Belgian Kim Clijsters maintained her 100% record against American Chanda Rubin to claim a fourth victory in five years at the Seat Open in Luxembourg.

The win, as well as seeing this year's French and US Open runner up return to world number one at the expense of compatriot Justine Henin-Hardenne when the new rankings list is released on Monday, is Clijsters' eighth title of 2003 and 18th in her career.

Clijsters dominated the opening set 6-2, and completed a one hour, 22 minute victory by recovering from 4-1 down to take the second 7-5.

Rubin has now lost all six meetings between the two, and has not won a set from Clijsters since their first meeting at the 2000 Hobart final.

Clijsters said: "I can't believe I've won this tournament now four times.

"I came here as a 16-year-old, just starting out on the Tour and ever since it has been a big part of my career.

"And it sounds weird to say I've won eight titles this year! I've played a lot, but I've managed to stay consistent pretty much the entire season, so for me I'm just hoping I can continue that.

"After the first set Chanda really picked up her game. She took advantage of her opportunities, while my level might have dropped a little bit.

"But I kept my focus even when I was down 4-1 and I told myself I still had a chance to win that set."

Rubin was understandably disappointed with her display, especially with her second set collapse, but signalled her intention to come back stronger in 2004.

"It's always great to get to a final, but I suppose I'm a little disappointed I at least didn't push it into a third set," she added.

"I put myself in a really good position, going up 4-1, but I just didn't keep it going. Kim raised her game a bit and I just didn't respond well enough.

"I'm very happy with the way my season has gone. I've won a couple of titles, but over the break I'm going to work on my fitness and on the parts of my game that I need to improve even more.

"I'd like to just keep my play going into 2004, maybe with some better results at the Grand Slams."
