Abstract: A golf ball retriever is attached to the handle of a golf putter and is used to retrieve a golf ball from a playing surface and to concurrently deposit a golf ball marker in place of the golf ball. The apparatus includes a fork rotatably mounted to a support body that is secured to the extremity of the handle of a golf club shaft. The fork has a pair of arms which lie substantially in a common plane and are arcuately curved toward each other. One of the arms is longer than the other. A golf ball marker with a turf-engaging spike is placed on the underside of the body supporting the fork and is held thereto by a magnet within the support body. The fork is moved toward the golf ball while residing at a lifting angle inclined about fifteen degrees downwardly relative to the golf club shaft. The arms of the fork engage the undersurface of the golf ball and cradle it therebetween.
