To anyone being objective about this, I think it has FAR more to do with the fact that we're already loaded at short than it does his numbers at AA.
Hardy is outstanding with the glove, and has good pop in his bat (great for a short-stop, relatively), and is under 30.
Andino's natural position is short-stop... I just realized the abbreviation for this position is a dirty word in here, so I'm tortured to having to type the word in it's entirety. Great word filters in here *sarcasm intended*...
This makes Machado far more expendable than a prospect of his caliber would be otherwise. It would be myopic to just say "he's off the table", flat out, and not consider an offer for him if it could get us a top-tier, "proven" player at a position of need (3B, ace righty). And if we don't pull the trigger now and he flounders in the minors for another year (or two), the value will be gone. And this team is in a position to contend/win NOW, who knows where it will be 3-4 years from now when Machado is ML ready. And even then, will he be a better option than a guy with Gold Glover caliber defensive skills and 30 HR/season pop?... probably not. Only if he becomes the "A-Rod clone" we all desperately hope he can be. And what are the odds of that?... quite slim. So if we can get a proven, top tier player for him right now, to me the pot odds (poker players know of what I speak) are heavily in favor of taking it.
I couldn't care less if he was hitting .350 right now in AA instead of .250. Well, I'd only care because it would increase his value.
I hope DD is not as short sighted as the posters in here as well...
