Usain Bolt made light work of the opposition as he raced to the equal fastest 100metres time of the year at the IAAF Diamond League meeting in Lausanne on Thursday evening.
Bolt demolished the field as he matched the 9.82seconds fellow Jamaican Asafa Powell achieved at the Rome Diamond League meeting a month ago.
The world record holder, who withdrew from the 200m on the advice of a specialist who said racing a curve could further aggravate his sore hamstring, came through the race with no problems.
Bolt, running in perfect conditions, was fast out of the blocks and showed no signs of any physical problems as he raced clear of fellow countryman Yohan Blake, who posted a season's best of 9.96secs, with Churandy Martina third in 10.16s.
‘I'm so glad my wound didn't disturb me after having been absent for the last five weeks,’ said Bolt.
Lisa Dobriskey, following another late start to the season, proved her fitness with a solid performance in her first world class 1500m race of the summer.
Dobriskey clocked a season's best of 4minutes 1.83seconds to finish fourth as Ethiopia's Gelete Burka won a thrilling race, beating Morocco's Ibtissam Lakhouad by 0.07 in a world leading time of 3:59.28.
World silver medallist Dobriskey was quite happy to sit close to the back of the field until the closing stages of the race, setting herself up nicely as she moved into seventh position at the bell.
She gave it her best shot but failed to track down Kenya's Olympic champion and pre-race favourite Nancy Langat who finished third in 4:00.13.
Bershawn Jackson, the world leader in the 400m hurdles for the first time since 2006 following his victory at the recent USA Championships, won in 47.62 ahead of fellow American Angelo Taylor and the Dominican Republic's former world champion Felix Sanchez.
David Rudisha failed in his bid to smash Wilson Kipketer's 13-year-old world record of 1:42.61 in the 800m, finishing in a time of 1:43.25.
Ivan Ukhov won the high jump on countback ahead of fellow Russian Yaroslav Rybakov, both equalling the world's leading clearance this year of 2.33m.
