THOUSAND OAKS, Calif. -- The Santa Ana winds mostly faded to black, the scoring heated up with plenty of red numbers and tournament host Tiger Woods, in search of his first tournament victory since 2009, surged atop the Chevron World Challenge leaderboard after his white-hot ball-striking led to a 5-under-par 67 in the second round at Sherwood Country Club, an overall score of 8-under 136 and a three-shot lead heading into the weekend.
Four-time Chevron World Challenge champion Woods, the PGA TOUR's active leader with 71 victories and 14 major championships, who clinched the decisive point in the Americans' Presidents Cup victory in Australia 12 days ago, eagled the par-5 second and 11th holes on Friday. He backed his eagle on No. 11 with birdies on the next two holes.
Ten players shot under par in Friday's second round. Matt Kuchar and Zach Johnson matched Woods' second-round 67, while Hunter Mahan, Jason Day and Paul Casey shot 4-under 68s.
Kuchar, whose 20 top-10 results on the PGA TOUR in the past two seasons are second-most on Tour, sprinkled in seven birdies and pulled into a tie for second place with K.J. Choi at 5-under 139. First-round leader Choi notched five birdies on Friday, but fell back to three strokes off the lead due in large part to a quadruple-bogey 7 on the par-3 15th hole.
2007 Masters champion and 2007 Chevron World Challenge runner-up Johnson climbed into a tie for fourth with Mahan after beginning the day tied for ninth. A day after holing out a wedge shot from the second fairway that spun back from the rough on the back of the green into the cup for an eagle, Johnson registered six consecutive birdies from holes 6-11.
Other golfers recording second-round eagles were Southern California native and fan favorite Rickie Fowler -- who became the first to eagle the par-5 16th hole in this year's tournament and stands in sixth place at 3-under 141 -- Webb Simpson, who eagled Nos. 2 and 11, and Casey, who eagled No. 2.
