If you're the thrower, you'll be needing some tips to make sure that ball goes to the right place.
Stand with your legs slightly apart, with your weight on the opposite foot to your throwing arm. Get a good solid grip on the ball, and bring your arms behind your head, bending them fully at the elbow.
Shift your weight forwards, and guide your arms forwards in a nice, smooth motion.
When the time is right, release the ball.
A good tip is to ‘spin' the ball as it's thrown, to give it a good strong targeted direction.
All being well, the ball should sail directly between the two lines of teams, towards the intended player.
