Peter Hanson put the biggest victory of his career down to his improved short game - and holding his nerve when it mattered.
The 35-year-old Swede made a series of clutch putts to hold off the charging Rory McIlroy and win the BMW Masters in Shanghai by a shot from the world No 1.
"Rory made a tremendous effort and put quite a bit of pressure on me - his second to the 15th was true class," Hanson said.
"He gave me a bit of a cushion early on (McIlroy missed two four-foot par putts) and I was maybe a little too defensive at the end, but it all worked out.
"My short game used to be my weak part, but I've been working on it and my putting has really improved."
McIlroy added: "I'm happy with how I played, but a little disappointed. I missed a few opportunities on the front nine and it was too little, too late.
"I wanted to make him work for it and it would have been nice to hole the putt on the last, but it wasn't to be and Peter deserved it."
Luke Donald was third ahead of another European Ryder Cup star, Ian Poulter in fourth.
"It just shows we had a strong team," Donald said. Poulter added: "The board is full of Ryder Cup players, which you would expect. The guys are still on a high - and rightly so."
Just a month after failing to win a point at the Ryder Cup - and being left on the sidelines for three of the five sessions - Hanson revealed that any hard feelings are a thing of the past.
In Chicago Hanson was angry to be left out all day Saturday and he said the following week that he might not be sending captain Olazabal "that many Christmas cards".
But the pair chatted last week and are back on good terms. "I was a bit disappointed," Hanson said, "but there's no feeling of revenge or wanting to show everyone now. It's a team effort and we ended up winning it."
McIlroy is staying in China, but only for a one-day head-to-head against Tiger Woods - joint fourth in Malaysia on Sunday after a closing 63.
The rest of the week is being spent with his tennis star girlfriend Caroline Wozniacki in Bulgaria - she is playing a tournament there - but he returns to Asia for the Singapore Open and his defence of the Hong Kong Open.
Those events will give the 23-year-old the opportunity to clinch the money list double before the race-ending World Tour Championship in Dubai on November 22-25.
