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

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.

It's such a psychological and mental game, golf, that the smallest wrong thing at the wrong time can distract you from what you're trying to achieve.

It wasn't easy to putt this week, ... The short ones were really tough.

There were some good things about playing the week before the Masters - and there were some drawbacks.

I spent hours as a kid on the putting green of the local golf course imagining I was sinking a putt to win the Masters.
