Which pitchers to start? WHIR

[tommo]

12 Team H2H Points League. I have to pick 5 of the following 8 pitchers. This week's match-ups:
Weaver - @BOS, CLE
Marcum - @ATL
Scherzer - NYY
McClellan - FLA, MIL
Chacin - @ARI
Danks - MIN
J. Garcia - MIL
Hellickson - TOR

I currently have Weaver, Oswalt, Marcum, Scherzer, and McClellan set as my starters. Everything I am reading says Oswalt is set to start this Saturday in Atlanta. I'm not sure if he's a good play considering he's been away from the team and probably has a lot on his mind. What do you guys think?
