Because MLB had to add games at the end of the year to make up the first week, St. Louis hosts Pittsburgh for 3 then travels to Pittsburgh for 3.
St. Louis has the division in hand, up 8 with Milwaukee at an elimination number of 8. Maybe seeding could be at hand Atlanta, or maybe even New York? I don't know, seems like the chances are slim. I guess wat I am getting at is that the final 6 games of the season shouldn't make or break anything for St. Louis or anyone else.
