held his own for the most part, but there was a significant drop in production for the converted second baseman. This is mostly due to a decrease in power numbers and a big uptick in his strikeout rate, so this is a fairly normal bout of growing pains. Defensively, Rosario is now comfortable and may even excel as a defensive second baseman. Of course this comes at a time when the Twins are actually currently short on outfielders and not on second baseman at the top of the system. Rosario should be headed back to start the year at New Britain before a mid-season promotion to Rochester. A September call-up is almost certainly bound to happen if he doesn't force the issue earlier.

39. Levi Michael, SS/2B, SH, DOB: 2/9/91

2013 A+: 375, .229/.331/.340 (.670) (.659), 15-4-4, 49-67, 21-2

Michael has now fallen from around the 20-25 range on my list to 39, and much of his continued presence in the top half of this list has to do with the hope that, when fully healthy, Michael can build upon minute improvements made so far and emerge as a legitimate prospect. His stolen base numbers were impressive this year, but not much else is, including his defense. Even though he hasn't really earned the promotion, the time has likely come to push Michael to New Britain to see if he can get on track.

35. Adrian Salcedo, RHP, DOB: 2/5/91

2013 A+: 58.1 innings, 3.70 ERA, 54 strikeouts, 15 walks (7.2/1.8 career)

Salcedo will be 23 on opening day 2014 and he will likely be in New Britain. That isn't far off from the projection in 2009 and 2010 when Salcedo showed great promise. 2011 was a down year for the most part, and 2012 was a disaster with an injury. Salcedo was very effective in the bullpen in Fort Myers this year. The key question is whether or not the Twins view him as a starter or not. I honestly do not think so, and I believe he should be at the back end of the New Britain bullpen for 2014. Salcedo has appeared to right himself and this year is going to be huge for him.
