BEIJING — Esther Vergeer won her 349th straight match Sunday, capturing the Paralympic gold medal in women's wheelchair tennis with a victory over Dutch teammate Korie Howman.

She won 6-2, 4-6, 7-6 (5) to extend a streak that has lasted 5 1/2 years.

"I mean, I am going to lose matches one day," she said. "But I was just really, really hoping it was not going to be today. I was just this close from losing this match, the most important match of my whole year."

Vergeer won double gold medals in Sydney and Athens. She will go for that again Monday in doubles with partner Jisek Griffioen. They face Americans Beth Arnoult and Kaitlyn Verfuerth in the final.

France's Florence Gravellier won the singles bronze, beating Griffioen 6-3, 6-4.

Fifty-six medals were up for grabs Sunday with 18 in swimming and the same number in track and field. Medals also were awarded in archery, road cycling, goalball, powerlifting and sitting volleyball.

South African swimmer Natalie Du Toit won her fifth and final gold, taking the 50-meter freestyle. Du Toit also won five gold medals four years ago in Athens.

Du Toit is one of two athletes in the Paralympics who also competed in the Olympics. At the Beijing Games, she finished 16th in the 10-kilometer open water swim. Her race was ruined when she lost her cap early and struggled to replace it.

"It's a relief from the disappointment (of the Olympics)," Du Toit said. "My goal was to get five golds, so at least I got one of the two things right."

Du Toit plans to train for both the London 2012 Olympics and Paralympics. She'll focus on the Olympic 800 freestyle and 10-kilometer.

Two American swimmers finished with four gold medals — Erin Popovich and Jessica Long. Both, however, failed to win a fifth gold Sunday. Popovich was second to American teammate Cortney Jordan in the 50 freestyle. Long finished fifth in another 50 freestyle for a separate disability class.

In the women's sitting volleyball final, China defeated the United States 25-14, 25-19, 25-15 to take the gold.

Oscar Pistorius, the South African runner known as "The Blade Runner," goes for his third gold Tuesday in the 400 meters, having already won the 100 and 200.
