Kaka appealed, arguing that the ball had crossed the line before Howard was able to get to it, and television replays appeared to show he was correct.

"I don't know whether the ball crossed the goal line," Kaka said. "Maybe the TV images will show. It would have been fantastic for me to score a legitimate headed goal."

Brazil has won eight matches in a row, and is unbeaten in 16. The five-time world champions also won the Confederations Cup in 1997 and 2005.

And in 15 matches against the United States, the Brazilians have only lost once - a 1-0 result in the 1998 CONCACAF Gold Cup.

The Americans reached the semifinals at the first World Cup in 1930, and made the quarterfinals in 2002. Besides that, its most famous victory before ending Spain's record 15-match winning streak in the semifinals was a 1-0 win over England at the 1950 World Cup in Brazil.

"I think people around the world see that we have a good team, we have good players," Bradley said. "Hopefully we can continue to step forward."

In the third-place match, Spain fought back to beat host South Africa 3-2 after extra time in Rustenburg.
