If nothing else, the 2015 season is turning into the year of the Yankees prospect. So far we have seen Jacob Lindgren, Slade Heathcott, and Ramon Flores make their MLB debuts and it looks like we'll be adding at least one more name to that list as Mason Williams is the next to get the call. After placing Andrew Miller on the disabled list, New York could have technically recalled outfielder Ramon Flores because he would be replacing an injured player on the roster, but instead they decided to go with Mason and Chris Martin.
