Lee Westwood tired of justifying his number one status

Lee Westwood is growing tired of justifying his position as world number one, after having his credentials questioned for not winning a major.

The 38-year-old Englishman returned to the top of the rankings this week after winning the Indonesian Open.

However, critics, including Sir Nick Faldo, a six-time major winner and former world number one, have suggested the current ranking system is flawed.

"The world rankings and majors are separate things," said Westwood.

"The only thing that gets to me about answering that question is the amount of times I have to answer it; it gets on my nerves.

"This might be the very last time I answer this question; it could become 'no comment' after this.

"I've had a lot of chances to win majors recently and it just hasn't happened. The world rankings are about consistency and playing well week-in, week-out, which I tend to do."

Westwood, who is in South Korea for the Ballantine's Championship at Blackstone Golf Club near Seoul, first took over as world number one from Tiger Woods, who had held the position for a record five years, at the end of October 2010.

The Worksop-born golfer was ranked the best in the world for 17 weeks until he was dethroned by Germany's Martin Kaymer in late February.

But victory at the Indonesian Open, coupled with world number three, Luke Donald's, failure to win the Heritage Tournament in America over the weekend, moved Westwood back to number one, with Kaymer dropping to two.

Donald, another Englishman who is yet to win a major, would have taken over at the top had he beaten Brandt Snedeker in a play-off in the South Carolina tournament.

However, prior to Donald's final round at Hilton Head, Faldo tweeted: "Nothing at all against Luke Donald and Lee Westwood as No. 1 - that's the system - but I think system should give extra points for a major win."

Meanwhile, respected Florida Times-Union golf writer, Garry Smitsexternal-link, wrote: "I think there's something wrong with that system."

And the Charlotte Observer commentedexternal-link: "What's interesting is how the No. 1 spot is now getting traded like bad stock but don't ask me to explain how the rankings work other than to say they're based on a rolling two-year period."

Westwood, who heads a world top 10 that features six Europeans including five from Britain and Northern Ireland, countered: "It was nice to get back to number one but to be honest I hadn't played the first part of the year like the world number one and the world rankings are reflective of how you played."

Northern Ireland's US Open winner, Graeme McDowell, and his countryman Rory McIlroy are fifth and seventh, while England's Paul Casey is eighth.

Four-time major winner Phil Mickelson is the highest ranked American at fourth with Woods (14 majors), Steve Stricker and Matt Kuchar at sixth, ninth and 10th respectively.
