China claim second gold

Shanghai - China blew away the competition with an emphatic display of diving on Sunday to make it two World Championships gold medals out of two as they chase a historic clean sweep.
Olympic champion Huo Liang shrugged off the loss of long-time partner Lin Yue to injury as he combined perfectly with newcomer Qiu Bo in the 10m synchro - and claimed his third straight world title in the event.
Germany's Patrick Hausding and Sascha Klein claimed silver and Ukrainians Oleksandr Gorshkovozov and Oleksandr Bondar were third.
British individual 10m world champion Tom Daley, 17, grieving the loss of his father to cancer just two months ago, was placed sixth alongside partner Peter Waterfield.
China also won the tournament's first gold, the women's 3m synchro, on Saturday to make the early running in their first world championships on home turf - three years after they topped the medals table at the Beijing Olympics.
China, hosting the biennial championships on an impressive, purpose-built site in Shanghai, are gunning for the first ever diving gold medal sweep after missing only one at the 2008 Olympics and winning seven out of 10 in 2009.
The hosts are also predicted to challenge Russian synchronised swimming queen Natalia Ishchenko, who is chasing her 10th world championships gold medal in the women's technical solo later on Sunday.
In the 10m synchro final, Huo and Qiu executed a breathtaking backwards 3.5 somersault in the pike position for their fourth dive to gain 91.8 points and stamp their class on the event.
American David Boudia, a 2009 silver medallist, and his partner Nick McCrory rued a botched fifth dive which kept them out of the medals, despite placing second in the preliminaries.
Earlier, Wang Han and Shi Tingmao finished first and second in the women's 1m springboard to maintain China's 100 percent record in the championships' diving preliminaries. The final will be contested on Tuesday.
But the event proved a non-starter for German competitor Tina Punzel, who slipped on her second dive and flopped into the water near-horizontal, earning her just six points from a possible 100.
On Saturday, highly decorated Wu Minxia coaxed injured 20-year-old He Zi through the women's 3m synchro to claim her fifth gold medal in the event, and the first since the retirement of her illustrious former partner Guo Jingjing.
The 16-day event formally opened with a colourful opening ceremony late on Saturday with water polo and synchronised swimming competition also under way on Sunday. The blue-riband swimming events start on July 24.
But the tournament has been overshadowed by a high-profile doping case involving Brazilian swimming star Cesar Cielo, with officials tightening their drug-testing regime in a bid to catch cheats.
