my u14 son has the habit of calling my ball while charging up when his team restarts the game. He has found this often leads to the catchers becoming confused and leaving the ball to bounce or to be taken by him or his team mates to his teams advantage. He has been told by a coach that calling "my Ball" is not allowed and he could be penalized by a switched on ref. i am trying to find out if this is the case or not. can anyone help?
