I don't think there is much reason to think that would happen. We don't see evidence of that in the regular season as Scherzer's career record is 190-97. We don't see evidence of that in the postseason when even the best teams will generally lose a few games. And we don't see evidence of that in baseball history when in the past a team's best pitcher might start up to half of that team's games. Randomness is just inherent to the game of baseball.
