Usain Bolt at the Olympics

LONDON -- Usain Bolt took a day off and let his teammates do the work. They gave Bolt a chance for another triple sweep.

The World's Fastest Man returns to Olympic Stadium on Saturday for the men's 4x100-meter relay final and his shot at taking home three gold medals in as many sprinting events at the London Games.

"We've got guys that have been running good and we've got Usain Bolt, who's going to run a fast time," Jamaican teammate Yohan Blake said. "It's going to be interesting."

Sure is, especially after the Americans ran the fourth-fastest time in history in their semifinal Friday night.

That allowed them to believe anything's possible – maybe even a win over Bolt.

With Justin Gatlin running the anchor leg, the U.S. broke a 20-year-old national record in its heat, finishing in 37.38 seconds. The old record, set in 1992 with Carl Lewis as the anchor, was 37.40.

Jamaica, running in the evening's opening heat, was only a hundredth of a second slower than the United States – and that was with Bolt on the sideline.

"We're going to figure out a way to go out there and compete with them," Gatlin said. "We're not scared of them."

In the final, Bolt will take Kemar Bailey-Cole's place on the anchor leg. Nesta Carter, Michael Frater and Blake, the 100- and 200-meter runner-up, will run in the first three spots, just like they did in the preliminaries.
