(BEIJING, 18 August) -- Despair and disbelief filled the National Stadium when home-crowd favorite and defending 110m Hurdles gold medallist Liu Xiang of China failed to complete his first-round heat.

Another of the favorites in the Men's 110 Hurdles, Terrence Tramell of the United States, also failed to finish his heat after pulling his hamstring and failing to clear the second hurdle. However, world record holder Dayron Robles of Cuba had few problems progressing, leading his heat in 13.39 seconds.
Continuing on the brighter side, Irving Jahir Saladino Aranda of Panama made history by becoming the first Panamanian to win an Athletics Olympic gold medal when he added the Olympic Long Jump title to his 2007 world title with a leap of 8.34m.
Behind Saladino Aranda were Khotso Mokoena of South Africa, who grabbed the silver with a jump of 8.24m, and Ibrahim Camejo of Cuba, who took bronze with 8.20m.

Behind him, taking the silver and bronze, were 2007 world champion Kerron Clement and 2005 world championship Bershawn Jackson.
US discus thrower Stephanie Brown Trafton's first throw of 64.74m was good enough for gold in the Women's Discus Throw. Cuban athlete Yarelys Barrios's threw a 63.64m to take silver. And Olena Antonova of Ukraine grabbed the bronze, her first major medal, with a toss of 62.59m.
