I wouldn’t be opposed to just reseeding once the playoff start, even if you keep the division winner in the playoffs. And Houston would be in even if you just went top-6.
Rays and Yankees should have byes, Yankees should get the winner of Bos-Hou and TB would get Cle-ChW. Bos and Cle host WC series.
interesting enough, the NL wouldn’t change at all if you took top-6.
