Can I be disqualified after stroke play ends for returning a lower score?

Yes, you can be disqualified after the competition closes if you returned a score for any hole lower than you actually took. The exception: if the lower score was only because you didn't know about a penalty you incurred, you get two penalty strokes instead of DQ.

What the rule says

In stroke play, once you hand in your scorecard, the scores on it are final. If any hole shows a number lower than what you really shot, the Rules say you're disqualified. This applies even after the competition has officially closed and the results are posted. The Committee can and will DQ you if they discover the error later, whether it's hours or days after.

The one exception that saves you

If the only reason your scorecard shows a lower number is that you failed to include a penalty you genuinely didn't know about when you signed, you're not disqualified. Instead, the Committee adds the general penalty — two strokes — to the hole where the breach happened. Your adjusted score stands, and you stay in the competition. This only works if you truly had no knowledge of the penalty before returning the card.

What counts as "didn't know"

You didn't know if no one told you, you didn't see the breach yourself, and a reasonable player in your position wouldn't have realized it either. If you had any inkling — a playing partner mentioned something, you felt the club touch sand, you saw the ball move — you're expected to include the penalty. Claiming ignorance after the fact doesn't work if the facts say you should have known.

Exceptions that change the answer

• The lower score on the card is solely because you omitted a penalty you had no knowledge of before signing → You are not disqualified; the Committee adds two penalty strokes to the hole where the breach occurred and your corrected score stands

Frequently asked questions

Can I be DQ'd days after the tournament ends?

Yes. If the Committee discovers you returned a lower score than you actually took, they can disqualify you even after the competition has closed and prizes have been awarded.

What if I made an honest math error adding up my score?

That's still a lower score returned for a hole (or the total), so the DQ penalty applies. The exception only covers unknown penalties, not addition mistakes.

My playing partner told me about a penalty after I signed. Am I safe?

No. Once you've been made aware of a penalty before returning the card, you must include it. The exception only applies if you had zero knowledge at the moment you handed in the scorecard.

Does this apply to match play too?

No. This rule is specific to stroke play. In match play, a wrong score on a hole usually just means loss of that hole, not disqualification.

What if the Committee made a mistake posting the scores?

That's an administrative mistake under Rule 20.2d(2), not a player error. There's no time limit for the Committee to fix their own posting errors — your result gets corrected without penalty to you.
