As a baseball purist, I HATE the playoffs and firmly believe the best records should go to the show (it should have been the Sox and the Cards). Given that the Sox qualify for that and the 'Stros got there through a backdoor wildcard, I hope the Sox win it all..
The teams don't play the same competition, so that's hardly adequate. Else you might as well just declare the team with the best record in either league the champion and junk the postseason entirely.
