A slightly complicated incident

[Foxholer]

No, but the rules are generally precisely written and don't usually say more than necessary. This bit just seems rather more "helpful" than normal - and I was wondering if there was any specific reason why that might be?

I agree. They probably had lots of queries about what a 'wrong ball' was, so decided the simplest thing to do was clarify it in The Rules.

As an aside to the OP, but leading from a couple of responses, the definition a wrong ball is

"A “wrong ball’’ is any ball other than the player’s:

ball in play;
provisional ball; or
second ball played under Rule 3-3 or Rule 20-7c in stroke play;

and includes:

another player’s ball;
an abandoned ball; and
the player’s original ball when it is no longer in play.

I'd have thought that the bits highlighted red were fully covered by the foregoing section of the definition. So I wonder why it's thought necessary to include them? Anyone got knowledge or suggestions as to reasons why they are there?

People do not trust their ability to read terse writing.
