PLEASE be Considerate, Repair Ball Marks on the Greens
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. Push the edge of the ball mark toward the center, using your ball mark repair tool in a gentle twisting motion.
This is the step where golfers who incorrectly “repair” ball marks usually mess up. Many golfers believe the way to “fix” a ball mark is to insert the tool at an angle, so the prongs are beneath the center of the crater, and then to use the tool as a lever to push the bottom of the ball mark back up even with the surface.
Do not do this! Pushing the bottom of the depression upward only tears the roots, and kills the grass.
Wrong: Using the prongs as levers to push up the bottom of the depression.
Right: Using the prongs to push grass at the edge of the depression toward the center.
Just use your ball mark repair tool to work around the rim of the crater, so to speak, pushing the grass at the edge toward the center of the depression. One way to envision this is to picture reaching down with your thumb and forefinger on opposite sides of the ball mark and “pinching” those sides together.
Step 3. Once you’ve worked around the rim of the ball mark with your repair tool, pushing the grass toward the center, gently tamp down the repaired ball mark with your putter or foot to smooth the putting surface.
