The fourth seed, Mauresmo improved her season record to 31-2 with a 6-4, 7-6 (7-5) victory, her second win over Hingis in as many meetings.

Mauresmo, who topped the Swiss star in the semifinals of the German Open, became the first player to defeat Hingis in consecutive tournaments since Lindsay Davenport in 1999.

"I played a good match. I was there mentally and physically in the important moments," Mauresmo said. "We know each other's games very well. She likes to dictate the game and I was trying not to let her do it."

Mauresmo will seek her Tour-leading fifth title of the year when she meets No. 14 Jelena Dokic of Yugoslavia on Sunday. Dokic surprised third seed Conchita Martinez of Spain, 6-3, 6-2, in the other semifinal.

Hingis was defeated one day after becoming just the third player in WTA Tour history to surpass the $16 million mark in career earnings by downing Spain's Arantxa Sanchez-Vicario.

The 18-year-old Dokic, a semifinalist at Hamburg, Germany two weeks ago, will seek her first career title Sunday.

"It's a big event, of course," Dokic said of her first final. "But I play match by match so I don't really think of it."

Dokic had lost all five of her previous meetins with Martinez, and only once had taken a match with her to three sets.

Mauresmo won her only previous meeting with Dokic at Moscow last year.

First prize at the $1.2 million event is $176,000.
