He has overcome every challenge the org has given him since he was 17. He forced their hand in making him their 3B last season (by simply being better than the alternatives, both in house and via trade). I'm betting on the kid.
Best option for a bat is to revisit the Abreu trade to see if there is something reasonable - and then look at Santana for a high floor, meh ceiling one. Or Hosmer for the real boom/bust one.
