I'm not that big on golf myself, but from what I understand, dropping the ball in the wrong position brought a 2 stroke penalty which he didn't acknowledge at the time. He signed and submitted his scorecard incorrectly as a result and admitted he'd dropped it a few feet further back to improve his shot.

Submitting an incorrect scorecard means automatic disqualification, unless he can't have know he's broken a rule. So what they're saying is, he didn't know he dropped it in the wrong position - which can't be true because he said as much in his interview - or that he can't have known that doing so should bring a 2 stroke penalty.

I'm not sure why nobody pointed it out or noticed at the time, I guess they won't have know he hadn't marked his card properly until afterwards. Still, for someone who's been pro as long as he has, he should know the rules.

That said I'm not too bothered about him getting a penalty rather than DQ'd. I like watching him play and he's been playing very well the last few days. I just think most other people would have been told "Sorry, you submitted a wrong score, you're out." I'd quite like him to go and win now, just to see the reaction from people who aren't happy at him just getting the penalty.
