Cape Town - Sunette Viljoen and Khotso Mokoena will be taking part in their fourth Olympic Games in Rio next month after they were named in the 137-strong SA team on Thursday.
Viljoen, 32, finished fourth in the javelin at the 2012 London Olympics.
Mokoena, 31, meanwhile, won a silver medal at the Beijing Olympics in 2008, but finished eighth in London in the long jump.
