Tyson Gay has again thrown down the gauntlet to Usain Bolt before the world championships by reinforcing his status as the current fastest man in the world.
After getting off to a powerful start at the Diamond League meeting, Gay finished the 100m in 9.79 seconds, ahead of the Jamaican Asafa Powell and his American compatriot Michael Rodgers.
It was Gay's second-fastest time this year, while Powell and Rodgers recorded season's best times on a fast track with a tailwind just within the legal limit of two metres per second. Kim Collins, in fourth, beat his own St Kitts & Nevis national record with 9.97sec.
Gay, having shrugged off long-standing injury worries, said consistently recording fast times after so many years of frustration was key before a 100m at the world championships in Moscow that is shaping up to be an epic clash.
"It felt good. It's all about consistency and staying healthy because that's the key to success at this level," said Gay. "Sometimes you wish you could take advantage of the wind a little more but at the same time I felt good."
Gay had already served notice to his long-time rival Bolt that he may not have it all his own way in his attempt to regain his world title in August by recording the fastest 100m sprint in the world this year, with a time of 9.75 at the US trials last month. Before this race he said he hoped this season to beat his personal best of 9.69. He set that time in 2009, the last season when he was completely injury free, and claimed to be feeling as confident as he did then.
The 30-year-old American, a world champion in 2007 and the second-fastest 100m runner of all time behind Bolt, had overcome Powell in five of their previous six encounters and again beat his Jamaican rival into second place. Powell finished second in 9.88 and Rodgers was third in 9.96.
On a night of mostly underwhelming performances from the British contingent only the long jumper Shara Proctor, who finished third with a season's best jump of 6.92m, and the 110m hurdler Tiffany Porter, who recorded her season's best time of 12.53 in finishing fifth, could be truly satisfied with their work.
In the women's 400m Christine Ohuruogu again faced the in-form 2011 world champion Amantle Montsho, having defeated her last week in Birmingham with a trademark late surge. But both finished behind the American Francena McCrory, with Ohuruogu unable to recover from a slow start and finishing fourth in 51.03.
The Olympic high jump bronze medallist Robbie Grabarz had returned to form in Birmingham last week with a season's best jump of 2.31m. But here he crashed out of the competition with three failures at 2.27m, finishing dead last in a high quality field in which the 23-year-old Ukrainian Bohdan Bondarenko, who finished seventh behind Grabarz in London, recorded the highest jump since 1994 to win with a leap of 2.41m to the delight of the crowd.
The Athletissima meeting at the atmospheric yet compact stadium in Lausanne, self-styled home of the Olympic movement, was attended by the IOC president, Jacques Rogge, and some of the 89 IOC members who earlier in the day voted to award the 2018 Youth Olympic Games to Buenos Aires, ahead of Medellín in Colombia and Glasgow. Glasgow's bid, which cost £2m, was eliminated in the first round of voting with just 13 votes of the 85 cast and Sir Chris Hoy, a bid ambassador, said he was "shocked and disappointed".
The week leading up to the annual Diamond League meeting had been a frenzy of lobbying and politicking in the city's finer hotels as the three potential hosts for the 2020 Olympics – Tokyo, Madrid and Istanbul – and the six candidates hoping to replace Rogge presented their cases to the IOC members before a vote in September.
