South African sprinter Wayde van Niekerk joined American great Michael Johnson in elite company while setting a national record in the 200 metres.
Van Niekerk clocked 19.94 seconds on Tuesday to become only the fourth runner to have a sub-20 time over 200 metres and a sub-44 in the 400.
He ran a career-best 43.96 this month to beat Olympic champion Kirani James of Grenada at the Diamond League meet in Paris.
Van Niekerk, who turned 23 on Wednesday, entered the 200-400 club alongside Johnson, LaShawn Merritt of the United States and Isaac Makwala of Botswana, according to the IAAF.
Makwala's African record of 43.72 set on July 5 retook the continental mark from Van Niekerk set one day earlier.
