CARLSBAD, Calif. (AP) -- Martina Hingis is back in familiar territory for the first time in two months.

Hingis advanced to the semifinals of the TIG Classic with a 6-2, 6-4 victory over Dominique Van Roost on Thursday. It's her first semifinal berth since the French Open in June.

She lost the French final to Steffi Graf, then got bounced out of Wimbledon in the first round. She's playing a tournament for the first time in nearly a month.

``It just feels better being in the semis again. At Wimbledon, I just don't really know what I was doing there anymore,'' Hingis said. ``The confidence and the belief that you can do it again is growing match by match.''

In today's quarterfinals, top-seeded Lindsay Davenport takes on qualifier Anke Huber; No. 4 seed Venus Williams plays Sandrine Testud; and seventh-seeded Amanda Coetzer meets Amy Frazier. The Coetzer-Frazier winner plays Hingis.

Hingis, the No. 2 seed, lost just seven points on her serve in the second set against Van Roost, who lost the first set in 31 minutes.

``I played very well and focused from the beginning,'' Hingis said. ``Those games I won easily, I never struggled on my serve. I picked up on my game a little more.''

Van Roost, a Belgian ranked 15th in the world, pressed Hingis throughout the second set. In the fifth game, she had three chances to win before netting a forehand after the fourth deuce to set up a break point for Hingis. Van Roost then hit a smash long to trail 3-2.

Van Roost held serve after two deuces to trail 5-4, but Hingis won on the second match point when Van Roost's forehand service return went wide.

Testud defeated No. 6 Aranxta Sanchez-Vicario 6-2, 7-5 Thursday night.

Testud, a Frenchwoman ranked 14th, won 11 of the last 12 points, including breaking Sanchez-Vicario at love in the 11th game. Testud is in the quarterfinals for the second straight week, having lost to Coetzer last week at Stanford.

``I was not aggressive last week,'' she said. ``I wanted to make sure that I was aggressive against Aranxta. I just wanted to go for the shots.''

Sanchez-Vicario converted just one of 11 break points.

Huber outlasted Barbara Schett of Austria 5-7, 6-4, 6-4. Huber got into the main draw through qualifying, the first time she had to do so since 1990.

``I was thinking a long time if I was going to play, but I guess it was the best thing that happened to me. I played some matches, some very tough ones, and I won them,'' Huber said. ``If you haven't played for nine years, you don't even know how it is there. It's just different. You have to prepare for it mentally.''

Huber, ranked fourth in the world in 1996, is now 29th. She surprised eighth-seeded Nathalie Tauziat 6-3, 6-1 in the first round. In 13 tournaments this year, Huber hasn't advanced past the quarterfinals.
