Botswana won the race in Gaborone in 2:54.47. Its quartet included Olympic 200m gold medalist Letsile Tebogo and world 400m champion Collen Kebinatshipi.
The U.S., which did not contest the World Relays men’s 4x400m, registered the only faster times in history at the 1993 World Championships (world record 2:54.29) and the 2024 Olympics (2:54.43, where it beat Botswana by one tenth).
South Africa’s runner-up time on Sunday — 2:55.07 — marked the fifth-fastest relay in history. Pillay ran the fastest men’s 4x400m split in history of 42.66. American Michael Johnson had the previous fastest split of 42.94 from the 1993 Worlds.
