Usain Bolt can confidently move on to the 200m knowing he is the global sprint king after his stunning 100m victory at the World Championships when he shattered his own world record by a massive 0.11 seconds.
In an ecstatic Olympic Stadium on Sunday night, Bolt improved the world record by the biggest margin in history.
Perhaps more importantly, the Jamaican has also turned the normally placid world of athletics upside down with his humour and light-hearted approach, including his admittance to his pre-race munching of chicken nuggets.
His prancing around before starter's orders, including the trademark stance of aiming his invisible bow and arrow towards the sky, has delighted the crowd.
Taking just 33 steps to hurtle his towering 6ft 5in frame down the track, Bolt destroyed a high-class field in running 9.58, bettering the previous best he set exactly one year previously in the Beijing Olympics final.
And the 22-year-old promised there was a lot more to come.
"I said I could run 9.4. I think it will stop at 9.4 but you never know," said the Jamaican.
Running 9.5 is definitely a big thing. I'm proud of myself because I'm the first man to have done that."
American defending champion Tyson Gay finished second in a time of 9.71, a new national record but seemingly trivial in comparison to Bolt's feat. Jamaica's Asafa Powell claimed bronze in 9.84.
Questioned whether he is the best-ever sprinter, Bolt was modest: "I don't know. I'll have to let the people, the fans, decide."
Heats for the 200m (with the participation of Malta's Nikolai Portelli) are scheduled for today, with the semi-final tomorrow and final on Thursday. The 4x100m relay heats are on Friday with the final on Saturday.
Bolt acknowledged that his world record over the 200m of 19.30 would not likely be in jeopardy.
"I doubt I'm going to get the world record in the 200," he said.
"I'm going out there to run hard, definitely, but I think it is going to be even more difficult."
Gay injured
Tyson Gay has withdrawn from the World Championship 200 metres because of a persistent groin injury, his agent told Reuters last night.
The American, the 200 world champion, will not defend his title but does still hope to run in the 4x100 relay.
"The groin is too sore," his agent Mark Wetmore said.
