Wayde van Niekerk and Chad Le Clos have the potential to create history for South Africa at the Olympics next year - if they were to win at least two medals each. It would be the first time in 64 years that SA could have two multi-medallists at a single Games.The last time two members of a South African Olympic team made two visits to the podium at the same Games was at Helsinki 1952.Cyclists Raymond Robinson and Thomas Shardelow each won two medals that year, both in the now-defunct 2000m tandem - Robinson in the 1000m time trial and Shardelow in the 4000m team pursuit.Van Niekerk, who dipped below 20 seconds in the 200m in Switzerland on Tuesday night for his fourth national record in as many outings, could have as many as four podium opportunities - at least on paper.There is his favourite 400m, where he is the 11th-fastest yet, and then one, or more, of the 200m and the 4x100m and 4x400m relays.And if Van Niekerk were to achieve this feat in Brazil, he would be only the second SA track-and-field star to scoop two or more Olympic medals, the other being Bevil Rudd nearly a century ago.Rudd won gold in the 400m, silver in the 4x400m and bronze in the 800m at Antwerp in 1920.Rudd's winning time of 49.6sec was nearly six seconds slower than Van Niekerk's 43.96 national mark.Le Clos has already proved he can win multiple medals.He picked up two at the 2012 Olympics and the 2013 world championships, both in the 100m and 200m butterfly.And he heads into the world aquatics championships in Kazan, Russia, next month looking to increase his collection.The Durbanite arguably has the best turn in the world, which is a massive advantage in short-course competition, but now he will have to utilise more of his pure swimming skills.Le Clos failed to progress beyond the 50m fly heats in 2013, but his times have improved since then, although so far this year he is not even in the world top 20.He's also way down the list in the 200m freestyle, even below his teammate Myles Brown, who is 20th.But national coach Graham Hill is confident. "We're looking good at this stage."..
