And, so, I believe that all of the following possibilities still exist for the Astros:
1. Tie for division crown (Rangers lose tomorrow and Astros win both remaining)
2. Host wild card game (Yankees lose both remaining and Astros win both remaining and Rangers win tomorrow)
3. Astros travel to NY for wild card game (Yankees win at least one game and (Astros win only one game or Angels lose tomorrow))
4. Astros not in playoffs (Astros lose both remaining games and Angels win tomorrow)
That's pretty remarkable.
ETA: I have no idea what would happen if they actually tied with the Rangers.
