Alcantara realized his potential in 2013, which is exciting going into the 2014 season.
Probably the most well-known player on this list, Arismendy Alcantara is a player who is on the verge of making an impact with the Cubs right now. Due to the club's desperate need of offensive production at second base, if he can blow officials away in spring training, making the Opening Day roster isn't out of the realm of possibility.
Making the big league team out of camp will be tough, given that he has never played at the Triple-A level, but he has methodically worked his way through the minor leagues in the Epstein-Hoyer model of player development.
In 2010, Alcantara played his entire season at the low-A level. The next year he played his entire season at A-ball; in 2012 he played his entire season at high-A; and last season he played the entire year for the Double-A affiliate of the Cubs, the Tennessee Smokies.
After playing on all those different levels of minor league competition, Alcantara took a huge step forward last season in Tennessee. While he only batted .271, he hit 15 home runs and drove in 69 while stealing 31 bases. That's a pretty solid No. 2 hitter in the major leagues.
In reality, translating those numbers to the big leagues will be a challenge for him. For someone without huge power upside, he strikes out a lot. Last season in Double-A, he struck out 125 times in 494 at-bats. He will have to put the bat on the ball more consistently this spring and into 2014 to convince the Cubs front office that he can make a difference going forward.
While Alcantara is the No. 4 second base prospect in baseball, according to MLB.com, he still isn't talked about nearly as much as some of the other top prospects in the organization. For that reason, he is the top sleeper in a long line of Cubs prospects.
