HERTFORDSHIRE, England -- Adam Scott was in the media center, talking about the daunting task of trying to overtake Tiger Woods on Sunday during the final round of the World Golf Championships-American Express Championship.

Meanwhile, the game’s No. 1 player was on the golf course, making sure the Aussie had even more of a challenge. Within minutes of the end of Scott’s interview, Woods had rolled in a 34-foot eagle putt on the 18th hole that opened up a six-stroke advantage.

The eagle was the third straight for Woods at the 18th hole, and it added an exclamation point to a day when the defending champion had seemed almost -- dare we say it? -- human. The 67 left Woods at 19 under as he seeks his sixth straight PGA TOUR win.

Scott, who is alone in second, had said he felt he needed to be within four shots to have a chance to overtake Woods -- and he was until that closing eagle. The game’s No. 1 player is the consummate frontrunner, winning 37 of 40 events when he’s owned at least a share of the 54-hole lead.

“You never know,” Scott said. “Everyone is up against it tomorrow. I mean, the guy is such a good front-runner, he gets so focused. And we've seen this year how good he finishes out tournaments and shuts the field out on Sunday.

“We're all up against it, that's for sure. But all you can do is go out and play your best golf and put a good score on the board, and if it's not good enough, then you've got to do better next time.”

Scott has been playing very well on the PGA TOUR this year. All that’s missing is a victory, which would be his first since the 2004 Booz Allen Classic. The 26-year-old has eight top-10s in 16 starts, including one stretch with four straight finishes of fourth or better.

In nine events on the European Tour, Scott has five top-10 finishes, including in his last four starts. Earlier this month, he won the Singapore Open, beating Ernie Els in a three-hole playoff, and rose to fifth in the Official World Golf Ranking.

“Adam has obviously been playing well,” Woods said. “It’s a case where confidence does a lot for you, and we’re both feeling that way. It should be good tomorrow.”

Perhaps Scott’s best chance to win on TOUR this year came at the EDS Byron Nelson Championship where he owned a share of the lead after each of the first three rounds. That closing 71, though, simply wasn’t good enough to hold off a hard-charging Brett Wetterich.

“I base my success of the year on winning, and last year was great, I won three times (internationally), and this year only once,” Scott said. “I think I should be looking to do better than that. I had my opportunities, no doubt.

“But like I said, I didn't close out very well on Sunday, and a couple guys had gone past me. I have to learn from that, and next time I'm in the position, I need to really finish it off on Sunday early.”

Scott gets another chance on Sunday at The Grove -- and against the most formidable opponent ever. The two leave the first tee at 10:47 a.m. (5:37 a.m. ET) as officials try to combat a forecast of heavy rain and thunderstorms.
