2B. Chase Utley
3B. Evan Longoria
SS. Ryan Theriot
CI. Scott Rolen
MI. Freddy Sanchez
IF. Mark Reynolds
OF. Michael Bourn, Austin Kearns, Curtis Granderson
Util. Randy Winn
Bench. Reed Johnson, Joe Crede

SP. Scott Kazmir, Sidney Ponson
RP. Chad Gaudin, Chad Durbin, Tom Gordon, Russ Springer, John Grabow
DL. John Smoltz, Rafael Soriano, John Lackey

I am currently 9th out of 20. 6 teams make the playoffs and I am trying to give up on starting pitching but nobody will accept a trade with Lackey and Kazmir, who should I aim for in trading those two?
(I would drop Ponson if I can trade Lackey and Kazmir)
