Let me piece my playoff picture together here:
Phillies vs. Brewers ------> Brewers (Pat Burrell doesn't keep it up)
Cubs vs. Diamondbacks --> Diamondbacks (Cubs don't get Burnett, lose rematch from yast year)
Diamondbacks OVER Brewers (Webb, Haren dominate the series)
Red Sox vs. White Sox --> Red Sox (Quentin dies off & Dye somehow gets injured)
Angels vs. Tigers --> Tigers (Saunders, Lackey keep it close)
Red Sox OVER Tigers (Schilling leads this team with teamwork speech)
Diamondbacks OVER Red Sox (Haren, Webb, Johnson keep the Red Sox offense on tilt)
To answer the question: I'm going with the D'Backs.
