He may deserve it but, from what I understand, it's already voted on by the writers when the series ends and postseason play has no influence on it.
Plus, the same arguments apply to him as they did against Beckett in 07: higher ERA, way more run support (more than 3 runs per start). Greinke should get by a long shot. Plus, Felix was equal on wins as See.See., and had a much lower ERA (2.49) Heck, I would take Halladay before CC too. Here are the ERA leaders for the AL this season. Here are some more stats from ESPN. Jon Lester had 2 more Quality Starts than CC, even with 2 fewer starts total, and a pretty damn bad start to the season.
