LOS ANGELES, CA, U.S.A. – Lindsay Davenport will add another wonderful achievement to her already-impressive resume on Monday as she will finish 2005 ranked No.1 on the Sony Ericsson WTA Tour Singles Rankings. It is the fourth time the 29- year-old American has finished as year-end No.1, having also ended the 1998, 2001 and 2004 seasons on top of the official rankings.

With the Tour recently marking the 30th anniversary of its computer singles rankings (November 3, 1975), Davenport becomes only the fourth woman to finish No.1 at least four times, after Steffi Graf (eight times), Martina Navratilova (seven) and Chris Evert (six).

This week's season-ending Sony Ericsson WTA Tour Championships presented by Porsche (November 8-13) featured a battle for the year-end No.1 ranking between Davenport and former No.1 Kim Clijsters. Davenport had reached a Tour-best 10 finals in 2005, winning six titles and finishing runner-up at the Australian Open and Wimbledon. Clijsters, meanwhile, surged from No.134 in March (after missing much of last year with a wrist injury) to her current ranking of No.2, claiming nine titles including her first major, the US Open.

The year-end No.1 ranking would go to whoever performed better this week in Los Angeles out of the American and the Belgian. After two days of round robin play, Davenport had posted a 2-0 record without losing a set and thus securing a semifinal berth, while Clijsters failed to win either of her matches against Mary Pierce or Amélie Mauresmo. When Mauresmo defeated Elena Dementieva on Thursday it ruled Clijsters out of semifinal contention, and consequently dashed her hopes of finishing No.1.

"It's unbelievable to do it four times," said Davenport. "I wouldn't have felt last year that I would have a chance to do that again. But it's been a great year; I came close to winning a Grand Slam a couple of times. This is just a really nice way to end the season."

"Over her nearly 13-year pro career, Lindsay has proven to be one of the Tour's most enduring champions of all-time," said Sony Ericsson WTA Tour CEO, Larry Scott. "To achieve this feat four times over an eight-year period is phenomenal and is testament to the hard work she's put in over her entire career. Lindsay is a fantastic ambassador for women's tennis and I congratulate her on another standout year."

Davenport is currently spending her 87th non-consecutive week at No.1 (sixth all-time), having first reached the top spot on October 12, 1998. She is presently in her eighth different stint at No.1 and is one of only five women to have been ranked No.1 in both singles and doubles.
