What is sad is the Nats could not come up with a better trade offer for Marlon Byrd than a DFA'd, out of options guy who has had no success in the majors and a PTBNL. What that says to me is that Rizzo is not interested in an offensive upgrade at this point in the season. I don't think it is hard to imagine the Nats being able to beat that offer, and a righty CF / LF bat to match with Bernie and Ankiel would seem like a need.
JCA - this shouldn't shock you. See the Michael Bourn trade for reference.
