A body having an annular surface and pins movable in a radial direction with respect to the annular surface. The annular surface may have simulated turf. When the pins are retracted, the body can be inserted in the hole with the annular surface in flush alignment with the surface of the turf surrounding the hole. The pins can then be extended into the material, such as soil, that surrounds the hole. The device can thus be inserted to the precise depth necessary to level the annular surface with the surrounding turf. The pins can quickly and easily be extended to secure the device in the hole or retracted to remove the device from the hole. A golfer can retrieve the ball by inserting fingers or a ball-retriever into the central opening of the annular surface without inadvertently dislodging the device because the pins securely hold the device in place.
