Akani Simbine continued his phenomenal form in equaling the South African National Record to claim 100 metres glory in 9.97sec at the Summer Univerisade in Gwangju.
Simbine had broken the Championship Record in his semi-final with a swift 10.00 before shaving another three hundredths off his time in the final to comfortably beat Jamaica's Kemarly Brown and Turkey's Ramil Guliyev.
He also equalled a national mark set just four days ago by Henrico Bruintjies.
“I am very happy with the run," he said afterwards.
"I just kept focused and told myself to get though all my phases and when I get to the 60m I am going to power through.
“I just told myself to stay relaxed and get through the race, and I didn’t focus on the time much."
The performance also continued South Africa's brilliant recent sprinting record at the Summer Universiade after Anaso Jobodwana claimed 100m and 200m spoils at the 2013 edition in Kazan.
Kazakhstan's Viktoriya Zyabkina claimed the equivalent women's crown this time around, clocking 11.23 to beat Jamaica's Shimayra Williams and Russia's Elena Kozlova.
Russia also continued their good form in the distance events as Igor Maximov won the men's 10,000m in a time of 29:13.30.
Elsewhere today, Russia also claimed a superb mixed team diving title amid four gold medals in the sport for China.
France also enjoyed a successful day with two victories in shooting and one in fencing.
But hosts and medals table toppers South Korea remain the team to beat, claiming two taekwondo and one fencing titles to move onto 30 gold medals after eight of 13 days of action.
