third gold

Bolt claims third gold in 100m sprint

Bolt crossed the line in a season's best time of 9.81 seconds, with American Justin Gatlin just seven hundredths of a second slower to win silver yesterday.

Canada's Andre DeGrasse took the bronze.

The win takes Bolt a step closer to his goal of winning a historic triple-triple, which is the combination of winning gold in the 100m, 200m, and the 4X100m relay, in three consecutive Olympics.

The men's 200m sprint heats get under way on toda.
