RANCHO MIRAGE, Calif. - Morgan Pressel never lost hope, even after she walked off the 18th green Sunday still three shots out of the lead with little reason to believe she would return an hour later for the greatest swim of her life.

Typical of her career, everything happened so quickly.

Pressel closed with a 3-under 69 at the Kraft Nabisco Championship, playing the final 24 holes without a bogey. Then she watched a series of collapses unfold on a sun-baked afternoon in the desert, none more shocking than Suzann Pettersen blowing a four-shot lead with four holes to play that made the 18-year-old Pressel the youngest major champion in LPGA Tour history.

About the only thing anyone could have predicted was Pressel in tears.

“Oh my God! Oh my God!” was all she could manage with a camera in her face when Pettersen’s 25-foot birdie putt to force a playoff stopped a few inches short.

These were tears of celebration as a major champion, not even a year after she finished high school. And she sobbed remembering her mother, Kathy, who died of breast cancer four years ago.

“I know my mother is always with me,” she said. “And I’m sure she’s proud of me.”

Pressel was at 3-under 285 and on the practice range when she entered the record books, winning a major at 18 years, 10 months and 9 days. Sandra Post of Canada won the 1968 LPGA Championship at 20 years, 19 days.

The youngest man to win a major was Young Tom Morris, who was 17 when he captured the 1868 British Open.

Pressel returned to the 18th not for a playoff she expected, but for a plunge into the pond with her caddie, Jon Yarbrough, and her grandmother, Evelyn Krickstein. Herb Krickstein, her grandfather and the father of former tennis player Aaron Krickstein, later dipped his toes in the water.

“This is a dream come true,” Pressel said.

Pettersen also shed tears, hers out of utter despair.

The 25-year-old from Norway seized control with three birdies in a four-hole stretch around the turn and had everything in hand until she started spraying tee shots under trees and into the ankle-deep rough, and could no longer make putts on the crusty greens.

A bogey on the 15th.

A double bogey on the 16th when it took her three shots to reach the front of the green and three shots with the putter.

A bogey on the 17th when her 7-iron came up short and she missed the par putt from 10 feet.

“I said yesterday that the one who made the fewest mistakes would win,” she said. “I did a few too many.”

She wasn’t alone.

Se Ri Pak had a chance to become the seventh woman to complete the career Grand Slam with a victory at Mission Hills, and she had a three-shot lead on the front nine. She couldn’t hold it together with bogeys on five of the last six holes, closing with a 77.

Catriona Matthew was at 3 under and standing over a 30-foot birdie putt when she ran it 5 feet past and wound up with a three-putt bogey that gave her a 71, finishing one shot back with Pettersen (74) and Brittany Lincicome (72).

Pressel was four shots behind when she finished Saturday afternoon. She was in the final group a year ago with Karrie Webb, who came from seven shots behind to win in a playoff.

“A little help never hurts,” Pressel said.

Was she ever right.
