Why would anyone think this kid is good enough to play for the Cubs right now? He hasn't hit a home run above A ball, has 31 games of experience above A-ball and didn't exactly set the world on fire with his defense in 2009 ( 39 errors total, .950 in Double-A, .933 in High-A). Don't get me wrong, Castro is going to be a good player, but he needs to start the season in the minors, preferably in Double-A where he can take advantage of the warmer weather..put up great numbers there and move up to Triple-A.
