LH relief for RH relief

[Cardinals]

I have three pretty good lefty relievers now in Sean Burnett, Tony Watson and Marc Rzepczynski. I'd like to deal one of them for a right handed reliever.

I also still have Matt Holliday on the block. Willing to get creative there. Holliday projects at .281/.365/.473. The .365 OBP is the 14th-best in ZiPS, and his OPS+ is 19th-best.

Also available:
Ervin Santana
Luke Hochevar
Jake Westbrook
All prospects are available too, but with guys like Holmes, Piscotty, Sanchez, Gallo, I'll need more than relief help.
