Olympic champions Chad le Clos and Cameron van der Burgh will be ranked outside the world's top three going into the Rio Olympics next month. Rankings, schmankings! Fear not, South African fans - these two stars are all about racing, not ratings.The Americans made their mark on the world standings during their Olympic trials that ended at the weekend, although Michael Phelps failed to get a No1 placing for the first time since he was a 15-year-old preparing for his maiden Games at Sydney 2000.Le Clos is fourth in the 200m butterfly - the event in which he stunned Phelps to win gold four years ago - with his best time so far this year of 1min 54.42sec.Phelps, who clocked the world's best time last year, is behind him on 1:54.84.The man at the top is world champion Laszlo Cseh of Hungary on 1:52.91, the world's fastest time since 2009.But consider this: going into London 2012, Le Clos was ranked seventh and was 1.65sec behind Phelps's world-leading time; now Le Clos is 1.51sec behind the world leader.Le Clos is 12th in the 100m fly, where he is the world champion, but that's considerably higher than the 35th he was before London, where he won silver.Le Clos is 30th in the 200m freestyle, where he has been hoping to bid for a third individual medal.Van der Burgh is ninth in the 100m breaststroke, lower than his fifth spot four years ago, but on this occasion he was unable to race as frequently after his preparation was hit by a virus a month ago.Of the other South African swimmers, Christopher Reid is 11th in the 100m backstroke, his 53.12sec being one second behind the world lead held by American David Plummer.Myles Brown is 39th in the 400m freestyle and 49th in the 200m free; Jarred Crous is 41st in the 200m breaststroke (Van der Burgh is 24th in that event); Sebastien Rousseau is 21st and Michael Meyer 29th in the 400m individual medley; Matthew Meyer is 42nd in the 1500m freestyle, and Brad Tandy (33rd) and Doug Erasmus (53rd) in the 50m freestyle...
