Treble fever afflicts Van der Burgh

Veteran swimming star Cameron van der Burgh is eyeing a piece of history at the 2020 Tokyo Olympics, where he wants to become the first South African to win medals at three consecutive Games.Because the men's 100m breaststroke is on the first two days of the Olympics, Van der Burgh would potentially have the first crack at bagging a hat-trick of medals ahead of fellow swimmer Chad le Clos and 800m athlete Caster Semenya, also medallists at London 2012 and in Rio last month.
