Kim Clijsters became the first Belgian to claim the world's top ranking when she beat second seed Lindsay Davenport 6-1, 3-6, 6-1 in the final of the JP Morgan Chase Open on Sunday.

"I always looked up to number ones Steffi Graf and Monica Seles and to be in the position now even though they held the ranking for so much longer is incredible," the 20-year-old said.

Clijsters, who took over the top spot from the injured Serena Williams, became the first player lead the rankings without winning a Grand Slam since the WTA Tour introduced the ranking system in 1975.

"When they said it on court, it gave me goosebumps." she said.

"Being number one reflects on the great season I've had so far. No one can take that away from me. It's something I'll always have on my resume."

A former number one herself, Davenport was full of admiration for her opponent.

"It's a huge accomplishment. Now everyone is going to start asking her when she's going to win a Grand Slam," Davenport said.

"But she has the goods to do it. She has a lot of game and hasn't even hit her peak yet."

EARLY LEAD

Clijsters jumped out to a 4-0 lead in the first set with a pinpoint service game, powerful groundstrokes and by attacking Davenport's second serve.

She then took the set when she ripped a backhand crosscourt past Davenport and then hit a twisting 84 mph second serve winner.

But three-times champion Davenport began to find the range with her big first serve and searing groundstrokes in the second set and took a 2-0 lead in the second.

But Clijsters broke back to 2-3 and then fought off two break points to even the set at 3-3 and appeared to be regaining control of the match.

However the tall American fought off four break points with a series of winners to hold to 4-3, broke again to go out to 5-3 and then levelled the match with a 107-mph service winner.

The players then took a 10-minute break between sets because of the heat. When they returned Clijsters raced out to a 3-0 lead.

The 27-year-old American recently received a second cortisone injection to treat neuroma, which has inflamed a nerve between the third and fourth toes on her left foot.

Davenport said she began to feel pain in her foot when trailing 1-3 at deuce and after that, she knew the contest was all but over.

"I had already dug myself too deep a hole at that point," she said.

"It wasn't like I had a game plan to come back and her shots were much more penetrating."

CELEBRATORY CAKE

After the match, Clijsters was presented with a large bouquet of flowers shaped into a number one and was given a cake with the inscription "Congratulations number one Kim".

Clijsters cut the cake herself and handed pieces out to fans at the Home Depot Center.

Her father Leo told her that almost her entire hometown of Bilzen was watching.

"There was a big band performing in our hometown but no one showed up because they were all watching the match," Clijsters said.

"They have always been very supportive and it's nice to able to give something back to them. This is a day I'll never forget."
