Bolt and Blake destroy rivals for Jamaica double
Olympic champion cruises in the 200m as his younger compatriot runs third-fastest 100 ever
Olympic champion Usain Bolt ran 19.58 seconds for victory in the 200 metres at the Lausanne Diamond League meeting while Yohan Blake equalled the third fastest time ever to win the 100 metres in 9.69.
The effervescent Bolt performed the air guitar as he was presented to the crowd before dominating the race, winning ahead of Dutchman Churandy Martina as the top three all finished in under 20 seconds.
Other highlights of the meeting included another win for Grenada's teenage Olympic champion Kirani James in the 400 metres and the high jump where Qatar's Moutaz Essa Barshim leapt 2.39 metres to defeat Olympic champion Ivan Ukhov.
Less impressive was the 110 metres hurdles where Olympic champion Aries Merritt was disqualified for a false start.
Bolt, who has said his main aim was to see out the season without injury, seemed as pleased with his latest stunt as he was with his performance.
"It's fun, I heard the music and it just came to me, it was spontaneous," he said.
His fellow Jamaican Blake, Olympic silver medallist in the 100 and 200 metres, beat his previous best by 0.06 seconds as he destroyed a world-class field in the 100, leaving Tyson Gay and Nesta Carter trailing in his wake.
Blake's performance added to the feeling that the 22-year-old could be the one to eventually topple Bolt, who is four years his senior and beat him over both sprints at the London Games.
Merritt's disqualification devalued what was billed as one of the highlights of the evening in the hurdles.
His fellow American, London silver medallist Jason Richardson, took advantage as he led from the front to win in 13.08 seconds, ahead of David Oliver and Olympic bronze medallist Hansle Parchment, who was third.
James overcame a sluggish start to win the men's 400 metres, coming back strongly in the third 100 metres before powering clear down the final straight to win by several metres in 44.37 seconds.
Dominican Republic's Luguelin Santos was second in a repeat of the Olympic final. Barshim, 21, equalled the world's best performance this year in the high jump, with Ukhov and Britain's Robbie Grabarz on 2.37.
