Jeremy Wariner ran the third fastest-ever time to defend his 400 metres title in style at the World Championships in Osaka on Friday night.
After a conservative start, Wariner came off the final bend and powered down the home straight to win in 43.45seconds at Nagai stadium.
The 23-year-old Texan's devastating burst saw him lead LaShawn Merritt and Angelo Taylor to a clean sweep of the medals for Team USA.
Merritt was also rewarded with a lifetime best of 43.96secs, with Taylor clocking 44.32. Wariner's performance lies only behind fellow Americans Michael Johnson and Harry 'Butch' Reynolds on the world all-time list.
His latest display indicates he is capable of bettering the world record of 43.18 which his manager Johnson achieved winning the world title seven years ago in Seville.
