Joaquín Niemann of Chile won the LIV Golf Singapore by five strokes Sunday, securing his second victory in four events this season.
The 26-year-old Niemann made six birdies in his final round of 6-under 65 for a total of 17-under at the Sentosa Golf Club.
"Today was one of those days," said Niemann, who also won the LIV event last month in Adelaide, Australia. "Everything went my way."
American Brooks Koepka finished second at 12-under, with Ben Campbell in third at 11-under.
"Not really hitting it great," said Koepka, who also shot a 65 on Sunday.
