Do I have to announce a provisional ball?

Yes, you must announce it. Before you hit a provisional ball, you have to tell someone you're playing a provisional under Rule 18.3 — just saying 'I'm hitting another' isn't enough. If you don't announce and play from the same spot, that ball is now your ball in play with a stroke-and-distance penalty.

What counts as a proper announcement

You have to use the word "provisional" or otherwise make it unmistakably clear that you're playing under Rule 18.3. Saying "I'm playing a provisional" or "I'm playing a ball under Rule 18.3" works. So does "I'm going to play another just in case." The key is that anyone listening understands this is a provisional ball, not a replacement ball in play.

What happens if you don't announce

If you play a ball from where your last stroke was made without announcing it as provisional, that ball automatically becomes your ball in play under penalty of stroke and distance. Your original ball is lost — even if you find it five seconds later. You've effectively put a new ball in play with the penalty attached.

When no one is around to hear you

If there's genuinely nobody nearby who could hear your announcement, you're allowed to play the provisional ball first and then tell someone what you did as soon as practicable. This covers situations like playing alone or when your group is far ahead. You still have to inform someone when it becomes possible.

Exceptions that change the answer

• No one is within earshot when you play the provisional ball → You may play the provisional ball first, then inform someone of your actions as soon as possible.

Frequently asked questions

Is saying "I'm hitting another one" enough to make it a provisional ball?

No. "I'm hitting another one" or "I'm playing again" does not clearly indicate a provisional ball. You must use the word "provisional" or reference Rule 18.3 so there's no doubt about your intent.

Can I announce the provisional ball to my caddie or does it have to be another player?

Yes, announcing to your caddie counts. The rule says "to someone" — your caddie, a fellow competitor, or anyone within earshot satisfies the requirement.

What if I announce it but my playing partners didn't hear me?

The announcement must be made to someone who can actually hear it. If nobody heard you, the announcement didn't happen. If no one was nearby at all, you can play first and inform someone afterward.

If I forget to announce and hit a provisional, then find my original ball, can I play the original?

No. Once you play a ball from the previous spot without announcing it as provisional, that ball is your ball in play under stroke and distance. The original ball is lost and cannot be played, even if found immediately.

Does "I'm going to play another just in case" count as a valid announcement?

Yes. The official interpretation lists "I'm going to play another just in case" as an example of a statement that clearly indicates a provisional ball is being played.
