I've got a question, why do they want to trade Wagner? The guy is 22 years old and he's going to be a future closer! Why not let the kid develop?? But anywho, Dunn will be another Bellhorn to the Sox if they bring him in, and instead of seeing K or double like they do with Bellhorn (more like 14 K's to every double), we'll see K or HR with Dunn. I would try to get either a Sean Casey who's an OBP machine or Huff and offer Shoppach.
There is such a thing called clutch and David Ortiz is the modern day definition of it
