Unplayable Ball
In short
An unplayable ball is a ball you can no longer or do not want to hit. Only you decide whether it is unplayable, anywhere on the course except in a penalty area. Under Rule 19 you then take relief for one penalty stroke, either by stroke and distance, back on the line or laterally within two club-lengths.
What does ‘unplayable ball’ mean in golf?
Sometimes a ball ends up where a stroke is impossible or unreasonable. It lies deep in a thorn bush, behind a tree trunk or in a root that blocks your stance. In such a case you may declare the ball unplayable. The rule for this is Rule 19 of the Rules of Golf.
Importantly, the decision is yours alone. Neither playing partners nor the Committee can tell you that the ball is or is not unplayable. You may declare a ball unplayable even if it lies on the fairway. Whether that is wise is another matter. The rule applies everywhere on the course with one exception: you may not declare a ball unplayable in a penalty area. Rule 17 applies there.
The three options at a glance
If you declare the ball unplayable in the general area or on the putting green, you take a penalty stroke and have three choices:
- Stroke and distance: you play again from where you made your previous stroke. That is always possible, even if you cannot find the ball.
- Back on the line: you draw an imaginary line from the flagstick through the spot where the ball lies and drop on that line behind the ball, as far back as you like.
- Lateral: you drop within two club-lengths of the ball's spot, not nearer the hole.
For the second and third options you must know where the ball lies. The ball's spot is the reference point. If the ball is in a tree, it is the spot on the ground directly below. A club-length is your longest club other than the putter.
Step by step
With a clear procedure it goes quickly:
- Decide that the ball is unplayable and tell your playing partners.
- Choose one of the three options.
- If needed, mark the reference point, for example with a tee.
- For back on the line you drop the ball on the line. Since 2023 it must come to rest within one club-length of where it first touched the ground. It must not come to rest nearer the hole than the reference point.
- For lateral relief you measure two club-lengths and drop within that area.
- Drop from knee height and let the ball fall without throwing or spinning it.
- Record the penalty stroke.
If the ball rolls out of the relief area after dropping, drop again. After two failed attempts you place the ball where the second drop first touched the ground.
The special case of bunkers
In a bunker Rule 19.3 applies with special features. You have the same three options for one penalty stroke. For back on the line and lateral relief, however, the ball must stay in the bunker. So you cannot simply drop out of the sand.
There is a fourth option, though: you take back-on-the-line relief outside the bunker. For that you take two penalty strokes instead of one. This option is useful when the ball is buried against the bunker face and no sensible stroke is possible. You pay one extra stroke but get out of the sand. Think beforehand whether two penalty strokes are really better than a calm escape shot.
A practical example: par 4 with a bush
You are playing a par-4 hole. Your tee shot is good, which is stroke 1. Your second shot flies right of the green and ends up in a dense bush, which is stroke 2. You find the ball, but a stroke is impossible because branches block the swing. You declare it unplayable.
You now have three options:
- Back to the spot of your last stroke: the stroke from there would be your fourth, and you lose a lot of distance.
- Back on the line: you drop behind the bush on the line from the flagstick through the ball.
- Lateral: you drop within two club-lengths beside the bush.
You choose lateral relief. With the penalty stroke, the shot from the drop is your fourth. It takes you onto the green. One putt later you write down five strokes, which is a bogey. An attempt from inside the bush could easily have taken even longer.
Common mistakes and tips
These mistakes are common with an unplayable ball:
- Dropping nearer the hole. With every option the ball must not come to rest nearer the hole than the reference point.
- Forgetting the penalty stroke. Every form of relief costs one stroke, or two in a bunker if you choose that option.
- Measuring with the putter. The longest club other than the putter counts.
- Declaring unplayable in a penalty area. Rule 17 applies there with its own options.
- Getting the reference point wrong, especially for balls in trees.
- Insisting on stroke and distance when lateral relief would be much easier.
Tip: check the lie, your stance and the swing path briefly, then decide quickly. If a clean stroke is not possible, the one penalty stroke usually costs less than several failed attempts, and your group does not have to wait.
How it differs from a lost ball and free relief
An unplayable ball is not the same as a lost ball. The lost ball cannot be found. Only stroke and distance remains. The unplayable ball has been found but cannot or should not be played.
Free relief is also something else. For unusual course conditions such as ground under repair or an animal hole you get free relief under Rule 16. That does not cover bad lies that are part of the game. An unplayable ball always carries a penalty stroke. In return it has one big advantage: you decide for yourself and can free yourself from almost any lie.
Try it at Golf Lounge
At Golf Lounge Resort Hamburg you learn how to handle an unplayable ball on the DGV Platzreife course. The theory part covers rules, etiquette and safety on the course and is linked with practice, guided by PGA coaches. Groups are small, with no more than six people, and the course usually comprises four to five sessions of two hours. The exam takes place every Saturday on site in Moorfleet.
Frequently asked questions
Who decides whether a ball is unplayable?
Only you. Rule 19 gives no playing partner and no Committee a say. You may declare a ball unplayable anywhere on the course except in a penalty area. The options there come from Rule 17. That is true however the lie looks from the outside.
How many penalty strokes is an unplayable ball?
Normally one penalty stroke, whichever of the three options you choose. In a bunker you may stay in the bunker for one penalty stroke or drop back on the line outside the bunker for two penalty strokes. There are no more penalty strokes.
May I declare a ball unplayable in a penalty area?
No. In a penalty area you may not declare a ball unplayable. You take relief under Rule 17 there, with options depending on yellow or red markings. A ball in water is therefore not a case for Rule 19. If the ball lies just outside the penalty area, however, you may declare it unplayable.
Do I have to find the ball to declare it unplayable?
For stroke and distance, no, because you play from the old spot. For back on the line and lateral relief you must know where the ball lies. If the ball cannot be found, only stroke and distance remains. If you know the spot, you will usually choose the lateral option.
How do I measure two club-lengths correctly?
Take your longest club other than the putter, usually the driver. Measure two club-lengths from the ball's spot in any direction, but not nearer the hole. You drop the ball from knee height within that area. The ball's spot is the starting point of the measurement.
