A player is one of the best prospects in baseball if he dominates AAA at 22 ... AA at 21 ... A+ at 20.
Slugging >600 in A ball at 19, as a middle infielder, is a dominating performance the first month.
Zduriencik will be glad if and when he ever gets some help out of his own system, so he doesn't have to quilt his team together out of >27-year-old players.
