The D-Backs are only 3.5 games back in their division. Why would they be trading Vazquez?
They are more than likely interested in bullpen help from us, like Shingo or Vizcaino. Their bullpen is horrid and Shingo and Vizcaino would actually be improvements. Maybe we will get a couple prospects from them for one of our relievers and then package those relievers with some of ours for Schmidt?
