Yohan Blake, the world 100 metres champion and conqueror of training partner Usain Bolt at last month's Jamaican trials, warmed up for the London Olympics with victory in 9.85 seconds in Lucerne on Tuesday night - his third quickest time this summer.
In his final race before he joins up with his Jamaican teammates at their Birmingham training base, Blake made the most of a helpful tailwind of 1.6m/sec to race to a convincing win over compatriot Nester Carter, with Trinidadian Marc Burns third. Both men were timed at 10.00sec.
It was Blake's first competitive outing since his double triumph over Bolt in the 100m and 200m in Kingston and underlined again that he will be a powerful threat to his training partner's gold medal ambitions in London.
But Blake, 21, admitted that whatever the outcome, he will remain close friends with the triple Olympics champion, whom he credits with helping his development at the Kingston-based Racers Track Club.
"Win, lose or draw we are friends, even though it is business and he wants to win and I want to win," said Blake.
