Not fair for a WC team to possibly finish with a significantly better record, than 1 or even 2 division title winners in a league, then face off vs another WC-winning team in a one-shot postseason game. Their WC opponent could conceivably ALSO have a better season record than 1 or 2 division title winners as well.
So IMO, MLB should reduce the regular season by 5-8 games, and allow for @ least a best 2 out of 3 WC round in each league.The regular season once was 154 games in length anyway. In some northern cities, the WS has been been played in downright nippy temps by late October. I remember how chilly that it was in Detroit, on the night that Maggs hit his pennant-winning walkoff 3 run homer vs the A's in '06. I also remember trick or treating as a kid on some Halloween nights, when a sweater or even a coat was needed underneath my costume.
