Ethiopia's Kenenisa Bekele claimed his fourth successive 10,000m world title with a stunning performance in Berlin. Bekele, who has never been beaten at the distance, set a new championship record of 26 minutes 45.11 seconds. Shelly-Ann Fraser led a Jamaica one-two in the women's 100m in 10.73 seconds, with Kerron Stewart in second. But defending champion Yelena Isinbayeva failed to clear a height in the women's pole vault final, allowing Poland's Anna Rogowska to win gold. Bekele put in a savage kick at the bell to leave Zersenay Tadese of Eritrea, who had led for 13 laps, in his wake. Tadese took silver in 26:50.12, and Moses Dniema Masai of Kenya earned the bronze in 26:57.39. With his win in Berlin, Bekele equalled the four 10,000 world titles Haile Gebrselassie won over the distance. Olympic champion Fraser, whose time was the joint third best in history, made a flying start and just managed to hold off a late surge by Stewart, who clocked 10.75. American champion Carmelita Jeter was third in 10.90. Russia's Isinbayeva, whose world record stands at 5.05 metres, failed at one attempt at 4.75 and then two at 4.80. Rogowska, who also beat Isinbayeva at a recent meet in London, cleared 4.75 to finish ahead of Chelsea Johnson of the United States and Monika Pyrek of Poland, who shared the silver with vaults of 4.65. Isinbayeva had won every major title since winning gold at the 2004 Olympic Games in Athens. "I have no proper explanation for what happened," said Isinbayeva. "Everything was perfect, I was confident and I cleared 4.70m in the warm-up. "I do not regret I did not start at lower heights because even if I cleared 4.65 it would mean nothing. "This competition was important to me but I hope that will encourage me to be great in London in 2012. I hope I will recover from this." Marta Dominguez of Spain, the silver medallist in 2001 and 2003, won the women's steeplechase in a time of nine minutes 7.32 seconds. Dominguez raced past Yuliya Zarudneva of Russia in the final 100m, meaning Zarudneva took silver in 9:08.39 and Milcah Chemos Cheywa of Kenya picked up the bronze in 9:09.57.
