CARLSBAD, Calif. - The final eight golfers left in the Match Play Championship include three Australians and just two of the top 10 seeds.

Vijay Singh, Tiger Woods and Phil Mickelson are not among them. The top three seeds were sent home Friday from La Costa, which proved to be wild as well as still wet.

"That's the beauty of this tournament," David Toms said after eliminating Mickelson in the third round to advance to Saturday's quarterfinals. "Phil and I were talking today, when he shot that low round at Spyglass (62), you get a big lead on the field. Here, you can do that in one match. And the next match, if you don't play, well, you're gone."

The highest seed remaining was U.S. Open champion Retief Goosen (No. 4), who rallied from 3 down with eight holes to play and beat hard-luck Chad Campbell on the 19th hole.

Campbell played more holes Friday (43) than he did all week at the Nissan Open, where he lost a one-hole playoff to Adam Scott in a tournament shortened to 36 holes by rain.

Scott is one of three Aussies in the quarterfinals; the others are Nick O'Hern and Robert Allenby.

"It doesn't matter who you play. Anyone in this field can win," Allenby said after beating Kirk Triplett.

For Singh, the world's top-ranked golfer, it was nothing new. He has never advanced to the third round, a streak that was kept intact when Jay Haas beat him 3 and 2.

Woods lost for the first time in 13 matches, his two-year reign ended by little-known O'Hern.

O'Hern hasn't played in this event since he got in as the 39th alternate four years ago in Australia, the year none of the stars showed up. He lost then to eventual champion Steve Stricker in the quarterfinals.

"That was a tough loss to take," O'Hern said. "I always wanted to get back to this tournament."

O'Hern hit most of the fairways, made all of his important putts and never trailed in a 3-and-1 victory, ending the match with a 3-iron from 200 yards out of the rough to 25 feet and holing the putt.

"If I play solidly, I have a good chance of beating anyone," O'Hern said. "Tiger missed a few putts, which helped me out. But that's golf. You take your chances."

The lefty made a 10-foot birdie putt on the second hole, and when Woods missed a 3-foot putt on the next hole, the Aussie went 2-up.

"I didn't make the putts," Woods said. "That's the difference between winning and losing a match."

It was the first time Woods lost in the Match Play Championship since another unheralded Aussie, Peter O'Malley, knocked him out in the first round three years ago.

After beating Woods, O'Hern birdied his first two holes of his third-round match and easily beat Luke Donald of England, 5 and 4, to reach the quarterfinals against Ian Poulter of England.

Mickelson was coming off two straight PGA Tour victories and never trailed in his first two matches, making four straight birdies early on to beat Angel Cabrera in the second round.

Toms couldn't keep up with Lefty off the tee, but he kept it in the fairways and made enough medium-length birdie putts to make Mickelson press, only to fall further behind. The match ended on the 16th hole.

In other third-round matches:

- Chris DiMarco beat John Daly in the morning, then never trailed against Haas to win, 2 and 1. DiMarco has played only his fellow Americans the first three rounds and gets another one Saturday morning in the quarterfinals. That would be eighth-seeded Stewart Cink, who birdied the 18th hole and beat Davis Love III on the 20th hole.

- Goosen outlasted Fred Couples in the morning, then rallied to beat Campbell with a 4-foot birdie on the 19th hole. Next up is Allenby.

- Scott beat David Howell of England, then overwhelmed Sergio Garcia in a match of the best two players younger than 25. Scott won three straight holes to end the front nine, then never gave the Spaniard a chance in winning, 4 and 3. He faces Toms in the quarterfinals.

- Poulter kept a European presence at La Costa. The Englishman won three of the last five holes and defeated Rory Sabbatini, 1 up, to reach the quarterfinals for the second straight year. He faces O'Hern.
