FILDERSTADT, Germany -- Slovakia's Daniela Hantuchova overcame a second set lapse of concentration to beat Czech Daja Bedanova 6-2, 6-3 on Monday to reach the second round of the $625,000 Porsche Grand Prix.

"I felt really good out there and felt she couldn't really hurt me with anything," Hantuchova said. "It was a matter of me making too many mistakes when I lost those games. But I thought I was serving quite well and also returning well."

Hantuchova was the only seeded player in action on the opening day of the tournament, which drew 11 of the world's top 15 players.

Also victorious were Russia's Tatiana Panova, who earned a second round meeting with third seed Jelena Dokic by beating Silvia Farina-Elia of Italy 6-3, 6-2, and Anna Smashnova of Israel, who dismissed Switzerland's Patty Schnyder 7-5, 6-4.

Eighth-seeded Hantuchova lost to Bedanova in three sets in their only previous meeting in Antwerp earlier this year.

Hantuchova appeared to be on course for an easy victory in their second meeting as she swept the last four games of the opening set. She intimidated Bedanova with some winning returns and also struck a number of fine winners down the line.

But after easing through the first set, Hantuchova immediately dropped her serve in the second. And although she quickly levelled at 1-1, some whistling from the crowd disturbed her concentration for a while.

She had to fight off three break points at 2-2, but she eventually regained the upper hand and finished the match by breaking to lead 5-3 and claiming 12 of the final 14 points.

"I didn't put her under enough pressure as I did in the first set, but at the crucial time I was able to break her serve," Hantuchova said. "It was strange a few guys were whistling, but I just kept concentrating on my game.

Jennifer Capriati and Lindsay Davenport are the top-seeded players in the tournament. No. 1 Serena Williams withdrew last week.
