Mr.B what did your pitchers do? Did they make an adjustment and start with two feet on the rubber?
I think it's minimizing what was being asked to call it an "adjustment." This is a major change to force pitchers to make on the spot. It's not actually reasonable to force them all to do this.
I think both teams should've agreed to not play the game until the umpire was clear on the rules and agreed to call them properly. Forcing pitchers to do something mechanically different like this is putting them at risk physically.
I don't know why guys like this ump. They're not interested in knowing the rules. They never have good attitudes. They're certainly not getting paid enough to make it worthwhile. It really seems like they only thing they get out of it is the power trip. There have got to be easier ways to ruin everyone's day.
