Three-time major champion Vijay Singh had no intention of slowing down his pursuit of more titles after winning the Chevron World Challenge at Sherwood Country Club on Sunday.

The 45-year-old Fijian has piled up 34 victories on the PGA Tour, three of them in 2008, and plans to compete at the highest level for another five years.

"I think there's no limit to what age you should quit," the workaholic Singh told reporters after triumphing by one shot in the elite 16-man event hosted by Tiger Woods.

"I'm a great example. Look at (Americans) Kenny Perry and Fred Funk, who won TPC (Players Championship) when he was 48.

"Winning this many tournaments doesn't mean it's a miracle; I think there will be guys out there that are going to do the same thing. It's just how many they're going to win. Right now I'm the leader and I'm not quitting yet.

"I don't know if I can keep doing this for another four, five or six years but I'm going to try. I'm going to try until I'm 50," added the former world number one.

"Nowadays with equipment, with the ball going so far and with us working out very hard, we know how to work out now.

"I told everybody, when I show up and I know I can't win the golf tournament, I'm going to quit. But as long as I show up and know that I can win, I'm going to keep playing."

Although Singh has not won a major title since the 2004 PGA Championship, he completed the most lucrative campaign of his career on the 2008 Tour.

Best season

He triumphed three times in five weeks to clinch the FedEx Cup and the $10 million bonus in late September, describing the season as one of his best after contending with assorted injuries and a swing change over the last 18 months.

"I never gave up," Singh said. "I kept at it, hurt, not hurt, pain, it didn't matter. I was out there practising and believing in myself and doing it.

"At the end of the day, I came out up front and that shows that all the hard work has paid off. I'd rank this one of my best seasons, I think, considering what I went through."

Singh, who ended Woods's five-year reign as world number one in September 2004, has long been known as one of the hardest workers in the game.

Since turning professional in 1982, he has been a byword for dedication and once memorably warned a caddie that he opened up and closed the practice range, routinely hitting 500 balls in a day.

As he approaches 50, he no longer hits as many balls but he maintains a stringent fitness regime.

"You've got to keep your body fit and healthy," the three-times major winner said. "The kids out here (on tour), they're strong and they're getting better every year.

"So for me to keep up with them, I just need to be physically fit. I think my golf game is good enough to hold out. If I just keep strong and keep fit, I think I can still hold up."
