The division races are more or less over in the AL, though Seattle could still mathematically catch Houston. However, with about 1 week to go, the WC race will be exciting and nerve-racking. An advantage to the Red Sox is the head to head games between the Yankees and the Jays and between the Mariners and the As.
In the NL, the WC race is more or less over, though there are still a couple of division races going on. The NL East race is the one carrying the most significance because whoever doesn't win the division goes home.
Go Red Sox! Go baseball!
