Hamilton wins it because he's been valuable at both LF and CF. And has played less games and his team is going to the play offs etc etc. Bautista will probably surprise with how many votes he gets.
3. About 10 others
This is going to be one where the old-timey guys just look at the win column. It sucks because I think Lester has been twice the pitcher CC has this year. Cahill will (undeservedly) be top 5.
And now for the B Grade awards
If the Rockies somehow squeak into the play offs this should be very close. I think Votto wins because Cargon's "Coors Monster" reputation should cost him a few votes. And because his defense has been below-average.
Unless Halladay is arrested as a sex offender in the next two weeks, this is his by a street. Josh Johnson and Ubaldo (in more enlightened circumstances) would be right there with him, but they probably won't even get close.
