Tuks teammates Akani Simbine and Henricho Bruintjies share a house in Pretoria - and now they share the South African 100m record. Simbine bagged SA's first medal of the World Student Games in Gwangju, South Korea, yesterday as he clocked 9.97 seconds to equal Bruintjies's four-day-old mark. That time also goes down as a record for the university showpiece.Jamaica's Ashani Brown was second behind Simbine in 10.12 and Ramil Guliyev of Turkey finished third in 10.16. Simbine's win also meant that the 100m title stayed in South Africans' hands, having previously been taken by Anaso Jobodwana at the 2013 edition in Kazan, Russia.Jobodwana, who has since turned professional, won the 100m and 200m double two years ago.Ncincilili Titi - who like Jobodwana is based in the US although they come from Eastern Cape - makes his bid for 200m glory today.He was the fastest of the second round on Thursday, going 20.84.Simbine said he had focused on the victory, not the time."I'm very happy with the run. I just kept focus and told myself to just get through all my phases and when I get to the 60m I know I'm going to power through," said University of Pretoria student Simbine, who broke 10 seconds for the first time earlier this month when he achieved 9.99sec in Slovenia.The triumph will be a confidence-booster ahead of the world championships in Beijing next month, although it should be remembered that World Student Games champions have seldom excelled on the biggest stage of all.Bruintjies, who went 9.97 in Switzerland on Sunday to beat Simon Magakwe's 9.98 milestone from last year, and Simbine have spoken frequently about the potential of a South African 4x100m relay team.Jobodwana fended off his more fancied rivals in Switzerland last night but he was still beaten into second place by British upstart Zharnel Hughes.Hughes won this Diamond League race in a 20.13sec personal best, comfortably in front of the South African speedster in 20.21.Jobodwana was well short of his 20.04 national record, but his placing pushed him to the top of the 200m Diamond Race with six points...
