"Don't swing on a 3-0 count in a blowout" has to be one of the dumbest unwritten rules to me because it helps a pitcher get outs if he's struggling to throw strikes. Even if it doesn't help the pitcher, it's still ridiculous to say a batter needs to give the pitcher a free pitch. If the Twins wanted the White Sox to stop playing, they should have forfeited. Baseball is better because he put that 45mph pitch into orbit.Good he deserved it. Up 16-4, in the 9th, and you are swinging at a 3-0 pitch. Hit him every time he comes up. Take the 3-0 strike then do what you want.
MLB should just put in a mercy rule if we're that concerned about the fragile egos of players.
