Luis Guillorme - if The defensive specialist had a surprisingly effective performance at the plate in the Eastern League, going .283 / .376 / .331 // .706, with one homer and 46 RBI. They've already moved him off shortstop 50% of the time, so they seem to be fast-tracking him, seeing him as at least a potential utility infielder in the near future. David Thompson - 3b His .263 / .325 / .429 // .754 line kind of hides his knack for piling up RBI. The 2015 fourth rounder has moved up fast and met the challenges, so ... Arizona! Kevin Kaczmarski - of A surprise pick among the organization's soggy outfield talent pool, Kacz went .274 / .370 / .369 // .739 in AA after only 42 games for St. Lucie.
