LAUSANNE (Switzerland) (AFP) - Jamaica's Asafa Powell on Tuesday ran the second fastest ever time in the 100m at a meeting in Lausanne where Olympic hurdles champion Dayron Robles failed to win. And three-time Olympic champion Usain Bolt clocked 19.63sec in his favourite event, the 200m, for the fourth-fastest ever time. Powell's time of 9.72sec at this IAAF Super Grand Prix event was 0.03sec outside the 9.69 world mark which compatriot Bolt set at the Beijing Games on August 16. On that occasion, Bolt had shaven down his original mark of 9.72 set on May 31 in New York. Powell shot out of the blocks and quickly sped ahead of Walter Dix, the Olympic bronze medallist who timed 9.92sec. Powell, who could only manage fifth in Beijing, said on arrival in Lausanne on Monday that he was on form and hoped to beat his personal mark of 9.74sec, set on September 7 last year at Rieti in Italy and which at the time was a world record. "I came here full of confidence," he said moments after his win. "The track is fabulous and the fans just great." Last Sunday Powell had timed 9.87sec in rainy conditions at Gateshead in northern England while on Friday at the IAAF Zurich Golden League meeting in Zurich Bolt won in 9.83. Powell added: "After all the problems I have had this year I am really overwhelmed by this performance. To get a personal best is great." The 25-year-old has had physical problems and, to cap the lot, the entrance on to the scene of Bolt in the 100m event made things tougher. American David Oliver clocked 13.02sec in the 110m hurdles to beat Cuba's Beijing champion Robles, who managed 13.17. Oliver, the bronze medallist from China, also beat Robles on June 1 in the first leg of the IAAF Golden League in Berlin. Robles, who had been hoping to improve on his 12.87sec world record, was on target to set a new mark at the race's midpoint but, as Oliver fought back, he lost his composure and even hit the 10th and final hurdle. "I had come to run fast," said the Cuban afterwards. "But sometimes these things happen." Bolt, the 100m, 200m and 4x100m relay winner in Beijing, is still in scintillating form. Though he did not get near his world record of 19.30sec set in China, his 19.63sec in Lausanne was well under what was once a formidable barrier of 20sec. Bolt's time equalled that of American Xavier Carter two years ago on this same track. "Asafa proved just before that the track here was fast," said Bolt afterwards. "With the support of a lively crowd, it's fantastic." Jamaica is a country of top sprinters and women's 100m Olympic champion Shelly-Ann Fraser was also in good form, winning in 11.03 ahead of compatriot Kerron Stewart, who ran 11.06. In another performance of note, reigning 400m Olympic champion Lashawn Merritt of the USA went under 44 seconds (43.98) for the third time.
