Santana outplayed everyone's expectations after the unheralded rookie was called up to the big leagues last year. The 24-year-old Dominican led the Twins with a .319 batting average, flashed a little power with seven home runs, and held down center field — a position he had never played before — when super prospect Aaron Hicks struggled once again. His speed and effortless athleticism made what should've been an ugly transition look easy. This year he's pegged to move back to shortstop, a position the Twins haven't had consistency at since the Christian Guzman days. If he can hold that down, watch Target Field start filling up with #39 jerseys.
