For the fourth straight tournament, Hingis and Davenport will square off. The pair have contested the final of the Australian Open, Scottsdale, which was not played due to rain, and Indian Wells. Davenport, the winner of the two titles, leads their head-to-head series, 11-7, having won five in a row and eight of the last 10, dating back to February, 1998.

Not since the days of Chris Evert and Martina Navratilova have the world's top two players faced off against each other with such regularity.

Today's match is scheduled to begin at 4 p.m. EST. A first prize of $350,000 is at stake.

Davenport, the second-seeded American, reclaimed the No. 1 ranking from Hingis with her semifinal victory over 12th seed Sandrine Testud of France on Thursday night. She begins her third stint at the top spot officially on Monday, when the new WTA Tour singles rankings are released.

The 23-year-old Davenport is on a 21-match winning streak, the longest since Hingis went 37-0 to start the 1997 season. She has won 24 of 25 matches to start the season, losing only to Amelie Mauresmo in the Sydney International final in January.

The reigning Australian Open and Wimbledon champion, Davenport is seeking her 29th career title to tie Tracy Austin at No. 12 on the all-time list.

Hingis, the 1997 champion from Switzerland, improved her season record to 25-3 with a 6-0, 6-0 semifinal triumph over No. 7 Monica Seles on Thursday and will look to claim her 28th career singles title and her second of the season.

On Sunday, second seed and two-time champion Pete Sampras of the United States and No. 6 Gustavo Kuerten of Brazil will meet in the men's final. First prize is worth $410,000.
