Usain Bolt and Justin Gatlin moved closer to setting up the biggest duel of the world track and field championships, striding into the semifinals of the 100 meters with victories in their heats on Saturday in Beijing.

Gatlin upstaged the Jamaican with the top time in the first round, even though the American got a little push from nature with a strong back wind of 2.1 meters per second during his 9.83-second race. Bolt faced a slight headwind as he cruised to a time of 9.96, the fifth fastest overall.

"It was OK. It was not perfect," Bolt said.
