Will the Mets Blow it? How 'bout 'dem Red Sox?

Three teams in the race and only two will move onto the playoffs. I just listened to some dude on Sports Center and he's confused me more with his 12-billion scenarios. From what I gather... it's close. Someone just let me know who makes it.

The Reds Sox - Yankees race however I understand much better! Yankees are down two games with three to go. Well, either way they'll both make the playoffs so does it really matter who comes on top for the league?

Is it Sunday yet???
