Women's No. 1 Spot Up for Grabs

DOHA, Qatar (AP) -- After months of debate about who is more deserving of the No. 1 ranking, Serena Williams and Dinara Safina will settle the issue on the court at the WTA Tour's season-ending Sony Ericsson Championships.

Safina recaptured the top ranking from Williams on Monday, but the margin is so slim that the player who performs better at this week's tournament in Doha will end the year at No. 1.

Safina has held the top spot for 26 weeks this year, but the Russian has faced persistent questions about whether she's worthy of the title without having won a Grand Slam tournament. Williams won her 11th major title at Wimbledon this year, after also taking the Australian Open.

"It would be awesome," Williams said Monday about the prospect of ending 2009 atop the rankings. "It would be really cool. But I would have to win."

Actually, she only has to win one more match than Safina. If both players have equal results, Safina keeps the top ranking.

The eight-player tournament starts Tuesday with a round-robin stage, with the top two players from each group advancing to the semifinals. Williams and Safina are in different groups, meaning they will not face each other until a potential match in the knockout rounds.

Williams was drawn with her sister Venus and Russians Svetlana Kuznetsova and Elena Dementieva. The other group consists of Safina, former No. 1 Jelena Jankovic of Serbia, Victoria Azarenka of Belarus and Danish teenager Caroline Wozniacki.

Safina has 7,731 points in the latest rankings to lead Serena Williams by 155 points. Each win in the round-robin stage here is worth 160 points.

The other six players also have plenty to play for.

The total prize pool is $4.55 million and the champion receives $1.55 million if she completes the tournament undefeated-with $100,000 knocked off for each loss in the round-robin stage.

Venus Williams is the defending champion, while Azarenka and Wozniacki are competing in the event for the first time.

The Williams sisters-who are also playing in the doubles tournament-are the only previous champions, and Venus said the money isn't the only reason she's looking for a repeat.

"Last year was definitely a monumental moment," she said. "I never thought it would feel so good to actually win the year-end championships. It was definitely a surprised feeling at the end. I would love to feel that again."
