Are The Astros Done?

What are the Astros doing? They gave up a 7 game lead to the Rangers. The young Houston Astros, were 4th in runs batted in up till the all star break. In August they were 25th and in September they were 16th. Now they are second in the Wild Card on 1.5 games ahead on the Twins. Will the young players be able to make a turn around and keep being in the playoff picture? What team will take advantage of the mistakes of the Astors?
