The other side is when a Coach talks a weak umpire into a call.
My son's HS was playing another team in the last game of the regular season. The winning team would clinch a spot in the state playoff's, the loser would only make it depending on what happenned in other games.
He came in to relieve in the bottom of the 6th. The game was tight. Runner's were on first and second. From the first pitch the opponent's Coach started yelling "Balk" over and over again. He was Coaching third.
After my son got one out, he was holding the runner at second. The "Balk" yelling continued. He looked at the runner at second, looked home, looked back at the runner and the field umpire calls a balk. Nothing had moved accept his head and neck to check the runner.
As it turned out, it didn't matter. They didn't score and we won the game. Both teams made the playoffs.
My son has seen this Coach several times since. Every time, the Coach yells "Balk" and starts laughing. He knows he got away with one. My son should be ready when we see them again this year.
