South Africa's Louis Oosthuizen bounced back from last week's US Masters heartbreak by romping to a three-stroke win in the rain-hit Malaysian Open in Kuala Lumpur on Sunday.
Oosthuizen, who finished runner-up in the Masters to American Bubba Watson in a playoff, registered a total of 17-under 271, three ahead of Scotland's Stephen Gallacher.
The 2010 Open champion, who made a 30-hour journey from Augusta National to take part in the $2.5 million event in the Malaysian capital, fired a four-under 68 in the final round to win his fifth European Tour title.
The 29-year old Oosthuizen had to return to the Kuala Lumpur Golf & Country Club early on Sunday to complete the remaining eight holes of his third round after thunderstorms and rain had ended play early for the second consecutive day on Saturday.
Gallacher, 37, hit a bogeyfree round of two-under 70.
Rafael Cabrera-Bello of Spain, Danny Willet of England and Asian Tour rookie David Lipsky of the US shared the third spot, five shots behind Oosthuizen.
