I agree with Shane. First, the farm system is plenty strong, and will be even after Buxton, Sano, and Meyer are in the big leagues. Second, if we flip Polanco, it should be in another year or two when we know what we have in Santana, Dozier (who is, let's face it, old for a 3rd-year player) and Gordon for that matter, and what we need to become a contender (catcher, defensive outfielder, fourth starter, etc.). Third, Polanco just came off a rough patch in AA, so now we would be trading at his nadir. Let's at least let him regress (upwards) to his ability. Fourth, in 2016 or 17, whenever Polanco gets to the big leagues, he'll have plenty of time to play. A utility infielder gets a lot of starts, and injuries happen. Polanco is also, by all accounts, a focused guy with great makeup, so I'm sure he can handle playing as a utility infielder and not playing every day until someone inevitably gets injured. The value of having Polanco rather than Nunez as our utility infielder (and a pinch hitter/runner) is significant. Escobar is more a trade candidate in my opinion, especially if he comes close to his performance last year.
