Wayde van Niekerk is going faster and faster.
This time the South African track superstar bettered his personal best time in the 100m at an international athletics meeting in Velenje, Slovenia on Tuesday night.
Van Niekerk, the only man to have broken the 10-, 20- and 44-second barriers in the 100, 200 and 400m, won the men's 100m race in 9.94, slashing 0.04 off his previous best time set at his home base of Bloemfontein in 2016.
"I've very pleased," van Niekerk, who lowered his personal best in the 200m to 19.84 - a new South African record - ten days ago in Kingston, Jamaica, told the IAAF's website.
"It's my best time and I'm glad the competition ended the way I wanted it to. This also bodes well for my two main distances," Olympic 400m champion added.
His countrymen Emile Erasmus and Henricho Bruintjies finished second and third in 10.12 and 10.14 respectively, to complete a podium sweep for South Africa.
Isaac Makwala of Botswana dominated the men's 400m to win in 45.12, a full second clear of runner-up Mateo Ruzic of Croatia, who clocked 46.13.
In the women's events, South African Tamzin Thomas won the 200m in 23.82. Lydia Jele of Botswana was third in the women's 400m, after being edged out by the host country's Anita Horvat and Agata Zupin.
