Defending champion Usain Bolt and world champion Yohan Blake moved safely through to tomorrow's Olympic 100-meter semifinals as American Ryan Bailey ran the fastest in today's heats.
Bolt, 25, in the fourth heat mouthed "No. 1, baby" to the capacity 80,000 crowd at London's Olympic Stadium, before easing through in 10.09 seconds. Blake, 22, clocked 10 seconds flat.
"My execution was good," Bolt, who set the world record of 9.58 seconds at the 2009 world championships, said. "I'm working on the last 50 meters. That's really my strong point."
