Believe it or not, coach's will try to play with you and mess with your mind. If they think their antics can influence a future call in their favor they will do it.

You can't let a coach or player chirp at you constantly during the game about your strike zone. An occasional reaction is normal, but a constant barrage of verbal criticism must be stopped. And never mention your "zone" before a game, if they ask just say, "what does the rule book say, coach?".

As for the time between innings, you control that, not the players. If you are ready to go, then go. Don't wait. If the pitcher is just standing there, waiting for his catcher, then go to the bench and hustle up the catcher. The pitcher is NOT entitled to a single warm-up pitch if a minute has elapsed.
If you are waiting for a batter, just call play and call the pitches. The problem with the leagues lackadaisical attitude is the umpires fault. Teams will take every minute you give them, and want more.
