Wouldn't this present some serious logistical problems? Look at this year: had the Mets won last night, they'd have home-field advantage due to a better record. But the Cards did, so according to your suggestion the Tigers would get it. That gives Detroit all of two days to prepare the stadium, or Shea two days if the Mets had won. The grounds crew etc. would have to be completely on call, not to mention ticket sales would be a mess. And the Tigers wouldn't have known until late last night whether they were staying put or traveling. I think they definitely have to know who has home-field advantage before the postseason begins.
