More reasons.
The Yankees starting staff is rested, and the Red Sox will have to use Tim Wakefield (who can go either way), and I'd imagine Derek Lowe who isn't the same pitcher on the road as he is at home. Pedro would go Game 3, and the Yankees have had is number in the past. Clemens never pitches well in Boston, so we'll see what happens.
The hitting advantage goes to the Yankees. Their starting to swing hot bats, and honestly I don't think the Red Sox are completley out of their hitting funk.
Yankees in 6. Too many factors in the Yankees favor.
