Davenport eyes one more grand slam

I think it's trying to win that last grand slam or another one that kind of keeps me excited about playing," Lindsay Davenport said.

After nearly 12 years on the professional circuit, Lindsay Davenport has the perfect excuse to quit tennis.

The 28-year-old Davenport has won virtually everything the game has to offer, is already rich beyond her dreams and is happily married.

She has also been plagued by injuries and briefly contemplated retirement but the easy-going Californian has no intention of hanging up her racket just yet.

Last year, seemingly in the twilight of her career, she overcame all her obstacles to finish 2004 as the number one player in the world.

It was the third time in six years she had ended the season on top of the rankings and gave her fresh hope that she can add to her collection of three grand slam titles.

"I've been fortunate enough to win a lot of tour titles, been fortunate enough to have a really consistent career but I think it's trying to win that last grand slam or another grand slam that kind of keeps me excited about playing," Davenport said in Sydney this week ahead of the Australian Open, which starts on Monday in Melbourne.

"Physically I feel like I'm in good shape. I hope that I hold up injury-wise and have worked hard off the court this season to try and physically be ready and hopefully I am."
