Sam Vines scored his first international goal on a header in the eighth minute, and a U.S. team mostly of backup players opened the CONCACAF Gold Cup with a 1-0 victory over Haiti on Sunday night.

Shaq Moore's cross bounced off two Haitans to Gyasi Zardes, who popped up the ball for Vines to head past goalkeeper Brian Sylvestre from 6 yards. Moore was making his sixth international appearance and Vines his fourth.

With the U.S. wearing new red-and-blue patterned road jerseys for the first time, Walker Zimmerman hit the crossbar just before Vines' goal and Nicholas Gioacchini struck a post in the 66th.
