I don't think there's much there with Gyorko, to be honest.
Derek Dietrich is a free agent second baseman who is a year young, has better career stats, and has just as clear a shot at playing time. Better projections too. Literally the only difference is the distribution of their past production. Because Gyorko's was all concentrated in one season (a fairly arbitrary collection of 182 days), he has a better reputation. Everyone who wanted to give up a second rounder for Gyorko should go rush to grab Dietrich.
