The Jamaicans are taking over that, too, from the Americans.

Brigitte Foster-Hylton captured the 100-meter hurdles title Wednesday, giving the island nation its first-ever gold in the event at the world championships. Delloreen Ennis-London also won the bronze for Jamaica.

"We're doing very good and we're happy," Ennis-London said.

The Americans, who've already lost two sprint races to Jamaica, were counting on gold.

Instead, they ran into obstacles. Ginnie Powell smashed a middle hurdle and finished sixth, while Olympic champion Dawn Harper clipped the second hurdle and took seventh.

Not exactly how they envisioned this playing out.

"I'm kind of ready to jump out of my skin," Harper said. "I'm trying to remain calm."

Powell knows the feeling.

"It's kind of sad, a letdown day," she said. "Two of America's best hurdlers couldn't medal."

That seems to be the case these days when the Jamaicans are involved. Then again, the country with a population of 2.8 million does boast the best runner on the planet.

Usain Bolt will try for his second world record Thursday in the final of the 200.

He obliterated his own world-record mark in the 100 on Sunday, blazing through the line in 9.58 seconds.

Shawn Crawford thinks he might have a way neutralize Bolt's burst _ trip him.

Of course the American was only kidding, right?

"The cameras make it hard to do that," Crawford said.

Bolt looked invulnerable in his semifinal heat of the 200, traipsing down the track in 20.08 seconds.

And that was in easy mode.

In the final, he'll crank it up to serious mode.

Bolt's world record in the 200 currently stands at 19.30, a barrier that Crawford fully expects him to break in the finals.

"I really think 19.28, that's what I think," Crawford said. "My goal is to run 19.51, I'll be happy with that."

That almost sounds like an admission of defeat.

But this is Bolt. And with his 23rd birthday on Friday, he might just give himself an early gift.

Still, he's already downplaying his chances.

"I have really not done the same amount of work like I did for the 100," Bolt said.

As he weaved his way out of interview area below the Olympic Stadium stands, Bolt carried his yam-colored Pumas in his hands.

His shoes were entitled to a little rest. He's been wearing them out by racing seven times in five days.

"I know Usain Bolt is an animal," said Wallace Spearmon, who finished the semifinals with the second-best time at 20.14 seconds. "I'm going to have to have the best race of my life to try to beat him in the finals."

Word that Crawford's predicting a time of 19.28 made Spearmon's eyes go wide in alarm.

"If they run (19.28) they can have it," Spearmon said. "I'm not going to say I can't run that fast, but that's pretty quick ... My best is 19.65 and I know it's going to take more than that to go out and compete with him."

That very well could be the case.

"He's just super human," said Jamaican teammate Steve Mullings, who's also in the final. "He's doing great. For him to be so good is actually a motivation for all the Jamaican sprinters. Looking at him run that fast makes you want to work more."
