Cape Town - Caster Semenya silenced her critics, storming to gold in the women's 800m final at the Rio Olympics.
Semenya celebrated with her trademark 'cobra' pose and then did a little dance as she won Team SA's 10th medal at the Olympic Stadium.
Semenya finished in 1:55.28 - her new personal best as well as a new national record.
Burundi's Francine Niyonsaba was second in 1:56.49 while Kenya's Margaret Wambui claimed bronze in 1:57.52.
Semenya has been at the centre of a debate surrounding testosterone levels in female athletes after a Court of Arbitration for Sport (CAS) decision taken in July 2015 put a stop to testosterone regulation in female athletes.
For now at least, the 25-year-old SA track star has silenced her critics.
Gold Gold Gold for Caster ???????????????????????????? proudly South African. @caster800m was never a doubt
