THOUSAND OAKS (California) (AFP) - Tournament host Tiger Woods had two eagles in a five-under 67 on Friday to seize a three-shot halfway lead in the Chevron World Challenge. Woods, the 14-time major champion who is seeking his first victory in more than two years, had a 36-hole total of eight-under par 136. Overnight leader K.J. Choi and American Matt Kuchar shared second on 139. Zach Johnson and Hunter Mahan were tied on 140, Johnson carding a 67 and Mahan a 68. South Korea's Choi started the day with a three-shot lead and managed to keep his nose in front for much of the day. He was undone, however, by a quadruple-bogey seven on the par-three 15th. Choi managed to bounce back with a birdie at the par-five 16th, his one-over 73 good enough for a share of second after Kuchar -- who teamed with Gary Woodland to win the World Cup for the United States in China last week -- bogeyed 18 for a five-under 67. The biggest blot on Woods' card was his own double-bogey on 15, where he was in the water off the tee.
