"It's a mindset that's changing at the moment. When you've been in that situation before and you know you can do it again.
"I was thinking about not being here this week. Hitting it so badly. My coach flew in and my wife said to me, 'listen, maybe this is your week'. And look what happened, it's my week.
"I don’t know if there are any emotions at the moment. I was thinking after Ras Al Khaimah to go home and practice because the swing’s not there. I spoke to my coach, who flew my assistant coach in, we worked hard to get the swing back to where it was. I’m still speechless how it happened this week.
"The chip on 18 was phenomenal. It was one that is either perfect and coming back or it’s in the pond. I played it exactly how I wanted to. Just glad it came out to about half a foot and I knocked it in."
Finland's Sami Välimäki carded a 66 for solo second place at 18-under.
