Whats the ruling...

...on broken balls?

I played Silverwood in Armagh last Sunday and on the 17th on my second shot into the green my ball split in two and... well... that's it.

It was a social game so no-one was overly concerned if I stayed wholey within the rules, I just dropped a ball where I was standing and played the shot again.

But for future reference: what would the ruling be?

In simple terms, if your ball is bust, you can swap it for a new one
