England's Steve Webster won the Portugal Masters with the European Tour's best winning final round of the season, a 64 in Vilamoura.
One behind Daniel Vancsik overnight, Webster went to the turn in four under, then sank an eagle putt on the 12th.
Swede Robert Karlsson was two shots behind, Vancsik finished third and Lee Westwood joint fourth.
Webster's only previous European Tour victory in over a decade as a pro was the Italian Open two years ago.
He claimed the first prize of nearly £350,000 with a 25-under-par total that was the lowest of the season then, remembering the death of his mother earlier this year, collapsed in tears.
I was thinking about my mum all the time and it was so hard to keep my mind on the golf
After being congratulated by his father Terry, Webster said his victory was an emotion-packed affair.
"I lost my mum in the early part of the season and it really knocked me about," he told reporters. "I didn't think I'd even keep my card because it was tough.
"But I had a great result at Loch Lomond (Scottish Open in July) and that seemed to help me turn the corner, I became more positive.
"It was so hard out there, especially coming down the stretch, because I was thinking about my mum all the time and it was so hard to keep my mind on the golf. But I knew she was
looking down on me."
Meanwhile, Justin Rose's 21st place was not good enough for him to overtake Irishman Padraig Harrington in second place on Europe's money-list.
With top man Ernie Els not playing in the season-closing Volvo Masters the week after next, that event could see a straight fight between the two for the order of merit.
"I'm looking forward to going to Valderrama now because I prefer it when courses are tougher," Rose said.
"My goal is to win the Volvo Masters and then I'll win the
order of merit, so it's a double-whammy.
