I think the Braves are in free fall now. Their ace got jacked up last night by the Nats, and I think that the Phillies series might have just crushed them. Their saving grace, however, is that no one seems to want to win the West. They may just sneak in, as Nahste said in the NL East thread, by the skin of their dicks.
Personally, I think the Giants and Padres will both get in, both by small margins depending on the manner. I don't think that the Rockies have the pitching to make the push, and this 5 game losing streak their in isn't helping. It's a semi-exciting race nonetheless, even if I don't think any of the 3-4 teams in contention are that good.
