Forget the ump. Stammen had to make that pitch.
He made the pitch, the strike three pitch before the home run. You can't let the umpire off the hook for that call and then the strike three call to Nick( that wasn't), that he actually waited three seconds before calling.
It perpetuates the feeling of the team being a loser through the actions of the umpire, ie Major League Baseball because the ump represents the league.
