Well, the World Series never used to push into November either, and with TV in charge, it may someday become "The Winter Classic".
It has only gone into November once, but that was in 2001, and the reasons for the season being suspended for a week were obvious. November baseball becoming standard is something I might see happening if the Division Series gets expanded someday to 7 games. A future commish might do that; probably not Bud.
As for now, they might not need Games 6 or 7, as the Phils can still wrap it up whenever they play. Hamels coming out, assuming he does, probably works to the Rays’ advantage though. I think Selig and the top brass are hoping Philly just gets it over with tomorrow night.
