Ockie Strydom shot a stunning nine-under round of 63 to seal victory in the Singapore Classic by one stroke on Sunday.

The South African's final round was the best score of the day at the Laguna National Golf Resort Club and propelled him to top spot ahead of Sami Valimaki of Finland.

The victory is Strydom's second on the DP World Tour after he claimed the Alfred Dunhill Championship on home soil in December.

"It's my mindset that's changing at the moment," he said. "When you've been in that situation before you know you can do it again.

"I was thinking of not being here this week as I was hitting it so badly. My coach and wife said 'maybe it's your week' and look what happened, it was my week!"

Joint leaders after the third round, Wang Jeung-hun and Alejandro del Rey, finished in a tie for third with Marcel Schneider, four shots back from Strydom.
