Abstract: A golf ball mark repair tool is mounted on a hand grip end of the shaft of a golf club. The repair tool has a mounting base secured to the hand grip end of the shaft, and an elongated prong attached to one end of the base and projecting therefrom. The prong has a configuration for prying turf to repair a ball mark. The shaft of the golf club provides a handle extension for the base of sufficient length for permitting a player to operate the tool to repair the ball mark by gripping the handle extension while standing erect. The repair tool also includes a protective cover removably mounted to the club shaft end and having a hollow interior for extending over and enclosing the turf prying prong. Preferably, the cover constitutes an extension of the club hand grip.
