The goal keeper must be able to reach out of the water and catch the high balls sent into the goal. She must also be quick. Remember, you can use both hands to handle the ball. The guards always must help the goal keeper cover the goal area, never leaving her unguarded, yet they must not interfere with her or prevent her seeing clearly. WATER POLO RULES.
