The top-ranked Hingis was pushed to three sets, but improved to 10-0 lifetime against her French opponent with a 7-5, 5-7, 6-2 quarterfinal victory today at the $1.08 million German Open.

Seeking her second straight title at this event, Hingis posted her fourth win over the fifth-seeded Testud this year. Hingis, who regained the No. 1 ranking on Monday, will battle third seed Conchita Martinez of Spain in Saturday's semifinals.

Martinez, the 1998 champion, dumped unseeded countrywoman Gala Leon Garcia, 6-4, 6-2, to reach her fifth semifinal of the season.

Hingis, 19, is seeking her WTA Tour-leading fifth title of the season and second in as many weeks in Germany. The Swiss teenager claimed last week's Betty Barclay Cup at Hamburg and one day later reclaimed the top spot in the WTA rankings from rival Lindsay Davenport.

Local favorite Anke Huber was stopped in her quest to crack the top 10 in the WTA rankings for the first time since 1997 as 10th seed Amanda Coetzer of South Africa dismissed the eighth seed, 6-4, 6-4.

A semifinalist here in 1997, Coetzer will meet unseeded countrywoman Joannette Kruger in the other semifinal. Kruger outlasted Elena Dementieva of Russia, 2-6, 6-3, 7-6 (7-5), to advance to her second semifinal of the year.

First prize at the 93rd German Open is $166,900. Only the U.S. Open (113), Wimbledon (106) and the Canadian Open (100) have been held longer among women's tournaments.
