Jordan Ayew came off the bench to grab a hat-trick to lead Ghana to a comfortable 4-0 win over South Korea in their international friendly in Miami Gardens.
Ayew replaced injured forward Majeed Waris after just four minutes and opened the scoring with a deflected shot on the quarter-hour mark leaving South Korea's goalkeeper Jung Sung-ryong wrong-footed.
Ghana goalkeeper Fatau Dauda was called into action in the 40th minute as he palmed away a shot from Son Heung-Min to keep the African side ahead.
Asamoah Gyan made it 2-0 to the Africans when he dispossessed Kwak Taehwi near midfield, and dribbled 20 yards past Kim Young-Gwon to score from 15 yards in the 44th minute.
The Ghana substitute, Ayew, then added his second of the game in the 53rd minute as he struck a fierce long-range effort which nestled in the bottom corner to make it 3-0 to the Black Stars.
Kim Bo-kyung had the best chance of the game for South Korea but unfortunately he could not find the target and dragged his 67th minute shot wide from close-range.
Ayew then completed his treble in the last minute of normal time as he combined well with teammate Albert Adomah before slotting home from close-range to make it 4-0 to the Africans.
Ghana will now face the USA in their World Cup opener on Monday.
