Should i trade freddie freeman and lance berkman for cc sabathia and jimmy rollins?

i have jeter who is my only shortstop on the dl and rollins can fill in until jeter gets back..i really need pitching cause i am behind in all pitching catorgies...only problem is that if i get rid of berkman and freeman i will have to play my only 1st baseman i have left in adam dunn everyday..what do you all think
