I'm a golfer - not an athlete.

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

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.

He can switch from a kid apparently playing for the heck of it, to someone with the predatory instincts of an alligator. The kid is all smiles, but watch out for his teeth.

The story of the week is you have got to putt well to win the Masters and I haven't putted well.

Now I'm giving up a little in the week-to-week tournaments but reaping the benefits in the majors.
