Hong Kong's former world number one Wang Chen suffered her third defeat in just five weeks at the hands of the 2000 Sydney Olympics silver medallist Camilla Martin, bowing out in the quarter-finals of the Denmark Open in Aarhus. Wang, beaten by Martin in the last eight of the Indonesian and Malaysian Opens, suffered the same fate in Martin's home tournament, claiming she had never really acclimatised after her 11-9, 11-1 defeat. 'I was a little tired as I have trouble getting over the jetlag here, and also the food is very different,' said Wang, who has now lost seven times in a row to Martin in Grand Prix tournaments. Wang, who did beat the 29-year-old Dane in last year's Uber Cup (the women's world team championship) in Guangzhou, must have felt she had a chance to end her individual misery against Martin who had been dragged into a gruelling three-set affair in the previous round by South Korean Seo Yoon-hee. But the Dane, who will retire after the Athens Olympics, said playing in her own back yard carried her through both matches. 'I feel at home here in my hometown of Aarhus, and it really lifts my spirits to play here. The public helped,' Martin admitted. 'I don't think I would have made it if I had played the Korean in the Far East. Against Wang I was a little slow on court and probably missing 10 per cent of my speed yet, fortunately it is not the only thing in a badminton match.' Meanwhile, as she has done for most of her career, Martin found herself surrounded by Chinese stars in the last four with Gong Ruina her semi-final opponent and either Zhou Mi or Zhang Yining waiting in the final. The mainland's domination of the men's singles was undermined by an elbow injury suffered by world number one Chen Hong, that forced him to quit during his quarter-final with Malaysia's Wong Choong Hann. As a result both semi-finals pitted China against Malaysians with Lin Dan due to face Wong, while the unseeded Chen Yu was to square up against Mohd Roslin Hashim.
