For the St. Louis Cardinals, that means their swing into Denver, where they'll play the Colorado Rockies for three games starting Monday in the Coors Field altitude. The Cardinals, after beating the San Francisco Giants twice to secure a weekend series split, are just a game out of the second wild-card spot in the NL, which currently belongs to S.F. With the Giants starting a series against the Los Angeles Dodgers, there's opportunity in front of the Cardinals. Rattle off a few wins against the third-place Rockies, hope the Giants can't do the same against the Dodgers, and St. Louis could be sitting in a much better playoff position when it hops on a plane again.
