Abstract: A device for teeing a golf ball includes a ball support member that has at least two opposed feet and that defines at least one ball locating formation for supporting a golf ball interposed between the feet. The, or each, ball locating formation is in a plane that is spaced from a plane in which the feet are positioned. The ball support member is of a resiliently flexible material to permit the, or each, ball locating formation to deflect, against a bias of the ball support member, towards the plane of the feet when either or both of the ball support member and the ball are struck with a golf club head.
