London - Chad le Clos and Suzaan van Biljon both achieved milestones in the swimming pool in their respective semi-finals at the Olympic Games in London on Tuesday.
Le Clos secured his fourth final at the Games, becoming the first South African to do so since the country was re-admitted to the global showpiece in 1992.
He became an overnight international sensation after he unseated 15-time Olympic gold medallist Michael Phelps in the 200m butterfly final the night before.
Still reeling from Tuesday night's excitement, Le Clos advanced to the final of the men's 200m individual medley by the skin of his teeth.
Le Clos was up against four-time Olympic medallist Laszlo Cseh of Hungary in his heat as he touched sixth, recording a personal best time of 1:58.49.
His time was just good enough to secure a berth in Thursday's final with the eighth fastest time.
Van Biljon broke Penny Heyns' 13-year-old South African record of 2:23.64 in the women's 200m breaststroke semi-final.
She finished third in her semi-final with a time of 2:23.21 to advance to the final.

Captain Austin Smith made no mistake as he scored South Africa's first goal of the Olympics from the PC.
Jonty Robinson made it 2-1 a short while later to put SA in the lead for the first time in the fixture.

The South African rowing duo of Naydene Smith and Lee-Ann Persse put in a strong effort to finish second in the women's pairs B final on Wednesday.
