The GK tries to catch the ball at the highest point possible. The server tries to lob balls over the GK into the goal. The GK back-peddles and tries to make the save. The GK catches the high ball by jumping up off of one leg and propelling the other leg up. The knee on this leg comes up in front of the body and also serves to protect the GK from contact with other players.
