I'm probably in the minority on this one, but none of the above.
Seth Cormier (81, 74, 58, 57) is your current 2B. Play him in CF; he's got the second-best range of the 4 and you won't be wasting Servet's arm out there. Then it's Servet at SS, Galvez at 2B (where he can handle a lot of chances cleanly with that 91 glove) and Arias at 3B.
