By the time Ryo Hisatsune reached the eighth hole in the final round of the Crown Australian Open, he would have known that his chances of claiming the title had evaporated.

The Japanese star began the day at six-under and already facing an eight-shot deficit on leader Rasmus Neergaard-Petersen.

Rory McIlroy was forced to play a shot with his ball wrapped around a banana peel the day after he produced an air shot.

A compatriot of Hisatsune, Hideki Matsuyama, was also involved in a rules incident this week at the Hero World Challenge. There, his golf ball was run over by a cart, although on that occasion, he avoided a penalty as his ball had been moved by an outside influence.
