Had a game 9/25 where center did the spin of the ball tips180 turn around. Warned him, flagged him 2 times the rest of the game. He walked up to me later, and said the previous 4 games he had done it on occasion and no one penalized him. I said it's the rule, and I gave you a warning. Umpires, we need to do our jobs. Just confuses the kids when they get penalized for something they've done but had'nt got penalized.
