In spite of the fake fan noise the sound of the ball hitting the bat or the catcher's mitt has a much sharper sound than when people are in the stands.
This season is a giant asterisk anyway so from that standpoint I have come to the realization that I don't care that the postseason is a sham. I guess I'm in favor of having a few more Twins games to watch so whatever.
If that's the argument then don't even play the games. Just advance the higher-seeded team. And again in the next round. And so on. Just award the championship to the team with the best record.
That's true in theory but that's not true in baseball. All it takes for a bad team to win two games against a good team is for one mediocre pitcher to have a good day and one good pitcher to make a mistake.
