Australia's Brett Rumford produced an eagle on the first playoff hole to see off the challenge of Marcus Fraser and Peter Whiteford and win the Ballantine's Championship in South Korea.
All three men finished the tournament on 11-under-par before Rumford carved an iron to within five feet of the hole and rolled in an eagle three on the 18th.
Both compatriot Fraser and Whiteford of Scotland, who had chances to win the tournament in regulation play on the 18th, birdied the first extra hole but they were trumped by Rumford's eagle.
The victory is 35-year-old Rumford's fourth on the European Tour.
