I also had BOO of order yesterday, and it was the offensive team that pointed it out! 2-0 Count, and the coach from the dugout with the book starts screaming TIME! He calls me over and says they batted out of order. I looked at the book, and brought the correct batter to the plate. I'm thinking, wow, smart coach because he knows it can't be an OUT until after the AB.
Then he says "so that's an out right?"
