Golf ball is on fringe. There is a sprinkler head directly in front of the ball (within 2 club lengths) which doesn’t allow a putt
the sprinkler head is within 2 club lengths of the green
Sprinkler head does not affect stance or swing but it doesn’t allow a putt since the ball would roll over the sprinkler head
the sprinkler head is below the grass and not protruding abound ground
does player get relief
