Portugal lead U.S. 1-0 at halftime

MANAUS Brazil (Reuters) - Nani scored in the fifth minute to give Portugal a 1-0 lead against the United States at halftime in their Group G match on Sunday, firing home from the edge of the six-yard box after a defensive error by Geoff Cameron.

The winger nearly doubled Portugal's lead in the 45th minute when he struck the post with a long-range shot. U.S. goalkeeper Tim Howard made a fine save from Eder's follow-up effort.
