Lost Ball
In short
A ball is lost if you do not find it within three minutes of you or your caddie starting to search. Under Rule 18.2 you then take one penalty stroke and play again from where you made your last stroke. A provisional ball can often save you the walk back.
What does lost ball mean in golf?
Every golfer loses a ball now and then. The shot flies into long grass, a wood or dense undergrowth, and despite searching it never turns up. The Rules of Golf set out exactly when a ball counts as lost and what to do then. The aim is that play should not be held up for ever and that there are clear rules for everyone.
You will find the rule in Rule 18.2. It sits together with out of bounds, because the consequence in both cases is the same: one penalty stroke and stroke and distance. The only difference is whether the ball has disappeared on the course or lies beyond it. Whether a ball is lost is therefore not a matter of feeling but of time.
The three-minute rule
A ball is lost if it is not found within three minutes of you or your caddie starting to search. Until 2018 it was five minutes. The shorter time is meant to improve pace of play.
The clock runs from the moment you start searching, not from the stroke. If you find a ball within the time, you then have a reasonable time to check that it is your own. After that you play it on.
Once the time is up, the ball is lost even if it turns up moments later. If you play a ball found later anyway, it counts as a wrong ball and two penalty strokes follow. The same applies if you have already put another ball in play.
What to do when the ball is lost
Under Rule 18.2 you have only one option: stroke and distance. You add one penalty stroke and play again from where you hit the lost ball.
Depending on the situation, that means:
- If it was a tee shot, you play again from the teeing area. Your next stroke is the third.
- If it was a stroke from the general area, you drop a ball in an area of one club-length around the old spot, not nearer the hole.
- If it was a stroke from the putting green, you replace the ball on the old spot.
There are exceptions. If it is virtually certain that an outside influence moved the ball, that it lies in a penalty area, or that it lies on or in a movable obstruction or an abnormal course condition, other procedures apply. Under the Rules, virtually certain means a likelihood of at least 95 per cent.
The provisional ball: saving the walk back
If you suspect your ball may be lost, you may play a provisional ball under Rule 18.3 before you walk forward. You must expressly say that it is a provisional ball. A phrase such as ‘I will play another one’ is not enough.
If the first ball is found within three minutes and lies on the course, you give up the provisional ball and play the first one. If the first ball is lost, the provisional becomes the ball in play. You still add the penalty stroke, but you save time and walking. The ball is only allowed, though, if the first ball might be lost outside a penalty area or be out of bounds. If it can only be in the penalty area, a provisional ball is not allowed.
A practical example: par 4 with long grass
You are playing a par-4 hole. Your tee shot lies well on the fairway, which is stroke 1. Your second shot from about 130 metres pulls left and disappears in long grass. You know it must be there somewhere but cannot find it. You search for three minutes. Then the ball is lost.
You go back to the spot of your second shot. There you drop a new ball in an area of one club-length, not nearer the hole. The count runs:
- Stroke 1: tee shot
- Stroke 2: lost ball
- Stroke 3: penalty stroke
- Stroke 4: new ball from the drop onto the green
Two putts later you write down six strokes, which is a double bogey. Had you played a provisional ball beforehand, you would have been spared the walk back. The score would be the same, but the group behind you would have lost less time.
Common mistakes and tips
These mistakes are common with a lost ball:
- Searching for longer than three minutes. After that the ball is lost even if you keep looking.
- Playing a ball found later although a replacement ball is already in play or the time had expired. That is a wrong ball.
- Not clearly announcing the provisional ball. Then the second ball is the ball in play.
- Moving the ball while searching and fearing penalty strokes. If you only move it accidentally, there is no penalty. Put it back on the spot.
- Searching too long and holding up the group behind. Let faster groups play through.
Tip: watch the ball and remember a landmark, such as a distinctive tree. Ask your playing partners to help look. Several pairs of eyes find it faster than one. And use the provisional ball whenever you have doubts.
How it differs from out of bounds and unplayable
Three terms are often mixed up. A lost ball has disappeared on the course and cannot be found. A ball out of bounds lies beyond the boundary of the course. Rule 18.2 covers both cases with stroke and distance. An unplayable ball has been found but should not be played. Rule 19 applies to that, and you have three options for one penalty stroke.
There is also a boundary with the penalty area. If it is virtually certain that the ball lies in the water, you take relief under Rule 17 for one penalty stroke. That is usually more favourable than stroke and distance. Some courses also offer a Local Rule under which you may drop a ball without the walk back for two penalty strokes. Whether that applies is stated on the scorecard.

Frequently asked questions
How long may I search for a golf ball?
Three minutes, from the moment you or your caddie start searching. After that the ball is lost, even if it turns up shortly afterwards. Until 2018 it was five minutes. The time you need to check whether a found ball is yours is added on top.
How many penalty strokes is a lost ball?
One penalty stroke under Rule 18.2, combined with the loss of distance. You play again from where you made your last stroke. If the course has adopted an alternative to stroke and distance, you may instead drop a ball for two penalty strokes.
Do I have to announce a provisional ball?
Yes, expressly and before the stroke. Say clearly that you are playing a provisional ball. Without an announcement the second ball is the ball in play and the first is given up. A provisional ball is only allowed if the first could be lost outside a penalty area or be out of bounds.
What happens if I find my ball after three minutes?
It stays lost. If you play it anyway, it is a wrong ball and two penalty strokes follow in stroke play. You must carry on with stroke and distance instead or, if you played a provisional ball, play that one.
What is the difference between a lost ball and a ball out of bounds?
A lost ball cannot be found on the course. A ball out of bounds lies entirely outside the boundary of the course. Rule 18.2 covers both cases, and both lead to one penalty stroke with stroke and distance. The difference lies only in the cause.
