Eury Perez

The young speedster got his first taste of the majors in 2012 and swiped three bases after stealing 51 between Double-A and Triple-A. He still needs to learn to control the strike zone better if he wants to be anything more than a fourth outfielder in the long run, but it would not take too much improvement on that front for a Michael Bourn-like career path to become a realistic possibility.

Every organization has a minor league speedster who makes fantasy owners drool with his steal totals, and for the Nationals that player is Perez, who went 64-for-77 on the basepaths at Low-A in 2010. His game still needs a lot of refinement, both in terms of his patience at the plate and his route-running in center field, but with Nyjer Morgan looking less like a long-term answer than he did this time last year there's an opportunity for Perez to move up quickly if he smooths out the rough edges in his game.
