David Gillick finished in fourth place in the 400m at tonight's IAAF Golden League meeting in Zurich.
Gillick ran a time of 45.25secs to finish just outside the top three in a race that was won by world champion LaShawn Merritt in 44.21secs.
Derval O’Rourke ran a time of 12.97 to finish seventh in the women’s 100m hurdles, which was won by Bridgitte Foster-Hylton in a time of 12.46 secs.
Usain Bolt was staring a shock 100metre defeat in the face but powered clear to claim a dramatic victory, while Yelena Isinbayeva bounced back from her disastrous World Championship performance to set yet another pole vault world record.
Bolt looked like suffering his first 100m defeat since losing at the Stockholm Super Grand Prix in July last year only to recover to win in 9.81 seconds.
It was a close run thing for the Olympic and world 100m and 200m champion, who was the last to rise from his blocks and a metre down at the halfway point.
But just when all seemed lost, the world's fastest man changed gear 15m from the line to record his 11th successive 100m victory.
The 6ft 5in sprinter's lengthy final strides gave him victory ahead of fellow Jamaican Asafa Powell, who clocked 9.88secs, with American Darvis Patton third in 9.95secs.
‘I would say this was a shaky race, my body was sitting at the start,’ Bolt said afterwards.
The world record holder, who has undertaken a demanding social programme since winning the world title in Berlin, added: ‘I was a little bit tired through the race. But again it's all right.
‘All things considered the time was not bad. Yes, at the end I needed to pick up my speed as my body did not respond well to the race.’
Bolt, showing he still had some strength left, then returned to anchor Jamaica to victory in the 4x100m relay in 37.70s ahead of the USA (37.73), Trinidad and Tobago (38.20) and Great Britain (38.22sec).
Russian Isinbayeva, who failed to record a height in the final in the World Championship final in Berlin, could not have dreamed of a more polished return.
The 27-year-old banished any doubts her career may be in decline by raising her own world record by a centimetre to 5.06m.
Isinbayeva, who set her previous mark in winning Olympic gold in Beijing last year, opened with the bar at 4.71m and made a first-time clearance.
After clearing 4.81m and with the competition won, she then had it raised to to 5.06m.
The Russian, who had claimed she would never underestimate her opponents again as she did in Berlin, produced a perfect run up and made an easy clearance.
‘It's really unbelievable, crazy, amazing,’ Isinbayeva said after achieving her 15th outdoor record.
‘I felt fresh after Berlin when doing nothing there and I want to thank my fans for their support after that setback.'
