Charl Schwartzel ended his 20-month win drought in emphatic style with a 11-shot victory at the Thailand Golf Championship.
The South African, who had held the lead from day one, completed his pillar-to-post success at Amata Spring with a third 65 of the week to post a winning total of 25-under.
Starting the day five shots clear, Schwartzel had six threes on his card as he turned in four-under 32 and he added three more on the back nine to complete the romp and claim his first title since his 2011 Masters win at Augusta.
Current Masters champion Bubba Watson came through the field on Sunday with a seven-under 65 that saw him take a share of second place with home hero Thitiphun Chuayprakong (70) on 14-under.
Sergio Garcia raised hopes of a final-round charge with two birdies in his first three holes but the Spaniard couldn't make further progress and finished alone in fourth after a closing 70.
England's Simon Dyson climbed to sixth after finishing with a 68 while defending champion Lee Westwood had to settle for tied 11th after his third two-under 70 of the week.
A delighted Schwartzel said: "It's been a while and I have been knocking on the door for quite some time.
"Winning is not as easy as everyone thinks it is," added the South African, who said he'd played plenty of good golf over the last 20 months without getting the reward of a victory.
"It's nice to finish the year with a nice win here and play some decent golf," said Schwartzel, who had just one bogey on his card all week.
