It seems the current Cubs regime is intent on building with young bats. This marks yet another acquisition by them of a talented infielder (La Stella) in return for a talented pitcher (Vizcaino). That said, Chicago now has a super-glut of potential starting middle infielders. La Stella probably has the tools and plate patience to start for stretches in the majors, but he'll clearly be stuck behind rising star Baez at second base. Meanwhile the Cubs still have star Castro at shortstop (along with top prospect Russell and outfielder Alcantara can play the keystone spot too). It does give new manager Joe Maddon copious options at important positions, although the Cubs lose some ability to sign international players with the bonus slot part of the deal.

Atlanta's No. 1 prospect is speedy second baseman Peraza and it's clear the Braves think he might be close to ready. By moving La Stella here they clear the way for Peraza, and if Peraza's not quite ready yet they have veteran Pena to hold down second base. Meanwhile the Braves get a gifted power arm in Vizcaino, who had some tough injury woes in '12 and '13 but now looks back to high-velocity form. Expect Vizcaino to soon replace the recently-moved Walden as a top young arm backing up closer Kimbrel in the Atlanta 'pen. The added international bonus slots give the Braves increased flexibility to ink international players.

La Stella's already-limited fantasy appeal takes a minor hit here, since he looks unlikely to push for many starts in Chicago's gifted young infield. That said, he has the offensive tools to be a good utility guy. Vizcaino similarly doesn't see much change fantasy-wise, since it would probably take several key injuries in Atlanta's bullpen to earn him a shot at significant fantasy numbers anytime soon.
