Frequently, you read that Correa reminds scouts of a young Alex Rodriguez.  A-Rod is listed at 6-3, 225, and he was an outstanding fielder at shortstop.   If Correa is fortunate enough to have a long career, he could be like Ripkin and A-Rod, playing shortstop in the early part of his career and switching to 3d base later.  Machado was moved to 3d base because J.J. Hardy was already providing good shortstop play when he was called up, and there was a vacancy at 3d base.
