Kim sat in the dining room at Sentosa Golf Club and munched on some late afternoon snacks while watching Green take a one-stroke lead to the 17th.
Kim finished with a 72-hole total of 17-under 271.
“Winning after such a long time, it feels like my first win of all,” Kim said.
“Ï made a really good putt on 16 to make birdie, but obviously pretty disappointed to have two 3-putts finishing,” said Green.
