Tracy would have to play third there which he was never great at and with his injuries he'd likely be even worse, why would the Yankees want him? Furthermore what do you want in return from the Yankees thats realistic? Im not sure what the Yankees farm system is like, but the D'backs outfield is crowded and set, their starting pitching is terrific, the infield seems set, etc. You wanting to move Tracy for bullpen pieces or something?
I think the D'backs are likely set with their roster and just have to hope that guys like Upton, Reynolds, Young and Drew can continue to grow and have one or two of them blow up and have huge years.
