After two years of showing promise, Jobodwana produced a breakthrough performance in the Cayman Islands on Saturday evening, smashing the South African 200m record.
The 22-year-old US-based sprinter won the half-lap event at the Cayman Invitational in 20.06 seconds, with 19-year-old Zharnel Hughes of Anguila taking second place in 20.15.
Jobodwana improved the national mark of 20.11 set by Morne Nagel in Germiston in April 2002.
“It felt good, especially when I saw the time flash on the electronic timer,” he said.
Aiming to build on his spectacular early-season form, Jobodwana said he would race again at the Diamond League meeting in Eugene, Oregon, in two weeks’ time.
Meanwhile, 23-year-old Smith, also based in America, broke her own national mark by 61 centimetres with a 60.99m effort at the Big 10 Championships in Michigan.
