Johannesburg - Olympic finalist Lehann Fourie set his season's best time in the men's 110 metre hurdles at the Lausanne Diamond League meeting on Thursday evening.
Fourie enjoyed an early lead in the hurdles event, setting a B-qualifying time of 13.43 seconds for the second time this season.
Fourie, who was a late addition to the entry list, finished sixth in the race, shaving 0.07 seconds off his previous best of the year.
David Oliver, of the US, finished first with a world-leading time of 13.03sec, with countrymen Jason Richardson second and Ryan Wilson third.
Andre Olivier, the only other South African at the meeting, withdrew from the men's 800m race because of illness.
Olivier's coach Jean Verster said he had picked up a fever overnight and was taken to hospital.
While he felt better after being placed on a drip and received antibiotics, he was unable to race.
