Despite the agony of false-starting in the 100-metres final last Sunday, it was a very relaxed Usain Bolt who took his place in Saturday\'s final of the 200-metres in Daegu. There was nothing sluggish about Bolt\'s 200 metre display. Bolt surged in front and stayed there,taking the line in 19.40 seconds-his fourth-fastest 200 in history. Walter Dix of the United States won his second sprint silver in 19.70 and Frenchman Christophe Lemaitre earned bronze.
