Sergio Garcia shot a stunning closing 61 to claim the rain-shortened Johor Open in Malaysia.
It was the 32-year-old's second win of 2012, after he claimed the Wyndham Championship on the PGA Tour in August.
The Spaniard took full advantage of the event being cut to 54 holes after severe storms and eventually finished three shots clear on 18-under-par.
His final round included seven birdies on the front nine to go out in 32, before adding a further four - after a long rain delay - on the back nine.
American Jonathan Moore also shot a 61 to finish second, with Thailand's Thongchai Jaidee third on 14-under-par.
Garcia's final round was the lowest ever by an Asian Tour winner, he said: ""It has been a long week obviously because of the weather and I couldn't have asked for a better way to end the week."
The world number 20 continued: "It has been a great experience as this is my first time in Malaysia and to be able to win is a treat. The most important thing about playing under these kinds of conditions is to keep the momentum going, especially with so much disruption. It's hard to keep up mentally and I sort of did that yesterday morning where I finished poorly, but today I came back strongly."
Garcia's win aso marks the first on tour for the new RocketBladez Tour irons.
