Pitcher Help!! Please fix my roster

[bklik]

Ok, I believe I have my batters doing well, but my pitching somewhat worries me. 5x5 roto scoring system. Start 7 pitchers. Heres where they lie as of right now.

SP J. Peavy (SD - SP)
SP E. Bedard (Bal - SP)
RP F. Rodney (Det - RP)
RP F. Liriano (Min - SP,RP)
P B. Sheets (Mil - SP)
P C. Young (SD - SP)
P J. Putz (Sea - RP)
BN M. Batista (Ari - SP,RP)
BN J. Patterson (Was - SP)
BN B. Myers (Phi - SP)
BN A. Burnett (Tor - SP)
DL N. Lowry (SF-SP)

Who should my starters be out of this lineup? I also need to drop somebody when Lowry comes off of the DL, who should that be? My teams needs a closer, any ideas of who to deal for a closer of equal value? Thanks for all the help guys!
