My stance on the extra innings runner has already been stated multiple times, but I will say it is really strange to suddenly play under different rules during the postseason. If the extra innings runner is how baseball is going to be played now, then it should probably apply in the postseason too. But I will hate it until the day I die. I still hope that MLB will eventually go back to the old rules for regular season games too, but that hope is fading. Eh, the OT rules in the NHL change between the season and post-season. Doesn't bother me in the slightest
