Des Moines (USA): Christian Coleman believes his best is yet to come as he targets a 100m gold medal at this year’s World Championships in Doha. The sprinter, 23, underscored his status as the world’s fastest man on Friday after powering to victory at the US Track and Field Championships.

Coleman, who had earlier beaten world champion Justin Gatlin in the semi-finals with a time of 9.96sec, clocked 9.99sec into the wind to leave the field in his wake.
