Johannesburg - South African sprinting sensation Wayde van Niekerk improved on his own national mark at the Paris Diamond League meeting on Saturday.
Van Niekerk continued his rise in international track and field beating Olympic champion Kirani James of Grenada.
He won the men's 400m in 43.97 seconds to shave 0.28s off his previous best he
set in New York last month.
James had to be content with second place with his time of 44.17s.
Rounding off the podium, David Verburg of the United States clocked 44.81s for
third place.
The Free State athlete’s time is the second fastest this season, 0.02s slower
than James’ best this year.
South African javelin queen Sunette Viljoen, meanwhile, grabbed bronze with a best heave of 63.15m. Barbora Spotakova of the Czech Republic claimed first place with a throw of 64.42m while Australia's Kimberley Mickle took silver with 63.80m.
