SF needing offense and set-up guys

[Marlins]

I think I am finally done tinkering with my rotation, but it's left my lineup and pen hurting. Looking to deal some of my prospects (yes, I know I got nothing special) for a bit of an upgrade in lineup or pen. Below is my line-up and pen where I would be looking for upgrades over:

1B: Kotchman/Glaus platoon
2B: Hill
3B: Rolen
SS: Rollins
LF: Hermida
CF: Victorino
RF: Rios

Pen
Byrdak
Crain
Gregg
Howry
Nelson
Pinto
Rauch

PM me with any ideas.
