I didn't realize this earlier, but one of the most significant factors in this series is the handedness of the Tiger rotation. 4 right handed pitchers.
The Red Sox have an .820 OPS against righties and a .750 OPS against lefties. Was anyone expecting Nava to have a line of .322/.411/.484/.894 against RHP this season? . .411, what a monster OBP against righties. http://espn.go.com/mlb/team/stats/batting/_/name/bos/seasontype/2/cat/OPS/split/32/boston-red-sox
With the exception of Middlebrooks, the entire lineup has crushed right handed pitching with OBPs averaging in the .370's and bottoming out at .340. Not only that, having 4 straight righties lets some of the platoon guys be more comfortable with their roles, and gives Farrell a much easier decision managing each game. It does makes me seriously question the decision to leave Ryan Lavarnway off the playoff roster however.
