SECOND ROUND LEADERBOARD Tiger Woods fired a course record of 10-under 62 to take a four-shot lead at the halfway stage of the Target World Challenge in California.
The world number one hit eight birdies and an eagle in his quest for his eighth tournament victory of the year.
"I am very pleased with the way I hit the ball," said Woods.
Overnight leader Jim Furyk carded a round of 67 to stay in the hunt, while Padraig Harrington hit the same score to go fourth behind Zach Johnson.
Woods's round at the Sherwood Country Club was his best score since his 61 at the 2005 Buick Open.
He improved the previous record of 63 set by Harrington in 2002 and equalled only by David Love and Michael Campbell.
Birdies on the second, fifth and sixth holes saw the three-time champion take the outright lead from fellow American Furyk.
Woods nearly holed out at the sixth, but his tee shot hit the front of the cup and then spun back to within six inches.
He followed that up with a beautiful approach shot to within six feet of the pin on the ninth.
He saved his best for the back nine, starting with a 20-foot putt for an eagle three on the 11th, soon followed by further birdies at the 12th and 13th.
He collected his seventh birdie of the day with a brilliant 30-foot on the 17th before signing off with yet another on the 18th.
"I hit some good shots but I made some bombs out there," said Woods, who carded a double bogey on the 18th on Thursday.
"The only difference today was I made some good putts. I didn't throw away a good round like yesterday."
Birdies on the last two holes ensured Furyk was within reasonable range of Woods at nine under, while Johnson, who birdied the last three holes for a 67, is another shot behind.
Colin Montgomerie made a vast improvement on his disastrous first round of 80, carding a 67, but is in penultimate place on three over.
