My dad said: 'It looks like you'll be world No.1 in a few hours and I wanted to be the first to say congratulations.

In my case what happened next in 1999 was that I fell apart over that back nine. When I saw I was in genuine contention that year I felt like throwing up. That remains probably the most nervous I've ever been on a golf course.

I know I'm good enough to contend in each and every major I play.

People always say golfers don't smile. But there is so much psychology in golf so we have to be a bit robotic.

The Singapore Open is the flagship event of the Asian Tour, it is a massive event and it is being played in a great place. I love coming here and it is good to be back.

The satisfaction you get when you finally beat your dad is amazing, that rush of adrenaline.

You're the only one in control over your golf ball. It's not like tennis: you're hitting a shot and somebody's hitting it back at you.
