I have no idea how the Rockies are doing it, but it wouldn't surprise me in the least to make another run to the World Series. The Cardinals, Dodgers, and Phillies are kind of limping down the stretch, but then the Cards weren't exactly setting the world on fire in September back in 2006 either.
The Yankees should get there as well, but would it really surprise anyone if they choked again in the playoffs?
Naturally I'd love for the Cardinals to win it all, and I love the top of their rotation and the meat of their order, but their bullpen is a big ole pile of crap. Carpenter & Wainwright better go extra deep in their games.
