Serbia beats US 11-6 to hand Americans 1st loss in men's Olympic water polo

LONDON - Vanja Udovicic scored three goals and Filip Filipovic chipped in with two more to give Serbia a 11-6 win over the United States in men's Olympic water polo.

It was the first loss of the London Games for the Americans.

Serbia scored the game's first three goals to take control and then opened up an 8-3 lead by doing the same to start the second half.

With the win, Serbia moved into first place in Group B with seven points and advanced to the quarterfinals. It can wrap up the group's top seed for the knockout stage by beating Romania in its last preliminary-round game on Monday.

The U.S., which has already secured a spot in the quarterfinals, is one point behind the Serbs, and plays three-time defending champion Hungary in its last group game.
