SINGAPORE (AFP) - Top men's seed Taufik Hidayat crashed out and women's world champion Wang Lin departed in tears in a day of carnage at the Singapore Open badminton tournament on Thursday. Hidayat, the 2004 Olympic gold medallist and a two-time Singapore winner, led a parade of seeds out of the men's draw when he was shocked by China's up-and-coming Wang Zhengming, 21. World junior champion Viktor Axelsen stunned his idol, China's Bao Chunlai, while South Korea's Lee Hyun-Il sent third seed Chen Long packing and eighth seed Park Sung-Hwan was humbled by China's Chen Jin. Hidayat fought back from a set down against Wang but his defence proved unable to cope with the heavy-hitting Chinese, who ran away with the decider to take it 21-16, 20-22, 21-13. The upset ends a stormy tournament for the volatile Hidayat, who had slammed Indonesian media coverage after he did not attend a pre-tournament press conference. "Today I played very badly," he said afterwards. "I think tomorrow I'll go back to Indonesia and prepare for (next week's) Indonesian Super Series." But the day's biggest heartache was reserved for Wang Lin, whose Olympic dream appeared in tatters after a recurrence of a serious knee injury which had kept her side-lined for seven months. Wang, who was on the comeback trail after anterior cruciate surgery, was 12-8 down to top-seeded compatriot Wang Shixian in the tournament's second round when she abruptly pulled out. Singapore Open officials said Wang had aggravated her damaged left knee and requested hospital treatment. If the knee has broken down, it almost certainly puts paid to her hopes of reaching next year's London Games. The 22-year-old was crowned world champion in Paris last August but dramatically fell to earth when she suffered the career-threatening injury in her very next match, in round one of the China Masters. Wang returned to action in April and has clawed her way back from 103 to 64 in the world, but had to go through qualifying to reach this week's main draw. She said the thought of next year's Olympics was what drove her comeback.
