It would appear that the Yankees have somewhat of an abundance of catchers at the moment. Brian McCann and one of Francisco Cervelli, Austin Romine, or J.R. Murphy will be on the big league team, but with Gary Sanchez in Double-A, there's only room for one player in Triple-A. Unfortunately, while they have wealth at one position, they also have a dearth in several others. Derek Jeter is retiring and Brian Roberts is going to break, so they could use an infielder or two.
Cervelli is the likely candidate to win the backup job, so if the Yankees want to trade what they have for what they need, they might look to deal one of Romine or Murphy. If that's what they have to give, then the Diamondbacks might be a perfect fit. They are said to be looking for a young MLB-ready catcher to play behind starter Miguel Montero and that they would be willing to trade one of their shortstops, Didi Gregorius or Chris Owings, to get what they want.
It's like the Diamondbacks are specifically talking to them because I can't think of another team who has what they are looking for and also needs what they have. Gregorius, 24, hit .252/.332/.373 while playing just slightly under league-average defense at short in his first full season. Owings, 22, one of Arizona's top prospects, hit .291/.361/.382 in his first taste of the majors, splitting time between short and second base in just 20 games. While Gregorius might be had in a one-for-one swap for Murphy, Owings would take a little more to pry free. It's believed that either one would fill in at second base until Derek Jeter retires and then could replace the Captain in 2015.
The Chicago White Sox have previously scouted J.R. Murphy as well, so it's clear that the Yankees have what teams want. Now that Robinson Cano has gone, Jeter is retiring, and no one seems ready to replace them, it would make a lot of sense for the Yankees to try and find a young player who can fit in as a longterm option.
