The Olympics Stadium announcer made a request to "clean up the carnage" after a series of heats in which runners banged into, somersaulted over or simply crash landed into hurdles in the men's 110m heats Tuesday morning. But the loudest fall in the stadium was that of China's Liu Xiang. China's only great hope in track and field stumbled and fell into the first hurdle Tuesday, failing to qualify. This fall isn't a first for the former world-record holder and 2004 champion. Four years ago in Beijing, his Olympics ended after two full strides, when he withdrew from his preliminary heat with right foot and hamstring injuries. Among those who didn't fall? Americans Jason Richardson, Jeff Porter and Aries Merritt all advanced to the semifinals in the 110m hurdles.
