The United States have won the Olympic men's basketball gold by outgunning Spain 118-107 in the final.
Athens champions Argentina took bronze by outmuscling Lithuania in a 87-75 victory earlier on the final day of the Games.
World champions Spain were down by as many as 14 points in the first half but pulled to within two on a Rudy Fernandez three-pointer with 8:13 left in the match.
Jolted into action, Kobe Bryant swished two huge three-pointers, putting his finger to his lips after the second which put the US back up by eight with 3:10 left.
Dwyane Wade led the way with 27 points, sealing the game on another long bomb which he celebrated with a gunslinger's pose and a snarl of defiance to the crowd.
Bryant, who turned 30 the day before the final, added 20 points. The Americans, relegated to bronze in Athens four years ago, have now won 13 Olympic men's basketball titles.
The only cheer louder than that for Bryant's late three-pointer was when Chinese TV cameras spotted David Beckham courtside and his face flashed on the giant arena screen.
Crushed 119-82 by the Americans in the tournament's group stage, Spain hung tough in the final, Fernandez scoring 22 points and Bryant's Los Angeles Lakers team-mate Pau Gasol adding 21.
With an injured Manu Ginobili watching from the bench in jeans and a T-shirt, Carlos Delfino stepped up to lead 2004 gold medallists Argentina with 20 points against Lithuania.
Ginobili had been the tournament's leading scorer until he twisted his ankle in the first quarter of Argentina's semi-final loss to the United States.
"I wasn't able to run," the San Antonio Spurs guard said afterwards. "I didn't try to be a hero. I'm extremely proud of what these guys have done. It's kind of emotional."
