Repairing ball marks is something we should always be doing.
Unfortunately, maintenance staffs often spend a significant amount of time each year fixing unrepaired ball marks so they don’t negatively impact playability and aesthetics for weeks to come.
The last thing maintenance teams need to be doing is a job we can easily do ourselves. If you repair your ball mark and a couple of others with the proper technique, you’ll be doing everyone a favour.
