His personal best in the 200 m is 19.65 seconds. This time (achieved in Daegu, Korea) made him the third fastest man over the distance at that point. He is currently ranked as the ninth fastest 200-meter runner ever. Only world record holder Usain Bolt (19.19), Yohan Blake (19.26), Michael Johnson (19.32), Noah Lyles (19.50), Walter Dix (19.53), Justin Gatlin (19.57), his training partner Tyson Gay (19.58), and Xavier Carter (19.63) have run faster. Despite the fact that he normally runs a "slower" first half of his 200 m races and goes on to pass people down the stretch, his 100 meters personal best is 9.96 s. He set that mark running in Shanghai on September 28, 2007, beating 100 m world champion Tyson Gay.
