Viljoen threw 64.92m on her first attempt and held the lead until Sara Kolak of Croatia over took her with a throw of 66.18m.
His fellow teammate, triathlete Henri Schoeman saw him claim the bronze medal in the men’s triathlon on the Copacabana course.
Meanwhile, Caster Semenya sailed through her 800m semi-final race Friday to cruise through to the finals.
Semenya comfortably won the race with a time of 1:58:15.
With Semenya producing lifetime best performances this year‚ many believe she can easily break the 1min 53.28sec world mark. The current Olympic record is 1:53:43.
Semenya ran the fastest time in the semi-finals, followed by Great Britain’s Lynsey Sharp (1:58:65) and USA’s Kate Grace (1:58:79).
Many observers insist Semenya will add another gold to South Africa’s haul of medals when she takes to the track on Sunday morning at 2.15am.
SA’s priority was to collect 10 medals, and as things stand with Caster on song, we could surpass the mark.
