NORTH PLAINS, Ore. — A shocking collapse by Annika Sorenstam gave way to the first three-way playoff in 16 years at the U.S. Women's Open.

Angela Stanford holed a 20-foot birdie putt on the 18th hole, Kelly Robbins birdied two of the last three holes and Hilary Lunke had to settle for par in a dramatic ending Sunday to a national championship that will go one more day.

They finished at 1-under 283 and will return Monday morning for 18 more holes.

Sorenstam won't be joining them.

The best player in women's golf was poised to win after a perfect drive on the par-5 18th hole, leaving her 236 yards away and making birdie seem like a done deal. Instead, she hit into the trees and into a bunker and finished with a bogey.

Sorenstam learned all about pressure two months ago at Colonial as the first woman in 58 years to play on the PGA Tour. It didn't pay off at Pumpkin Ridge.

She walked off the green stunned, yielding the stage to three players who will square off for the most prestigious prize in women's golf.

It will be the first playoff in the U.S. Women's Open since Se Ri Pak won at Blackwolf Run in 1998 and the first involving three women since Laura Davies defeated Ayako Okamoto and JoAnne Carner in 1987.

Lunke had a chance to win with the final putt, 15 feet below the cup for birdie. It had the right line but came up a foot short. She closed with a 75.

Robbins, a major champion who hasn't won in more than four years, went below par for the first time all week with a two-putt birdie on the 18th hole. She closed with a 69, one of only three players to break par in the final round.

The biggest surprise was Stanford, who started the final round one stroke behind Lunke and struggled to stay at even par over the closing holes. Her 20-foot putt curled down the ridge and disappeared into the cup, giving her a 74.

Still, this was Sorenstam's tournament to win.

She captured the LPGA Championship last month with two clutch shots to make par on the first playoff hole, and a large gallery crammed in around the 18th hole was waiting for the inevitable.

What they saw was a wild 4-wood that sliced into the trees, landing next to a fence surrounding the portable toilets. Sorenstam took nearly 20 minutes to get relief from the fence and the scoreboard, but her troubles were only starting.

From a dry patch of thin grass to a green running away from her toward a collection area, Sorenstam dumped her pitch into a bunker and blasted out to 15 feet. The par putt never had a chance, turning a few inches below the hole.

Sorenstam never birdied the 18th hole all week, but this was painful. She closed with a 73 and wasted an opportunity to win her sixth major and third U.S. Women's Open.

"I wanted to make birdie," she said. "Obviously, I played aggressive, it shot out to the right and the rest is history. I'm very disappointed, but I gave it my all."

Sorenstam finished at even-par 284.

Aree Song, one of 14 teenagers at the U.S. Women's Open, birdied the final hole for a 74 that left her alone in fifth at 285. The 17-year-old Song was low amateur, and automatically earned a trip back next year.

Michelle Wie shot a 76 with a new caddie. Her father, B.J. Wie, turned the bag over to his 13-year-old daughter's swing coach for the final round, and perhaps for a while.

"I fired myself," the father said with a laugh. "I caused too much trouble."

Wie's first U.S. Women's Open was marred by a controversy over etiquette, resulting in allegations that Danielle Ammaccapane bumped her — a claim B.J. Wie later retracted — and that the 16-year veteran berated the ninth-grader in the scoring tent.

Even if Ammaccapane apologized, Wie said she wouldn't accept.

That mess should fade by the time Robbins, Stanford and Lunke tee off at 9 a.m. Monday, one more round on a Witch Hollow course that required nothing but the best golf under the most excruciating pressure.

Robbins, who won the '95 LPGA Championship, figures to be the favorite, especially the way she played Sunday. Her approach into 2 feet for birdie on the 16th gave her a chance, and Robbins hit a 3-wood into 25 feet for eagle on the final hole.

For the first time, her hands were shaking. She backed off the putt, gave it a good roll but came up a few inches short and to the left.

"It's safe to say I was feeling it," she said. "And it was good to feel it again."

A victory Monday would give Robbins the largest comeback in U.S. Women's Open history. She started the final round six strokes behind.

The finishes by Stanford and Lunke were even more impressive considering their position.

Neither had contended in a major championship. Both watched Sorenstam hit great shots ahead of them and take a share of the lead. Then, they had to wait for what seemed like forever as Sorenstam got her ruling, took her drop and then fell apart.

Lunke, one of the shortest hitters in the field, barely cleared the hazard and went into a bunker, but her 107-yard shot gave her a shot at birdie and the victory.

Stanford hit a safe approach and pitched to 25 feet.

With Sorenstam out of the picture, Robbins watched from the scoring trailer, wondering if she would be the U.S. Women's Open champion or have to play Monday.

"Once Annika made her 6 it was, 'Well, now what?' Anything can happen," Robbins said.

Stanford lived up to that prediction.

One week after winning for the first time on the LPGA Tour, Stanford pumped her first once into the air, looking as stunned as those around her.

"I don't think I played well enough today to win, so I'm lucky to be playing tomorrow," Stanford said.

Lunke wasn't perfect either, making four bogeys in a five-hole stretch on the front nine to turn the U.S. Women's Open into a test of survival.

Lunke was three strokes ahead of Sorenstam as she walked up the 13 fairway, but two bogeys and a 25-foot par save by the Swede changed everything.

"When we watched Annika make that putt on the 14th, my husband turned to me and said, 'Game on,"' Lunke said.

Unlike Sorenstam, she was up to the task when it mattered.

U.S. Canadian PGA Championship: In Richmond Hill, Ontario, Tom Carter beat Jason Bohn in a playoff at the U.S. Canadian PGA Championship on Sunday for his first Nationwide Tour victory.

Carter rolled in a 15-foot putt for birdie on No. 18 to pull within one shot of Bohn, who bogeyed the final hole to force a playoff at DiamondBack Golf Club.

Carter fired a 1-under-par 70 in the final round, while Bohn, who started the day with a one-shot lead, had a 72 as both golfers tied with a 275 total.

They played No. 18 again and Carter parred it this time, missing his birdie putt by an inch.

Bohn sent a sand shot past the hole, hitting a cameraman before the ball ricocheted back to the front side. He got on to the green but missed his par putt, and Carter earned the winner's prize of $81,000. Bohn took home the second-place prize of $48,600.

"It all happened so quickly," Carter said. "I was keeping an eye on the leaderboard and my caddie told me that I needed to make birdie on 18 to get finished with a solo second. I was pretty pumped when I got in the playoff."

Bohn looked to be in good shape early Sunday with three birdies on his first 11 holes. He then bogeyed Nos. 12, 14, 17, and 18 to give Carter a shot.

"All I wanted to do was play it out of the bunker," Bohn said of the playoff hole. "I'm an aggressive player and I wanted to hit the pin and set myself up."

The win, his first in 68 starts, sent Carter from 54th to 10th on the money list with $115,756. He is in contention for a top-20 spot and a PGA Tour card for next season.

"I've been so close out here the past few years, so to finally do it is huge," Carter said. "Any time you win on any level, it is going to spur you to great things."

Blaine McCallister shot a 68 Sunday to finish third at 276 Derek Gillespie fired a 69 to finish tied for fourth at 277 with Jaxon Brigman, Steve Ford, Kelly Gibson and Scott Dunlap.

Gillespie would have been in even better shape, but spoiled a round that included six birdies with two bogeys and a double-bogey on No. 16.

"I got a little ahead of myself," Gillespie said. "I saw that my name was tied for fourth on the leaderboard and had a bad tee shot. I then doubled the hole."

EUROPEAN OPEN: In Straffan, Ireland, Phillip Price shot a 2-under-par 70 Sunday to win the European Open by one stroke.

Price almost blew the victory when he missed a 2-foot birdie putt on the 17th hole and settled for a bogey. But from the back of the green at the long 18th, he chipped down to 2 feet and made a birdie to win it.

Price finished at 16-under 272. Alastair Forsyth of Scotland and Mark McNulty of Zimbabwe shared second place after rounds of 68, and Gary Evans of England was fourth after a 68.

The Welshman, who beat Phil Mickelson during Europe's Ryder Cup victory last year, either led or tied for the lead after each round. It was his third win on the European Tour.
