Yankees favorites to land Diamondbacks' Dan Haren

UPDATE: 12:50 AM: Jayson Stark is now reporting that the Yankees and Diamondbacks were "never close" to a deal involving Haren. There is a disagreement over whether the package the Yankees send should involve all prospects or MLB ready players.

FOXSports.com is reporting that the Yankees are the favorites to land Diamondbacks starting pitcher Dan Haren. The Diamondbacks have made Haren available to trade and are having ongoing negotiations to move him. Haren is 7-8 this season with a 4.60 ERA, but he posted a season-best 3.19 ERA in the month of June. 

Haren is set to make 25.5 million dollars over the next two seasons, with a 15.5 million dollar club option for 2013. 

The Yankees would certainly have to surrender a top pitching prospect to land Haren, but what else would it cost? One pitcher that surfaced in the Cliff Lee talks was Zach McAllister, whose father happens to work for the Diamondbacks as a scouting supervisor.
