South Korean Song Young-han held his nerve to edge his role model, world number one Jordan Spieth, by a shot to win the Singapore Open in a weather-delayed Monday finish. Song returned to par the last three holes of his final round for a one-under 70 and 12-under total of 272, claiming the first title of his career after a number of second place finishes on the Japan, Korean and OneAsia Tours.

Double major winner Spieth, who also returned to the Sentosa Golf Club early to sink a five-foot birdie putt on the 18th, his only shot of the day, finished with a five-under 66. The duo were among 12 players forced to return on Monday after more stormy weather in the Southeast Asian city state brought an early end to Sunday’s play at the Japan Golf Tour and Asian Tour season opening event.

Speith, the 22-year-old Texan never truly hit his best form in Singapore this week and was guilty of missing a number of short putts on the large undulating greens that left him five back of Song after three rounds.
