Your hitting's pretty solid. I don't see any need to change anything there.
As for pitching, the only change I would make is dropping Lilly. He's too inconsistent to take up a roster spot.
Other than that, it looks good.
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.
