10. Geoff Ogilvy beats David Howell on 19th hole
Year: 2006
Course: La Costa Resort and Spa, Carlsbad, Calif.

This quarterfinal victory was Ogilvy's fourth consecutive match to go to extra holes. He went on to win the championship, placing him in the marquee player category, especially after he went onto win that year's U.S. Open.

9. Scott Verplank beats Lee Westwood on 26th hole
Year: 2006
Course: La Costa Resort and Spa, Carlsbad, Calif.

This first-round match was the longest match in tournament history. The win may have spent Verplank, who went on to finish T17. He finished the 2006 season with two runner-up and nine top-25 finishes.

8. David Toms beats Chris DiMarco, 6 and 5
Year: 2005
Course: La Costa Resort and Spa, Carlsbad, Calif.
Video highlight
Toms won by the largest championship-match margin in tournament history. It brought Toms' AMPC career record at that time to 18-5 in six starts, second only to Tiger Woods. The margin actually could have been bigger. Toms took a 6-up lead after 18 and was 9-up at one point. It wasn't all bad for DiMarco. Later that year, he went on to becoming the hero of the U.S. team's victory in the 2005 Presidents Cup.

7. Nick O'Hern beats Tiger Woods, 3 and 1
Year: 2005
Course: La Costa Resort and Spa, Carlsbad, Calif.
Video highlight
O'Hern was No. 31 seed. He would go on to beat Luke Donald, 5 and 4 before losing to Ian Poulter, 3 and 1 in the quarterfinals. That would not be the only luck O'Hern would have against Woods, either. He ended Woods' seven-tournament winning streak by beating him in a 20-hole thriller in the third round of last year's event.

6. Kevin Sutherland wins title
Year: 2002
Course: La Costa Resort and Spa, Carlsbad, Calif.
Video highlight
Sutherland, the No. 62 seed, posted six upsets to win championship for his first and only PGA TOUR victory. To win the title, he beat Scott McCarron, 1up in the 36-hole final with an up and down from the bunker on the final hole.As if that weren't enough, he beat David Duval in 20 holes in the opening round, Paul McGinley, 2 and 1 in round 2, Jim Furyk, 4 and 3 in the third round, David Toms, 3 and 2 in the quarterfinals and Brad Faxon, 1-up in the semis.

5. Peter O'Malley beats Tiger Woods, 2 and 1
Year: 2002
Course: La Costa Resort and Spa, Carlsbad, Calif.
Video highlight
O'Malley, a No. 64 seed beat Woods, the top seed, in the first round. Woods had come off the 2001 season, where he was named Player of the Year and won five times, including both THE PLAYERS and the Masters. The glory did not last, as O'Malley lost in second round to Nick Price.

4. Darren Clarke beats Tiger Woods, 4 and 3
Year: 2000
Course: La Costa Resort and Spa, Carlsbad, Calif.
Video highlight
The win made Clark the first European to win a World Golf Championships event. Three of the four top-seeded players were in the semifinals, the most top-seeded players to date. Clarke beat David Duval in his semifinal match. The win deprived Woods of capturing his first ACMPC (he had already won the Bridgestone twice, the CA once and the World Cup with Duval.

3. Jeff Maggert chips in on 38th hole of championship match to beat Andrew Magee

1. Tiger Woods beats Stephen Ames, 9 and 8
Year: 2006
Course: La Costa Resort and Spa, Carlsbad, Calif.
Video highlight
Ames had been asked earlier in the week what his chances were against the world's top-ranked player. "Anything can happen....Especially where he's hitting the ball," Ames said. Woods apparently took his comments seriously. As he climbed into a van behind the 10th green after halving the hole with pars, he was asked he had seen what Ames said. "Yes." Did it motivate him? "Yes." Asked if he cared to elaborate, Woods smiled, "No." Woods finished T9 in the event. Both players went on to have stellar seasons. Ames went onto win THE PLAYERS; Tiger went on to finish the season with eight victories including the British Open, PGA Championship and the other two WGC events, claiming yet another Player of the Year honor.
