China's Yang Fan, 19, made a dream international debut this week when he swept all three gold medals in the men's 62kg category at the World Championships in Thailand.

Despite having never competed in an international event, the world number one put on a confident display of lifting, soaking up the pressure of a close contest to win the snatch (142kg) and the clean and jerk (173kg) to take the overall gold medal with a total of 315kg.

North Korea's Im Yong-su matched Yang's lifts but, being the heavier of the two lifters by a mere 140 grams, had to settle for three silvers.

Triathlon - Champion suffers setback

World triathlon champion Tim Don said his hopes of qualifying for the 2008 Olympic Games had suffered a serious setback when he broke his left elbow in a crash in Beijing.

Briton Don, 29, who won the world title in 2006, fell heavily and suffered his injury on the bike section of last Sunday's Triathlon World Cup. Don has not yet achieved the qualifying standard for the Beijing Games but has one final opportunity to do so at the Madrid World Cup event next May.

He won an appeal in May this year against a three-month suspension, handed out shortly after he became world champion, for missing three doping tests.

Tennis - Doubles specialist retires

Argentina's Paola Suarez has retired from tennis after a career in which she won 44 doubles titles, including eight grand slams.

"It's the end of an era," Suarez, 31, told Argentine television. "It's time to start another life."

Suarez won 30 of her doubles titles, including all eight in grand slam tournaments, with Spain's Virginia Ruano Pascual and the pair reached the top of the world rankings in 2002.

Her grand slam doubles title tally with Ruano Pascual ran to four in the French Open, three in the US Open and one in the Australian Open. She never won at Wimbledon.
