If the Cardinals lost the rest of their games this season and Houston won the rest of their games this season, the two teams would be tied. Since the Cardinals won the season series against Houston, the Cardinals would win the tie-breaker. So, technically, their magic number is one, but they’ve essentially won the National League Central Division for 2005.

If they win one more game or Houston loses one more game, they will have “officially” clinched the Central Division. Go Cards!
