Major question 'getting on nerves' of Westwood after return to top

World No 1 Lee Westwood is growing increasingly weary with being asked about his failure to win a first major title and said in Seoul yesterday the question was getting on his nerves.

The Briton, speaking in Seoul ahead of the Ballantines Championship, said becoming world No 1 and winning a major were separate issues and that his only focus was to keep playing good golf.

"The amount of times I have to answer it gets on my nerves," Westwood said. "This might be the very last time I could be answering this question. It could be no comment after this.

"The world rankings and major championships are two completely separate things," added Westwood, who celebrated his 38th birthday by winning the Indonesian Masters in Jakarta at the weekend.

That victory, combined with fellow Englishman Luke Donald's failure to win The Heritage, moved him back above Germany's Martin Kaymer into top spot.

"I haven't won a major yet but hope to do so soon," he added. "I've had a lot of good chances to win majors but it just hasn't happened. But the world rankings are all about consistency and playing well week-in and week-out, which I tend to do. The secret to being world number one is having the consistency, and all parts of your game have to be good to do that."

Westwood, who was world No 1 for 17 weeks after deposing Tiger Woods in November, acknowledged the pressure was greater having reached the summit of men's golf.

"Obviously with being number one there is a lot more responsibility," he said. "You have a lot more things to do. People want a lot more of your time, it becomes a bit difficult to cram everything in and leave time for practising golf and doing what got to you where you are. That's the toughest part of it."

Three-times major champion Ernie Els and local favourite Yang Yong-eun are set to push Westwood this week at the Ballantines. Teenage Korean sensation Noh Seung-yul, the reigning Asian Tour Order of Merit champion, and European Ryder Cup players Ian Poulter and Miguel Angel Jimenez are also among a quality field at the Blackstone Golf Club near Seoul.

"My confidence is high," said Westwood. "I didn't realise the world number one had never competed in Korea before so it's a bit of an honour."
