My pitching staff:

SP Freddy Garcia
SP Mike Mussina
SP Jamie Moyer
SP Joel Pineiro
SP Adam Eaton
SP Jon Lieber
RP Armando Benitez
RP Octavio Dotel
RP Arthur Rhodes
DL A.J. Burnett

I really want to pick up SP Wilson Alvarez off the free agent list. In order to do that I have to drop one of these pitchers. Which one should I drop? I was thinking it should be Adam Eaton, who has struggled in his last couple starts, but am not sure. I might have chosen Pineiro before his last start in which he was starting to look like the pitcher he was last year. What are your thoughts?
