CHANDLER'S CROSS, England -- Tiger Woods made another eagle on the 18th hole Friday in the World Golf Championships-American Express Championship, only this one didn't finish off a great round.

It pumped life into what had been a dull one.

Woods, who started on the 10th hole on Friday, went on to birdie four of his next six holes on his way to a 7-under 64 and his best 36-hole start in six years.

He is at 15-under 127 and has a five-shot lead over Ryder Cup partner Jim Furyk (65), who was among those who finished their second round in increasing showers at The Grove.

Furyk, who played his last five holes in 1 over, is joined by Stewart Cink (67) and David Howell (66) at 10-under 132.

Padraig Harrington had a 69 and was another shot back.

"We're only at the halfway point," Woods said. "The (winning) score is not going to be 15, so you've got to continue making birdies."

It was Woods' lowest over the first two days since he shot 64-61 at Firestone in 2000 to build a seven-shot lead at the World Golf Championships-Bridgestone Invitational. In the midst of his best year in golf, Woods went on to win that tournament by 11 shots.

He is getting closer to the 2000 standard with each round.

Woods already has won seven times this year on the PGA TOUR, including two majors (Masters and British Open ) and the World Golf Championships-Bridgestone Invitational at Firestone last month.

His 36-hole record on the PGA TOUR (26-6) is not nearly as daunting as having the lead going into the final round, although the way he is playing on a course that suits him doesn't leave the 60-man field optimistic.

Tim Herron was on the practice green after his round when someone asked him how he did.

"Couple under, so that's like 1 under for the tournament," Herron said. "What does that leave me, 14 shots behind Tiger?"
