The Diamondbacks are in the process of trading right-hander Dan Haren, according to ESPN's Buster Olney. "Heard this: The D-Backs are in the process of exchanging names on Dan Haren. I don't know if any team is necessarily deeper ... whether a Haren deal can be made, because the D-Backs will need a big-time haul in return for the All-Star pitcher," Olney wrote on his Twitter page Thursday afternoon.
