Noah Lyles set himself up perfectly for the Paris Olympics by haring to a personal best in winning the 100m at July 20 Diamond League meeting.
In the last sprint before theย Olympics, Lyles was quick out of his blocks and tore down the track at London Stadium to win in 9.81 seconds.
Once the American, who won the 100-200m golds at the Budapest world championships last year, got going, there was no doubt he would win.
South African Akani Simbine timed a seasonโs best of 9.85sec in second, while Botswanaโs Letsile Tebogo rounded out the podium in 9.88sec to match his own national record.
British champion Louie Hinchliffe, the winner of this seasonโs NCAA championships, was fourth in 9.97sec, while Zharnel Hughes had to be content with sixth (10.00) behind Jamaicaโs Ackeem Blake (9.97).
Hughes, who won bronze behind Lyles in Hungary, co-stars alongside the American in the Netflix docu-series โSprintโ, but said pre-race that he hadnโt realised how much his US rival talked about him.
Hughes had vowed to silence Lylesโ โloose mouthโ, but was never in contention as the American ripped away for victory in front of 58,000 fans at the stadium used for the 2012 Olympics and now home to Premier League club West Ham United.
