Okay, if you insist on demanding specifics, tell me where in the question it says the umpire didn't permit the request. Show me that the manager didn't talk to his players in the field?
Obviously, these are rhetorical questions as you cannot prove the negative. If you read every occurance on the field and attempt to analyze it they way you do these questions, you will end up second-guessing yourself and that will not help make you a better umpire.
I know of umpires who have worked Nationals and did a fine job, but not get a game on the final day for one reason - according to the UIC(s), they went looking for trouble.
You know, like when the rule book says the pitcher (SP) shall hold the ball in front of the body and the body must be facing the batter. Does that mean you do not let them pitch if the body is slightly angled and the ball is just behind the plane of the player's hips. No, it means that everything is legal as long as the pitcher is not facing away from the batter and the ball is not behind the pitcher's body, or leg. I threw that in there because I anticipate the argument that the leg isn't part of the body.
