Hingis's mixed doubles win with Ivo Heuberger helped Switzerland to a 2-1 win over the United States pairing of Davenport and Jan-Michael Gambill.

Hingis, whose new year's resolution was to regain the number one spot, gave the Swiss the lead with a 6-3, 5-7, 6-2 win over Davenport in the opening singles.

Gambill, one of the rising stars of American tennis, beat Heuberger 6-4, 6-4 and then Hingis and Heuberger settled the match with a workmanlike 6-3, 6-3 win over Gambill and Davenport.

Despite losing to the Slovak Republic yesterday, Switzerland will be guaranteed a berth in Saturday's final if they beat Sweden 3-0 tomorrow.

The defeat left the second-seeded Americans out of contention for a place in the final.
