The Rockies have been playing really well of late, but its going to be real hard for them to win it because the Padres have been playing even better then the Rockies, and the D-Backs are really strong as well. The Rockies are 4.5 games back of the Padres, so they'll need to keep winning and the Padres need to start losing which seems unlikely. Personally I dont think they'll win it.
Right now as much as I don't want to admit it I think they are done. But they have to be given props. These guys were given no chance at all and even during the season people said they won't even come close and I think they showed they have a lot of ability and hell it's not over yet.
