How can I upgrade my staff???WHIR

[CDAG02]

Looking to upgrade my pitching staff with a solid SP. What could I expect to get for Victorino + one of my pitchers (Joba, Shields, Harang, Weaver, Meche)? Or could I get somebody for Victorino alone? I'm really wanting to get rid of Joba with the uncertainty surrounding him going to the bullpen or staying in the rotation, so I'm looking to package him with somebody for an upgrade. Thoughts?
