Who the hell is Nolan Arenado?

Unless you're a die hard fan of the Colorado Rockies or the PA announcer for the Salt River Rafters you may not be familiar with Nolan Arenado.  The 20 year old third baseman in the Rockies minor league system just completed a stellar Arizona Fall League season for the aforementioned Rafters.  Arenado clubbed six homers and drove in 33 in just 29 AFL games.  He wasn't too shabby in the regular season either as he hit 20  bombs and knocked in 122 runs for Modesto of the California League.  The Rockies are apparently so impressed with Arenado that he may be in line for the big club's third base job in 2012.  Despite Arenado never playing above A-ball Colorado seems to be clearing the deck for the kid.  Ty Wigginton was dealt to Philly a few weeks ago and Ian Stewart is rumored to be either non-tendered or traded.  Come opening day in Denver several thousand Rockies fans may be asking "Who the hell is Nolan Arenado?"
