World champions Australia warded off a spirited challenge from South Korea to carve a 4-2 victory and move to the top of the Sultan Azlan Shah Cup standings on Wednesday.
Leading by a goal, the Australian citadel came under heavy pressure from the determined South Koreans, but a 67th minute penalty corner goal from Mark Paterson on his second attempt sealed the issue in Australia's favour.
This was the second goal of the match for Paterson, who earlier scored a field goal in the 12th minute after Timothy Deavin opened the scoring for Australia in the eighth minute.
Seasoned striker Glenn Turner was the other goal scorer for the reigning World Cup, Champions Trophy and Commonwealth Games champions.
For South Korea, the two goals came through You Hyo-Sik (15th minute) and Hyun Hye-Sung (39th minute).
