The victory should give the 24-year-old Davenport, who has been plagued by injuries this season, a boost for this week's Chase Championships at Madison Square Garden, where she also is the defending champion.

After outlasting Hingis in the hotly-contested first-set tiebreaker, Davenport jumped to a commanding 5-1 lead in the second set. She appeared ready to close out the match after rallying from a 15-40 deficit on her serve with a pair of aces.

Davenport had her first match point when her opponent hit into the net. But Hingis made a valiant comeback, breaking Davenport twice to get to 5-4.

However, the Swiss Miss was unable to complete the comeback while serving as she sailed a ball long to hand Davenport the victory and her fourth straight title, excluding the Olympics, on her second match point.

Davenport, seeded second this week, improved her career record against Hingis to 12-9, with the last 15 meetings coming in championship matches. She has won three of five meetings this year after losing the previous two and earned a winner's prize of $87,000.

Hingis had a good streak of her own halted today. She had won 15 consecutive matches since her semifinal loss to Venus Williams at the U.S. Open. Hingis won titles at the Porsche Tennis Grand Prix, Swisscom Challenge and Kremlin Cup since her last defeat.

This year, the 20-year-old has won 73 of 82 matches, more than $14 million and eight singles titles to increase her career total to 34.
