i don't think that he'sa potential amazing defensive shortstop; from what i've read, he has a good chance to be above average but not necessarily elite defensively. i'm excited about him, though, because he has good defensive tools and also makes excellent contact despite facing pitchers a few years older than him. he's got to be pretty raw, having played only one year of short-season ball coming into 2009, and despite this he shows good ability to make contact and hit breaking pitches. even if that power never comes along, if he can put the ball in play a lot and square it up well, he should hit for a good average, which combined with plus defense will make him a big-time asset. it also seems like he has great drive to improve and confidence in his ability. and on a side note, it's really nice that the cubs are developing some middle infield prospects from latin america. it seems like most other organizations at least have some slick-fielding weak-hitting prospects who project as utility infielders in the big leagues, but the cubs have been terrible at developing latin middle infielders forever.
