A goalie, also known as a goalkeeper, is a player in sports like hockey and soccer whose primary role is to prevent the opposing team from scoring. Positioned near the goal, the goalie uses their body, hands, and equipment to block shots and keep the ball or puck out of the net. Goalies often wear specialized gear, such as padded gloves and helmets, to protect themselves from fast-moving objects. They must have quick reflexes, good hand-eye coordination, and the ability to read the game to anticipate opponents' actions effectively.
