Canadian Stephan Wojcikiewicz advanced to the second round of the badminton world championships on Tuesday, while Anna Rice, the top women's player in the country, lost her match.

Wojcikiewicz, an Ottawa native, defeated Dmytro Zavadsky of Ukraine 21-18, 21-19 in the men's singles draw in Paris.

In the second round, Wojcikiewicz will face Chen Ong Zhao of Singapore, who upset 14th-seeded Chetan Anand of India 21-14, 21-18.

Rice lost to Pui Yin Yip of Hong Kong 21-19, 21-13 in the second round of the women's singles draw. In mixed doubles, Calgary duo Toby Ng and Grace Gao lost 21-8, 21-16 to Japan's Noriyasu Hirata and Maeda Miyuki.

In men's singles, second-seeded Peter Gade of Denmark and fourth-seeded Chen Jin of China reached the second round.

Chen, a 2009 world runner-up, beat Ville Lang of Finland 21-14, 21-14 while European champion Gade cruised past Daniel Paiola of Brazil 21-10, 21-7.

Chen will next face Kestutis Navickas of Lithuania, who rallied past Kieran Merrilees of Scotland 15-21, 21-13, 21-14.

Gade will have a trickier match against South Korea's Shon Wan Ho, ranked 19th in the world, who defeated Hu Yun of Hong Kong 21-18, 21-13.

"He's been teasing some of the best ones," Gade said about Shon. "I have to play well to beat him. I need to be patient. He's a strong defensive player, I need to keep my attack a bit back."

The Dane leads 2-0 against Shon but was each time stretched to three sets.

'Hot in here'

Asked about complaints by several Asian players on Monday about the heat inside Pierre de Coubertin Stadium, Gade said he understood — to a point.

"It's an intimate stadium, it's got to be hot in here," Gade explained, "but we've been used to playing in hot venues for a long time, even though there's air conditioning in Asia.

"But you have to keep in mind that in the long games the heat may have a bit of an effect on you."

Meanwhile, top-seeded Wang Yihan of China began her bid for her first women's singles world title with a convincing victory in her opening match.

Following a first-round bye, Wang beat Porntip Buranaprasertsuk of Thailand 21-12, 21-19 to move into the third round.

Wang has held the world's top ranking since late last year, but she hasn't won a title since November and been susceptible to upsets this year.

She lost a classic final to Tine Baun of Denmark at the All England Championships, then crashed out early in the Swiss Super Series, and was upset in the Uber Cup final, in which China conceded a first title to South Korea.

Next up is Eriko Hirose of Japan, and a looming quarter-final against seventh-seeded Lin Wang of China or Yip Pui Yin of Hong Kong, who beat Wang at the Swiss Super Series.

Hirose beat Maria Febe Kusumastuti of Indonesia 21-14 21-18.

Lin, the bronze medal at last year's worlds in India, defeated Maja Tvrdy of Slovenia 21-7, 21-18.
