Phuket:Oliver Wilson carded a six-under-par 66 in the second round of the Johnnie Walker Classic on Friday to top the leaderboard at ten under-par. Adam Scott endured a poor start to the event with an opening round 74. But the Australian, the 2005 champion, carded a second round three-under-par 69 and moved to one-under for the tournament, making the cut in the process. Colin Montgomerie bounced back from a double-bogey at the par-three 17th to finish the day tied for 11th place. The Scotsman birdied the last - his sixth of the round - to card a two under-par 70. Thongchai Jaidee is the highest placed Thai on the leaderboard, tied with Montgomerie and six others at five-under. Turning point Â Following an opening round 71, Jaidee sat at one-over after eight holes on Friday. However, an eagle putt at the ninth proved to be the turning point in his round and Jaidee picked up three birdies after the turn on the way to a four-under-par 68. Lying in joint tenth place after the first round, Retief Goosen moved into contention with a second successive four-under-par 68. The South African carded his sole bogey of the day at the first, but responded with birdies at the sixth and eighth holes. Further shotsÂ Three further birdies on the back nine saw Goosen finish the day at eight-under. Joining Goosen in third place on the leaderboard was James Nitties. The Australian reached the turn in three-under 33 following three birdies. He picked up further shots at the 15th and 18th holes for a bogey-free five-under-par 67. The joint best round of the day was produced by South African Anton Haig. More birdies Starting the day six strokes off the pace, Haig picked up four birdies before the turn, carded another at the 10th and eagled the 13th. The South African's only bogey came at the 14th, but two more birdies gave Haig an eight-under-par 64 that saw him move into second place at nine-under. Haig finished the day one stroke behind leader Oliver Wilson. The Englishman played a solid front nine and reached the turn at two-under 34. However, two eagles on the back nine, at the 11th and 15th, and a birdie at the 14th took Wilson to 11-under for the tournament. A solitary bogey came at the last, but Wilson still claimed the lead at the halfway stage, moving to ten-under with a six-under-par 66.
