Clint Dempsey and Oguchi Onyewu scored on second-half headers to spark the United States past China 4-1 in San Jose, California, Saturday in a football friendly that served as a tournament tuneup for both.

The Americans, who improved to 5-1 overall against China, rose to 4-0 with one drawn this year and stretched their scoring margin to 12-3. They open defense of their North American crown next week in the Gold Cup.

China slid to 2-3 in 2007 ahead of next month's Asian Cup, pressure growing after losing last month to Thailand for the first time in 14 years. China will open Asian Cup play in Group C with co-host Malaysia, Iran and Uzbekistan.

US midfielder Benny Feilhaber, who plays for Germany's Hamburger SV, scored his first international goal in the 28th minute, chipping over goalkeeper Chen Dong off a pass from debutante Sacha Kljestan to give the Americans a 2-1 lead.

China's Shao Jiayi had the best chance to equalize but blasted the ball into the left side of the net in the 72nd minute.

Chen denied Clint Dempsey on a breakaway in the 64th minute and dived left to make an outstretched grab to thwart Beasley in the 73rd minute, but the Americans would not be denied.

Feilhaber sent a corner kick into the area that Dempsey, the only American goal scorer in last year's World Cup, nodded home in the 75th minute to give the US squad a 3-1 edge.

US defender Oguchi Onyewu of Standard de Liege nodded home a free kick from US veteran DaMarcus Beasley in the 78th minute for his second international goal to seal a US triumph.
