Replacing Blake Swihart atop the list is the Cubs' Willson Contreras, a converted catcher coming off a breakout campaign in Double-A, while Yankees slugger Gary Sanchez re-enters at No. 2 after not making the list a year ago. Beyond those two, though, the group features mostly younger talents who are years away from making an impact in the Major Leagues.
