Red Sox tied with the Yankees 2-2 in the ALCS
Cubs lead with the Marlins 3-2 in the NLCS
The odds are descent that this might actually happen now that the Red Sox have managed to pull even once more. However, they will have to win a couple at Yankee stadium.
On a side note, apparently Michael Bolton sang the national anthem to open the game, but after he got to "and the ramparts we watched," he forgot the lyrics, and the grandstand had to sing him through. I'm hoping video of this pops up somewhere.
