Kenyan Pamela Jelimo claimed the Golden League's $1 million jackpot on Friday, while fellow Olympic champion Usain Bolt beat Asafa Powell to win the 100 meters at the Memorial Van Damme meeting. Croatian high jumper Blanka Vlasic missed out on a share of the jackpot after finishing second behind German Ariane Friedrich, but ahead of Olympic champion and home favourite Tia Hellebaut who surprisingly finished third. The 18-year-old Jelimo won the 800 meters in one minute 55.16 seconds, more than three seconds ahead of compatriot Janeth Jepkosgei and third-placed Kenia Sinclair of Jamaica. Earlier, Bolt powered past fellow Jamaican Powell in the 100 metres to set a new course record time of 9.77 seconds. Powell, who ran the joint second-fastest 100 of all time in Lausanne on Tuesday, finished in 9.83 after leading for most of the race until Bolt ran past him in the final 10 meters. Nesta Carter made it a Jamaican clean sweep by coming third in 10.07. Hussain Taher Al-Saba (7.96 meters) stood second to Miguel Pate of the US (8.02) in the long jump. Salim Sdiri of France finished third (7.92). There was further heartbreak for Vlasic - pipped for the gold by Hellebaut at this year's Beijing Games - when she failed on her final jump at 2.02 meters. Friedrich and Hellebaut also failed clear that height but the German won on the countback in one of the biggest shocks of the night having got over 1.97 on her first jump while Vlasic needed two attempts and Hellebaut three. In the women's 100 meters, Belgium's European champion Kim Gevaert marked her last ever appearance on home soil when she scorched to victory in 11.25 seconds. Amid the loudest roar of the night from the 50,000 capacity crowd, Debbie Ferguson of the Bahamas finished second and American Me'Lisa Barber was third behind the tearful 30 year-old Gevaert, who will retire at the end of the year. Elsewhere, Russia's Olympic champion Yelena Isinbayeva won the pole vault with an unimpressive jump of 4.72 meters, blaming a combination of tiredness after Beijing and the damp weather. American Jeremy Wariner overcame the wet and windy conditions to hold off Britain's Martyn Rooney to win the 400 meters in 44.44 seconds. Kenya's Paul Koech stunned Olympic and world champion Brimin Kipruto to win the 3,000 meters steeplechase while Kenyan Olympic silver medallist Eliud Kipchoge easily won the 5,000 in the opening race of the night. World champion Tero Pitkamaki, who finished third in China, gained revenge on Norway's Olympic champion Andreas Thorkildsen in the javelin, winning with a throw of 85.82 meters. Thorkildsen finished third behind Latvia's Beijing silver medallist Ainars Kovals. Belarusians test positive The president of the IAAF says the Belarusian silver and bronze medalists in the men's Olympic hammer throw have tested positive for doping and will be suspended. Lamine Diack told The Associated Press on Friday that Vadim Devyatovskiy and Ivan Tsikhan “were tested and it was positive.” The International Olympic Committee said Thursday it was investigating the two athletes, and that a disciplinary commission will meet at the end of the month to hear the case. The Belarus Athletics Federation said both Devyatovskiy and Tsikhan had denied the accusations. Jones released from prison Disgraced sprinter Marion Jones was released Friday from federal prison after completing most of her six-month sentence for lying about her steroid use. Jones left a halfway house in San Antonio around 8 A.M., said LaTanya Robinson, a community corrections manager for the federal Bureau of Prisons. Jones, who has a house in Austin, will remain on probation.
