And this under the pressure of wanting to satisfy the aspirations of the many friends and family supporters from Pleasanton, the Californian town where she grew up and which is just an hour away from the Half Moon Bay's Ocean Course where the World Championship was being played.

"This really does mean a lot. I put so much pressure on myself every time I come here," said Creamer, who is famous for her fashionable golfing apparel and has been called the 'Pink Panther' because it is often comes in varying shades of pink.

"It's hard coming to your hometown. People watch you play all the time, but it's a different feeling when you're at home. You are constantly hearing, 'Go Pleasanton!'

"I wanted to win so badly, especially for all the people who have always supported me."

The 22-year-old Creamer beat Korean Song-Hee Kim by a stroke, closing with a bogey-free 3-under 69 for a 9-under 279 total.

She earned $250,000 for her 4th title of the year and eighth overall - a just reward for some super solid golf that saw her play the final 37 holes without a bogey.

The American young gun only need to hole a 5-foot par putt to win, but couldn't bare to watch as it rolled around the lip of the cup before dropping in.

"Honestly, I didn't see it go in. I had to wait to hear the people cheer," Creamer said. "It was like the longest two seconds of my life having it roll into the hole."

Kim, who closed with a 68 for her fifth top-five finish of the year, was signing autographs near the scoring tent when her coach told her to get ready for a possible play-off.

"I was hoping for that," she said, looking a little disappointed that it never happened

World No 1 Lorena Ochoa, the winner last week and the 2006 and 2007 winner here, shot a 69 to tie for third at 7 under with the multi-major-winning veteran Juli Inkster (68), the highly-ranked Norwegian Suzann Pettersen (68) and top-flight American Angela Stanford (70).

Creamer's victory on Sunday made her the first American to win at least four times in a single season since Inkster had five victories in 1999 and it is now six times out of 10 that Creamer has gone on to win after leading when heading into the final day.

"To play bogey-free on the weekend on this golf course and in these conditions, people don't realize how incredibly difficult that is," said Creamer's father, Paul. "But that's how she won."
