The question is when should you get relief from a divot in the fairway? It’s not black and white. Up until you see any grass growing in the divot? What stinks is that a player rakes a sand trap, which is a hazard, so the next person in it gets a good lie, but you can get terrible lies in the fairway. The rub of the green they say. I don’t think there’s really a question, you should always get relief from a fairway divot. It makes no sense why you shouldn’t. Just get the standard club length that doesn’t put you closer to the hole/improve the lie (going from rough to fairway). Treat a divot like a sprinkler head if the ball is in it. But what constitutes a divot? When does an old divot become regular fairway?
