Under a bush. Wedged in a root. Six inches from a tree trunk on the wrong side. Every round has one, and the Rules are more generous here than most golfers realise. Rule 19 is one of the few places where the book is actively trying to help you.
You are the only judge
Nobody else gets a vote. You may declare your ball unplayable anywhere on the course — fairway, rough, bunker, up a tree — with one exception: not in a penalty area. Inside a penalty area, Rule 17 is the only game in town.
You do not have to prove the ball is genuinely unplayable. You do not have to try to hit it first. If you want to take the penalty, you take the penalty.
The three options, all for one stroke
Stroke and distance
Go back and play again from where you played your last shot. Always available, always the safest, almost never the one you want — but it is the only one of the three that works no matter how bad the situation is.
Back-on-the-line relief
Keep the spot where your ball lies between you and the hole, and go straight back along that line as far as you like. Pick a point on that line, and you may drop within one club-length of it — but no nearer the hole than that point. The line is fixed; how far back you go is entirely up to you.
Lateral relief
Two club-lengths from where the ball lies, no nearer the hole. The fast one, and the one that gets used ninety percent of the time.
A club-length means the longest club in your bag other than the putter — for nearly everyone, the driver. Not the wedge in your hand. Measure with the driver and you routinely gain a foot or more of relief area over people who measure with whatever they are holding.
Back-on-the-line is underrated
Most golfers reach straight for the two club-lengths because it is quick. But look at the geometry before you do. Two club-lengths sideways in thick trees often leaves you in thick trees. Going back on the line is unlimited — you can walk back thirty yards to a clean lie in the fairway with a full swing and an open shot.
The catch is that back-on-the-line is a line, not an area. It runs from the hole, through the point where your ball lies, and straight back. Step off that line and your drop is in the wrong place. Pick your spot on the line first, mark it, then drop within a club-length of it.
The bunker, and the escape hatch
Ball plugged under the lip with no shot? Here is where Rule 19 earns its keep.
All three normal options are available in a bunker for one penalty stroke — but if you use back-on-the-line or lateral relief, you must drop inside the bunker. Which frequently means dropping into another bad spot.
So there is a fourth option, and it exists only for bunkers:
For two penalty strokes, you may take back-on-the-line relief outside the bunker.
Same line — from the hole through where your ball lies — but now you can go back as far as you want and get completely out of the sand.
Two strokes sounds steep. Compare it to the alternative. A ball buried under the front lip that you cannot advance is a three-shot bunker on a bad day and a card-wrecker on a worse one. Taking two and playing your next from clean grass, with a full swing, at a distance you actually like, is frequently the lower-scoring play. Tour players use it. So should you.
What you cannot do
- Not in a penalty area. Worth saying twice. If your ball is inside the red or yellow stakes, Rule 19 does not apply at all — you have not lost your options, they are just Rule 17's options instead.
- Not for a ball you cannot find. Unplayable requires a ball you know the location of. If it is lost, that is Rule 18.2 and stroke and distance, no matter how confident you are about where it went.
- Not to improve where you drop. Standard relief procedure applies — knee height, inside the relief area, and if it rolls out you drop again, then place.
Up a tree
Yes, this is covered, and it is a fun one. If you can identify your ball in the tree, it is not lost — so you can declare it unplayable and take relief measured from directly below where the ball rests. If you cannot identify it as yours, it is lost, and you are back to stroke and distance.
Which is a decent argument for putting a mark on your ball. A Sharpie dot is the cheapest ruling in golf.
