Tiger Woods maintained a three-stroke lead by shooting a convincing three-under-par 67 in the second round of the Dunlop Phoenix tournament in Miyazaki, Japan.
Seeking his first win on the Japan tour, the five-time US former world number one carded four birdies against one bogey for a two-round total of eight-under-par 132, ahead of Japan's Kaname Yokoo.
Yokoo, the winner in 2002 when Woods finished eighth in his previous appearance here, also hit a 67 with five birdies against two bogeys on the 6,901-yard, par 70 Phoenix Country Club course in western Japan.
American Christian Pena hit the day's best of 63 to move up to third place on 136, followed by Japan's Ryoken Kawagishi and Choi Kyoung-Ju of South Korea two strokes further back.
Defending champion Thomas Bjorn of Denmark hit a 69 to be tied at 32nd place with four Japanese on 144, while British Open champion Todd Hamilton of the United States had a disastrous 76 for a 60th-place tie on 149, narrowly clearing the cut line.
A total of 65 golfers who marked nine-over-par 149 or less advanced to the third round of the $1.9 million event.
