World squash champion Nicol David kept alive her unbeaten streak and regained her Asian Games title by downing defending champ Rebecca Chiu 9-0, 9-3, 9-3 on Thursday.

Ong Beng Hee completed the gold-medal double for Malaysia when he rallied to defeat teammate Mohamad Azlan Iskandar 5-9, 9-1, 10-9, 9-5 in the men's final.

David extended her winning stretch to 36 matches and seven titles since July.

"I'm just ecstatic. This is the last event of the year and I wanted to go out with a bang," David said. "I did it."

She gave up service only once in the first game, then allowed Chiu back to 5-3 in the second before again taking control.

Chiu stayed even with David to 3-3 in the final game before David turned it on again, winning the last six points.

The 23-year-old Malaysian, who won the Asian Games in 1998, was upset in the 2002 final by Chiu. The defeat was so crushing for David that she took four months off to recover and regain her focus.

"It was about the transition from juniors to seniors for me," she said of the break. "It made me ready to go and be hungry again. Four years later here I am, world champion."

David, who trains in Amsterdam, is fresh off successfully defending her Women's World Open crown last month against Australia's Natalie Grinham in Belfast.

Chiu, ranked 15th in the world and a world junior champion, conceded she was no match for David this time.

"She's much better than me," Chiu said. "Silver was my goal. I'm happy to have my holiday now."

In the quarterfinals, David needed just 19 minutes to defeat South Korea's Park Eun-ok 9-0, 9-0, 9-4, and then cruised to the final by beating Hong Kong's Pui Hin 9-0, 9-1, 9-0.

David said the level of competition at the Asian Games should put the squash world on notice that Asia is a power to be reckoned with.

"The energy level at the games is really high," she said. "Asia is really taking off."

In the all-Malaysian men's final, Ong, who is ranked 18th worldwide, rallied to beat the more fancied Azlan, ranked 13th, after dropping the first game.

"I was very nervous," Ong said. "I think he was very nervous, too."

He noted that the two are used to playing each other, however.

"It's hard because we're best friends," he said. "We train together, we travel together, we play together."

"I just hit too many errors, made too many mistakes," Azlan said. "I've been mentally tired. But the best athletes have to back it up in every match. The objective is to win _ simple."
