Danny Knobler of CBSSports.com hears that some think the Diamondbacks could trade Jason Kubel as soon as Tuesday. Ken Rosenthal of FOXSports.com reported early Tuesday that the D-Backs were discussing trade scenarios involving Kubel. Moving him would leave Arizona with a starting outfield of Gerardo Parra, Adam Eaton and Justin Upton from left to right. Of course, the Diamondbacks are also talking to teams about Upton right now.
