Jordan Ayew scored three goals and Asamoah Gyan netted another on Monday in his return to the starting line-up as Ghana blanked South Korea 4-0 in a FIFA World Cup™ warm-up match.

Ayew opened the scoring in the 11th minute, followed with another goal in the 53rd minute and completed the hat-trick in the 89th minute.

Gyan, the former Sunderland striker, scored in the 44th minute. He had been among reserves earlier in Ghana's World Cup tune-ups but was among 10 players moved into the starting line-up for the Black Stars.

Ghana will open World Cup Group G play on 16 June against USA. The Black Stars knocked the Americans out of the World Cup in the Round of 16 in 2010 at South Africa and with a group-stage victory over them in 2006 at Germany.

Ghana will also face Germany in Portugal in other Group G matches at Brazil.

Korea Republic will try to bounce back from the drubbing in Brazil, with a Group H opener 17 June against Russia. The Koreans will also meet Algeria and Belgium in first-round matches.
