MLB should revoke the championship the Astros won in 2017 and have a best of 7 between the Dodgers and Yankees before the 2020 regular season starts. They could bring back the 2017 postseason rosters of each time. The winner would be declared the 2017 World Series champions.
The 2018 ALCS was between Astros and Red Sox. If they both cheated there'd be no team to represent the AL.
Best not to do it for 18 since there'd be no AL team. 17 there's a simple solution, as presented in the OP.
um, I dunno sabre cheating on a grand fucking scale for starters and if you think only the Stro's did it, wake up rampant cheating throughtout bottom tier umping, poor team and league oversight etc
My only real disappointment is how much more the bullpen is used. There's something great about watching a starter go 7+ innings.
