Summary
From the gun, Dai Tamesue was out fast, making up the stagger on Fabrizio Mori to his outside in lane 4 by the third hurdle. By the fifth hurdle, Félix Sánchez in lane 5 managed to catch Tamesue, with Hadi Soua'an Al-Somaily not too far behind in lane 1. Tamesue continued the pressure, regaining a slight lead on Sánchez, while Mori maintained the 1 metre gap while running a further distance around the turn. With long strides, Al-Somaily managed to virtually triple jump 13 strides into the eighth hurdle, seizing the lead from Tamesue. Both Tamesue and Al-Somaily began to struggle, their cadence was no longer what it had been. Sánchez maintained his cadence and cruised past, with Mori less than a metre behind. Mori challenged Sánchez to the line but couldn't get ahead. Three metres back, Tamesue was able to regain his advantage over Al-Somaily for bronze.
