Former world champion Taufik Hidayat rallied to beat unseeded Hsieh Yu Hsin of Taiwan 19-21, 21-19, 21-9 in the second round of the badminton world championships Wednesday.

Hidayat is the only Indonesian left in the singles after eighth-seeded Simon Santoso pulled out of the men's draw because of a back injury and Adrianti Firdasari lost 13-21, 21-15, 21-18 to South Korea's Kim Moon Hi in the women's draw.

It was a rough day for Canada as David Snider of Winnipeg, Stephan Wojcikiewicz of Ottawa and Charmaine Reid of Calgary were all eliminated by losing their second-round matches.

Snider lost 21-13, 21-13 to 10th-seeded Bao Chunlai of China while Wojcikiewicz went down 21-16, 14-21, 21-17 to Chen Yong Zhao of Singapore.

Reid was ousted 21-15, 21-10 by third seed Wang Xin of China.

China's contingent moved into the third round intact, with three men and four women still having a shot at the singles title.

"I'm lucky. The control was not good in the first set," Hidayat said after Hsieh was two points away from winning the match.

Hidayat said he was a bit too confident going into the second round as he had won all four previous matches against Hsieh. But he claims he doesn't feel any added pressure in carrying his country's hopes.

"I don't feel pressure," Hidayat said. "I have more motivation because I'm the only man in singles from Indonesia."

Defending champion Lin Dan of China beat Henri Hurskainen of Sweden 21-13, 21-15. He could meet top-seeded Lee Chong Wei in the semifinals. The Malaysian cruised past compatriot Muhammad Hafiz Hashim 21-16, 21-16 in 26 minutes to earn his 18th straight win.

Lee is chasing his first world title and hopes to end the dominance of the third-seeded Lin, who is the only player to have won three straight world titles.

In women's singles, second-seeded Saina Nehwal of India was stretched but overcame Chen Hsiao Huan of Taiwan 20-22, 21-15, 21-8.

The 20-year-old Nehwal is having a breakthrough season but she was not completely immune to pressure in her opening match after receiving a first-round bye, saying she felt "a little nervous."

"Being the No. 2 seed for the first time in the world championships, it was a little bit tough to accept," Nehwal said. "But then I was ranked No. 1 in the Super Series, so that was OK."
