The Diamondbacks took five players ? Stephen Drew, Mark Reynolds, Max Scherzer, Justin Upton and Chris Young ? out of all discussions for Dan Haren, yet the A?s still were interested enough in Arizona?s deep base of young talent that the two sides are talking seriously. The D?backs are so deep that reliever Tony Pena and first baseman Conor Jackson also are not part of these talks. Outfield prospect Carlos Gonzalez would be a central piece should there be a deal.
