博尔特夺百米冠军 苏炳添进百米决赛

Jamaica's Usain Bolt put all doubts to rest after producing his biggest clutch performance to beat rival Justin Gatlin in the 100-meter final.

Bolt clawed back into contention after trailing for most of the race and made his giant stride count to win in 9.79 seconds - .01 seconds faster than Gatlin.

The two-time Olympic champ says he needed to take the pressure off himself for the finals after his sub-par semi-finals finish.

"I remember I come around and my coach asked me what happened, and I said I really don't know and he said, I think you think about the race too much, you think about try to get a perfect race, get anything better, and he said listen, you've been here too many times and you know what takes you to win, so just relax and get it done and execute it, and all you can do is just to execute as possible as you can."

For his part, Gatlin says, despite taking silver, he gave it his all:

"At the end of the day, I had a good stretch, I showed a lot of competitiveness, I went out and then gave it, all I can give at this point of time. The last five metres was little crucial, lean forward a little bit too much and caught off a little unbalanced, but it was a good race and all."

At 33, Gatlin had been unbeaten for two years as Bolt struggled with injury. But on the biggest of occasions, timing was with Bolt again.

In a dead heat for third, Trayvon Bromell of the United States and Andre De Grasse of Canada shared bronze in 9.91 seconds.

Chinese sprinter Su Bingtian became the first from his country to run the blue-ribbon sprint event final at the outdoor world championships.

Finishing ninth in 10.06 in the final, Su says it is a huge encouragement for him and he is confident that he can run faster in the future.

"I think maybe I didn't have sufficient energy for the final. But I am satisfied with my result. It was my third fastest result. "

Su was able to stand at the start line after a dramatic semifinal in which he was among three athletes who all clocked 9.99 seconds and all of them qualified to make it a rare nine-man final.

It is also the first time in world championships history that a sub-10 seconds time has been required to reach the final.
