time champion Tiger Woods was let down by his approach play at the Memorial tournament on Friday as fellow Americans Jim Furyk and Jonathan Byrd moved into a tie for the lead after the second round. World number one Woods, bidding for his second PGA Tour victory this year, carded a two-over-par 74 in breezy conditions at Muirfield Village Golf Club to lie six shots off the pace. Byrd fired a flawless 68 in the morning for a seven-under total of 137 before being caught late in the afternoon by Furyk, who mixed five birdies with three bogeys for a 70. Canadian left-hander Mike Weir birdied three of the last five holes for a 69 to finish at six under, level with American Mark Wilson (70) in the event hosted by Jack Nicklaus. Japan's Ryuji Imada birdied three of his last four holes for a 69 to lie two strokes off the lead with American Matt Bettencourt. The cut fell at four-over 148 with several big names missing out. British Open champion Padraig Harrington (77), 1997 winner Vijay Singh (75) and Australian Adam Scott (81) were among those failing to advance. Pak, Pettersen share lead In Illinois, five-time major champion Pak Se-ri, winless for nearly two years, fired a four-under par 68 Friday to share the lead with Suzann Pettersen after two rounds of the LPGA State Farm Classic. Pak's bogey-free round at the 1.7 million-dollar event left her on 10-under 134 after 36 holes, level with Norway's Pettersen, who fired a second-round 66. One stroke off the pace were five players, including Sweden's Helen Alfredsson, whose impressive 63 on Friday included seven birdies, three of them in a row starting at 13, and an eagle at the 16th. Also on 135 were South Korean Jee Young Lee, who shared the lead with Pak after the opening round, and Americans Kris Tamulis, Kristy McPherson and Moira Dunn. Korean Jiyai Shin was eighth on 136. US tour rookie Michelle Wie fired a 68 to stand four off the pace. Monty in the race European tour rookie Richie Ramsay added a second-round 67 to his opening 68 to set the pace at the halfway stage of the Wales Open in Christchurch on Friday as his fellow Scot Colin Montgomerie put himself in position to challenge over the weekend. Montgomerie's second 69 left him at four under, three shots behind former US Amateur champion Ramsay, and the European Ryder Cup captain was delighted to be back on the leaderboard. Corey Pavin had a second successive 72 and only just made the cut. Ramsay was a shot clear of English pair Robert Rock (68) and Ross Fisher (66).
