Slade Heathcott is 22-year old. And, Mason Williams is 21-years old. To date, neither of them has played a single game at the Double-A level (or higher).
Adam Jones was playing as a full-time and productive player in the major leagues when he was 22-years old. Ditto on Andrew McCutchen, Carlos Beltran and Grady Sizemore. Heck, guys like Ken Griffey, Giancarlo Stanton, Justin Upton and Rocco Baldelli were excelling in the big leagues as full-time regulars at the age of 21.
Unless Heathcott and Williams come fast this year – and, they just may do that – we shouldn’t consider them as all-stars in the making, yet.
The fact that they haven’t sniffed Double-A yet at their age is a flag. Let them play there and master it – and then get their feet wet in Triple-A. If that all happens this season, then Yankees fans can get excited about these two players.
