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.
