CARLSBAD, Calif. -- Chad Campbell expected Tiger Woods to make that putt. No doubt about it.

“Didn’t ya’ll?” the talented Texan asked with a wry grin. “That’s the thing in match play. You have to expect him to make putts. I was getting ready to go to No. 1, to be honest with you.”

After all, the No. 1 player in the game was standing over a 12-footer on the 18th hole at La Costa Friday that would have sent his third-round match with Campbell into extra holes. And Woods’ legend has been built on making those kinds of pressure putts.

Only this time, his aim was off and Campbell had the hard-earned victory over Woods at the World Golf Championships-Accenture Match Play Championship. The 1-up win sent Campbell into Saturday’s quarterfinals against Tom Lehman, who was a 4-and-3 winner over defending champion David Toms.

The level-headed Campbell refused to get ahead of himself, though. Sure, he’d just beaten arguably the greatest player the game has ever seen, a player who thrives on the head-to-head challenge and who had already won the Accenture Match Play Championship twice.

“It’s pretty big, but the tournament is not over yet, just because you beat one guy,” said Campbell, who won the Bob Hope Chrysler Classic earlier this year. “I wish it was. I wish they gave the trophy away today, but they don’t.

“It’s definitely an accomplishment and I’m definitely proud of myself for grinding it out and playing so well under the pressure against the No. 1 player in the world. He definitely didn’t give me any holes.”

Campbell never trailed in his match with Woods, who would have shot 69 in stroke play with a birdie and an eagle -- but no bogeys -- on his scorecard. The 31-year-old Texan was nothing if not opportunistic, making four well-timed birdies in his first 10 holes to take a 3-up advantage.

“I was hitting good shots on the front nine and was able to make a lot of putts,” Campbell said. “He’s a guy you definitely want to get up on. You don’t want to be coming from behind. Even when you get up, you know he’s going to do something.

“The thing you don’t want to do against him -- or against anybody, really, but especially him -- is to make bogeys and kind of give him holes. I did that once on the back nine, and luckily it didn’t hurt me.”

Campbell lost No. 11 when Woods rolled in a 19-footer for birdie and the 12th when he couldn’t get up and down from the left side of the green at the par 3. But Campbell came right back with an 8-footer for birdie on the 13th hole to regain a 2-up edge.

“It’s tough to forget about them,” Campbell admitted. “Whenever you’ve got 3 up through 10, that’s a pretty good lead. And to give a couple of holes back -- standing on the 13 tee only being 1 up, you’re pretty disappointed. But too be able to hit a good iron shot off that tee and hit a solid 8-iron, that got me some confidence back.”
