Olympic trio to fine-tune in Monaco
Three of South Africa's Olympic athletes will turn out at the Diamond League meeting in Monaco on Friday as they sharpen their form ahead of the London Games.
The country's flag bearer at next week's opening ceremony, Olympic debutant Caster Semenya, lines up in the women's 800 metres race.
Semenya, a two-time IAAF World Championships medallist, is ranked outside the top 20 in the world this year, and she will be gunning for a morale-boosting victory.
Five women in the field have run faster than Semenya this season.
South Africa's only medallist at the 2008 Beijing Games, long jumper Khotso Mokoena, will look to gain a mental advantage over some of his likely challengers in London.
Mokoena is up against double World Championships medallist Mitchell Watt of Australia and European champion Sebastian Bayer of Germany.
Beijing Olympic champion Irving Saladino of Panama has been out of sorts this season and enters the competition as a dark horse.
Andre Olivier, 22, faces a strong field in the men's 800m race, including former world indoor champion Abubaker Kaki.
