Your pitching has a very good balance. Kudos on that.
As far as the hitting, I don't see anyone in your lineup who has the potential to steal 30 or more bases. Damon might, but his recent numbers seem to indicate otherwise.
If I were you, try to package Affeldt and a closer to get a guy like Sanchez, Dave Roberts, or Corey Patterson or you can pick up a guy like Luis Matos, Brian Roberts, or D'Angelo Jimenez off the waiver wire.
I never smile if I can help it.... Showing one's teeth is a submission signal in primates. When someone smiles at me, all I see is a chimpanzee begging for its life.
