While the Yankees farm system is loaded, there is no guarantee which, if any, prospects will work out. Many of them, like Jorge Mateo and Clint Frazier, have plenty of potential. That plus five dollars will get you a grande mocha latte at Starbucks. But it will not get you even one hit in the MLB.
Aaron Judge, however, is what is called a Prospect Plus: a player with one overwhelming aspect to his talent. For Judge, it is his power potential. He can guess wrong on a pitch and still swat it 400 feet.
