LANDOVER, Md. - Neymar converted a penalty kick and assisted on goals by defenders Thiago Silva and Marcelo as Brazil took advantage of a sloppy American back line to beat the United States, 4-1, in an exhibition game Wednesday night.
Neymar, the 20-year-old Santos sensation, put Brazil ahead in the 12th minute after a hand ball on Oguchi Onyewu, then took a corner kick that Thiago Silva headed in for his first international goal in the 26th.
Herculez Gomez, making his first start for the US since the 2010 World Cup, scored in the 45th following a fine run by Michael Bradley and cross by Fabian Johnson.
But before an enthusiastic crowd of 67,619 at FedEx Field, Marcelo restored the two-goal lead in the 52d as Onyewu and American captain Carlos Bocanegra left him unmarked in front.
Second-half sub Alexandre Pato added a goal in the 87th.
The 29th-ranked Americans, coming off a 5-1 win over Scotland last weekend, had difficulty coping with the pace of the five-time World Cup champions.
Coach Jurgen Klinsmann continued to tinker with his front line because Jozy Altidore didn’t arrive until Monday, and Clint Dempsey is recovering from a groin strain. Dempsey entered in the 57th minute, marking the first time he played with Landon Donovan since Klinsmann replaced Bob Bradley as coach last July.
Following a 1-4-1 start under Klinsmann, the Americans had won five in a row, including an impressive 1-0 victory at Italy. But the time for experimenting under the former German national team star and coach is nearing an end. The US plays at Canada Sunday, then opens qualifying for the 2014 World Cup June 8 against Antigua and Barbuda.
Brazil, which receives an automatic berth as the 2014 World Cup host, improved to 16-1 against the US with a 35-11 goal difference. The Selecao used a young roster as they prepare for the Olympics, which is limited to players under 23 plus three older players.
Neymar scored against the US in his national team debut two years ago. He took the penalty kick after the hand ball call on Leandro Damiao’s shot went off Onyewu, the tall defender who was benched after two games at the 2010 World Cup, but regained his form this season with Sporting Lisbon. American goalkeeper Tim Howard dived to his right but Neymar sent the ball the other way for his ninth international goal.
