Ian Poulter always believed he could shoot a low number in his final round after a 65 proved enough to give him victory at the WGC HSBC Champions in China.
The Englishman carded eight birdies and a solitary bogey on the Olazabal Course on Sunday to finish on 21-under, two shots clear of a four-man group containing Ernie Els and the American trio of Jason Dufner, Scott Piercy and Phil Mickelson.
The 36-year-old's charge was helped by the fact that overnight leaders Lee Westwood and Louis Oosthuizen both struggled on Sunday, the pair signing for even-par scores of 72 to finish on 18-under.
Oosthuizen had found himself five clear at the halfway stage after a second round of 63, only to then be joined at the summit on Saturday when Westwood fired a stunning 61.
"I said it in the press conference on Wednesday that I felt there was a 10-under-par out there on the golf course," Poulter said.
"We saw that in 11 and 12-under par (by Oosthuizen and Westwood), so I knew there was a good round of golf in me on that course.
"As we saw yesterday, if you start to go low and get a number on the board, you're going to be hard to beat.
"My short game has been good this week and at the 18th (where he made par from the greenside bunker) I knew I could get up and down from anywhere. And shooting 14 under over the weekend is a decent score."
Poulter has now won two WGC events in his career, a feat no other Englishman has achieved.
However, he insisted his latest triumph still didn't live up to the the thrill of helping Europe to glory in this year's Ryder Cup in Chicago.
"It still doesn't give you the kind of same buzz you get playing the Ryder Cup. There's just not quite as much adrenaline in the body," he admitted.
"I definitely think it is a part continuation of the Ryder Cup and I'm obviously riding that wave as much as I possibly can."
Rory McIlroy, who opted not to play in the tournament this week, was quick to congratulate his European team-mate.
"Ballsy up and down at the last," the current world number one wrote on Twitter. "Wouldn't expect anything less!"
