Step #1: Take your ball mark repair tool and insert the prongs into the turf at the edge of the depression. Note: Do NOT insert the prongs into the depression itself, but at the rim of the depression.
Step #2: The next step is to push the edge of the ball mark toward the center, using your ball mark repair tool in a “gentle twisting motion,”.
Step #3: Once you’ve worked around the rim of the ball mark with your repair tool, pushing the grass toward the center, there’s only one thing left to do: Gently tamp down the repaired ball mark with your putter smooth the putting surface.
