10. Carlos Perez, Angels
Carlos Perez definitely checks in as a very bold player on this list, but also comes with a lot of promise and potential. Despite backing up Chris Iannetta the majority of last year, the young Venezuelan made appearances in 86 games slashing a respectable .250/.299/.346 in his rookie year. He also drove in 21 runs, with 13 doubles. Defensively, he limited himself to only seven passed balls and threw out nearly 38-percent of runners who tried stealing against him. With the aforementioned Chris Iannetta moving on to Seattle, the 25-year-old Perez will likely compete with former NL Rookie of the Year Geovany Soto for playing time, and the youngster has a good chance to win.
