THOUSAND OAKS, Calif. – Tiger Woods is starting to look like his old self at the Chevron World Challenge.

Woods got off to a blazing start Friday and a solid putting stroke enabled him to play bogey-free in the second round for a 6-under 66 that gave him a four-shot lead going into the weekend of his final tournament this year.

Woods was at 13-under 131, his best 36-hole score this year by six shots. And the four-shot lead over U.S. Open champion Graeme McDowell had to be a refreshing change for a guy who has been at least nine shots back through 36 holes in seven tournaments this year.

“I’ve been here before, so it’s not a strange feeling,” Woods said. “It’s just one of those things where tomorrow is the same game plan, just go out there and plot my way along and take care of the par 5s.”

He did that again on a pleasant day in the Conejo Valley, and now has played the five par 5s at Sherwood Country Club in 10 under through two rounds. That included an eagle on the second hole, and perhaps Woods’ most impressive shot of the day, if not the year.

He hit a 4-iron from a hanging lie so severe that it caused Woods to stumble down the hill after impact.

The ball landed 8 feet away to the right of the pin.

And on the next hole, when Woods made a superb par save with a putter through a swale to about 3 feet, caddie Steve Williams walked off the green and said, “The tide is turning.”

McDowell keeps plugging away in his sixth straight week of competition, playing well enough to keep pace except for a few mistakes. He took a double bogey on the ninth hole, and failed to save par from a bunker on the 18th.

He was at 9-under 135, and will be paired with Woods in the final group Saturday.

“Sometimes in a four-round tournament, you get a round where you don’t really play your best,” McDowell said. “To shoot 3 under and not play my best, I’m pretty happy with that.”

Rory McIlroy played with Woods for the first time in competition — the Skins Game at the Memorial doesn’t count — and was impressed with what he saw. McIlroy caught flak at the Ryder Cup for saying he would love to play Woods if his game didn’t improve.
