To avoid sloppy play, the defenders must throw the ball with two hands. If the attacking team's ball goes out of the grid, the coach will immediately put another ball into play. But if the defending team's ball goes out of the grid, it is up to them to chase the ball down and get back into the field of play. This discourages 'wild' throwing. They hit the attacking team's ball with either one of their own balls that has been thrown with two hands at the attacking team's ball.
Variations Play with one or three balls for the defending team.
Play with two balls for the attacking team. Only allow the defending team to 'bowl' their ball at the attacker's ball. Allow one handed 'baseball' throwing. Attacking team coaching points Make sure attacking players give good supporting angles both near the ball, and, far away from it. Movement without the ball.
