Jamaica are through to the final of the Gold Cup after a 2-1 victory against the United States at the Georgia Dome.

The Jamaicans took the lead just after the half-hour mark when Darren Mattocks met a cross from Jobi McAnuff before guiding an effort beyond Brad Guzan.

Former Derby County star Giles Barnes extended Jamaica's advantage when he curled home a free kick four minutes after Mattocks's opener.

The United States were back in it three minutes into the second period when Michael Bradley reacted quickest to tap home after Ryan Thompson failed to hold a shot from Aron Johannsson.

Johannsson should have restored parity minutes later but he could only head over the bar from close range.

Bradley's long-range effort hit the goalkeeper before bouncing onto the post before the hour mark, as the USA again failed to claw their way back.
