In the 2004 and 2007 deciding games of the ALCS, the Red Sox, having changed the momentum of their series a few games before, won big. In 2004 against the Yankees, after winning several close games, they won Game 7 10-3. In 2007, they won Game 7 against the Indians 11-2.
I expect the Red Sox will win tonight by at least 6 runs, the momentum still swinging in their direction.
