ZURICH, Switzerland (Ticker) - World No. 1 Martina Hingis beat Lindsay Davenport, 6-4, 4-6, 7-5, in today's final of the Swisscom Challenge, bringing the American's win streak in Switzerland to an end while collecting her first title on home soil.

An hour later, Hingis was back on the court with partner Anna Kournikova to cap off a productive afternoon by winning the doubles title, 6-3, 6-4, over American Kimberly Po and Frenchwoman Anne-Gaelle Sidot.

Hingis completed the tournament sweep for the second straight tournament after capturing both titles last week in Filderstadt, Germany.

It was the homecoming Hingis had been looking for ever since she made her professional debut at this event as a 14-year-old.

Despite living just a few miles from the Schluefweg Arena where the $1 million tournament was staged, Hingis had never enjoyed much of a home-court advantage. She reached the final two of the last three years, losing both times.

"It means a lot to win a home tournament for the first time and twice as much here," said Hingis, after collecting a WTA Tour-leading seventh title of the season and 33rd of her career. "It's different, it's overwhelming. It's not just the victory but also the first time winning here at home after losing two finals.

"Victories like today do wonders for my self-confidence. I sometimes felt like I was in a Formula One race and when at the end it's such a great feeling, especially since I desperately wanted to win this tournament."

While the tournament was played in Hingis's backyard it was the second-ranked Davenport who always seemed more at home in Switzerland, having won four consecutive tournaments and stringing together a win streak of 20 matches.

Since losing her debut match to Italy's Linda Ferrando in 1992, Davenport had been unbeatable on Swiss soil, taking back-to-back European Open crowns in nearby Lucerne in 1993-94 and Zurich titles in 1997-98.

Playing in her first tournament since being forced out of the Sydney Olympics in the second round with tendinitis in her left ankle, Davenport looked set to extend her Swiss streak as she broke Hingis to open the match, silencing the soldout partisan crowd as she raced to a 2-0 lead.

But Hingis broke back to level the contest at 2-2 and again at 5-4 to take the first set.

Behind a booming serve that produced 11 aces, Davenport recorded the only break of a tight second set to extend the match.

When the 24-year-old American broke to take a 4-3 lead in the third, Hingis and the crowd slumped. But a determined Hingis immediately broke back as the match ended in a succession of high-risk shots and four consecutive breaks.

The Swiss then held serve and claimed a fifth break and the title when Davenport drove her return into the net.

"Those are tough ones to lose," said Davenport, who has reached 10 finals this season but won just twice. "I fought to stay in there.

"I thought the big game was at 4-3. I was serving at 30-love and she came up with a couple of good shots and we were back at 4-4. It would have been nice to get ahead at 5-3 and have a chance to return and serve for the match. But I hung in there when I wasn't playing well and it was just at the end that I couldn't win that last game. I was probably going for a little too much and trying to hit it too good instead of just relaxing and trying to hit a little smoother."

Sunday's final marked the fourth time this year Hingis and Davenport had met to decide a title, with Davenport winning at the Australian Open and Indian Wells and Hingis prevailing at the Ericsson Open and Zurich. Their final at Scottsdale, Arizona was washed out by rain.

It was Hingis's second consecutive win over Davenport but the American continues to hold an edge in head-to-head meetings, 11-9. The victory, however, allowed Hingis to tighten her grip on the No. 1 ranking.

"It was a match I could have won but I didn't," Davenport said. "Losing to good players and players at the top of their games is tough but I'll get over it."

Hingis will take next week off while Davenport has received a wild card for this week's event in Linz, Austria. But even if the American were to win in Austria she cannot take the top spot away from her Swiss rival.
