Gyan fires Ghana past USA

Gyan ran onto a long ball from midfield, shrugged off two defenders and fired home a venomous shot that sees Ghana match the best previous performance by African teams at a World Cup.

The goal came after Ghana had been subjected to long periods of sustained American pressure with the teams having gone into extra time with the score tied at 1-1.

Ghana, who face Uruguay in the last eight on Friday at Soccer City in Johannesburg, are only the third African team to reach the quarters after Cameroon in 1990 and Senegal in 2002.

"I'm the happiest man in the world," said Gyan. "I'm pleased that Africa's happy that we qualified for the quarter-final. We have made Africa proud not Ghana alone but the whole of Africa."

U.S. coach Bob Bradley saw Ghana striker Gyan as the key difference on the night. "Gyan caused us trouble and got the winner," he said.

"Physically, he's a real handful and at the end of the day that's probably the area that too care of things. "At this moment it's a stinging, tough defeat... we knew Ghana was a good team yet tonight we didn't get the job done."

AMERICAN FIGHTBACK

The U.S. had fought back strongly after a sluggish first half, in which they fell behind to a fifth-minute goal from midfielder Kevin-Prince Boateng.

Landon Donovan, who had been the hero of their dramatic qualification for the knockout stage in midweek, equalised just after the hour mark from the penalty spot.

German-born Boateng, who qualified to play for Ghana on the eve of the finals, stole the ball from Ricardo Clark in midfield and ran on to fire home from the edge of the area in a perfect start for Africa's last representatives at this World Cup.

Ghana's teenage defender Jonathan Mensah gave away a 62nd minute penalty when he brought down Clint Dempsey.

Donovan struck his spot-kick in off the post to give the Americans a deserved equaliser as they suddenly found the energy to stage what has become a customary second-half rally.

Jozy Altidore might have snatched victory for the Americans 10 minutes from the end of normal time after getting the better of the Ghana defence, but hooked his shot wide.

After Gyan's goal, his third of the tournament, substitute Benny Feilhaber had a shot blocked in a goalmouth melee as the Americans attempted another comeback but it was not to be.

"We were a little naive tonight and at this level you cna't do that," said Donovan. "It is frustrating considering all the work we have put in, it just sucks man.

"I'm proud of what the team has done. Soccer is a cruel game sometime
