World champion Tyson Gay equalled the fourth fastest 100 meters of all time when he clocked an American record 9.77 seconds in the quarterfinals at the US Olympic trials on Saturday. The sizzling run followed an embarrassing mistake by Gay in the opening round in which he said he misjudged the finish line and needed a late surge to qualify. Only world record holder Usain Bolt and Jamaican countryman Asafa Powell, the former record holder, have run faster. Gay's time broke former world record holder Maurice Greene's 1999 national record of 9.79 seconds and overshadowed Muna Lee's surprising win in the women's 100 meters final. Lee clocked 10.85 seconds to upset former world champions Torri Edwards and Lauryn Williams. Edwards finished second and Williams third to make the US team for Beijing. Both clocked 10.90 seconds. Edwards had equalled the eighth fastest women's 100m ever with a time of 10.78 seconds in the semifinals. Marshevet Hooker, who had a wind-assisted 10.76 seconds on Friday, was a non-qualifying fourth and world 200 meters champion Allyson Felix took fifth. America's top shot putters also earned berths for Beijing. World champion Reese Hoffa won the event in 22.10 meters with world indoor champion Christian Cantwell second at 21.71m. Two-time Olympic silver medalist Adam Nelson was third at 20.89m. Hyleas Fountain dominated the heptathlon, winning with 6,667 points, the best score in the world this year. Gay went from a frightful opening run to America's best in less than three hours. He had a comfortable four-meter lead by midway the opening race, but slowed down after about 70 meters. The field closed rapidly and Gay, now behind, had to surge for the finish. Chambers looking good British sprinter Dwain Chambers twice ran within the ´A' qualifying time for the Beijing Games on Saturday, clocking 10.06 seconds to win the 100 meters at the EnBW Weltklasse meet in Germany. Chambers had run 10.14 in his heat earlier Saturday, beating the qualifying time of 10.21 required to run in the Olympics for the first time since returning from a two-year doping suspension earlier this year. Chambers remains barred from Beijing because of a lifetime Olympic ban under guidelines set down by the British Olympic Association, but Saturday's result is likely to strengthen his case for appealing that ban. – Reuters __
