Augusta (Georgia):Kenny Perry, trying at 48 to become golf's oldest major champion, fired a bogey-free five-under 67 in swirling wind to match Chad Campbell for the lead late in round two of the Masters.
Campbell, the 2003 PGA Championship runner-up seeking his first major crown, and US Ryder Cup teammate Perry, seeking his first win in 42 major starts, each birdied the 18th to stand on nine-under 135 after 36 holes.
"That was probably one of the greatest rounds I've ever played," Perry said. "I was so comfortable out there. I don't know how to explain it. The wind is really swirling. You've got to be really careful out there. It was just easy."
Eight months past his 48th birthday, Perry would be four months older than fellow American Julius Boros, who set the major age win mark at the 1968 PGA Championship, and two years beyond Jack Nicklaus as the oldest Masters winner.
World number one Tiger Woods, seeking his 15th major title to pull three shy of matching Nicklaus' all-time record, took a second bogey in as many days at 18 to finish on par 72 and stand seven off the lead.
"A lot of wasted opportunities. I didn't get a whole lot out of my round again," Woods said. "I need to play better than I have, make a few more putts and get it going."
Woods, trying to become the first winner since Nicklaus in 1986 from outside the top 10 after 36 holes, birdied the sixth and eighth but followed each with a bogey. He birdied 15 but lipped out for par from seven feet at 18.
Perry, who missed the cut in five of eight prior Masters, opened with back-to-back birdies, added more at the par-3 12th and par-5 15th and hit his approach three feet from the pin on 18 for another to equal Campbell.
"It feels great but we're only halfway there," Campbell said. "There's a lot of golf to be played."
Campbell rolled in a tense 25-foot downhill birdie putt on the 18th that likely would have rolled well beyond the hole had it not dropped in the cup.
Argentina's Angel Cabrera, the 2007 US Open champion, fired a four-under 68 in the late afternoon to seize third on 136, two strokes ahead of American Todd Hamilton, the 2004 British Open winner, and three atop South African Tim Clark.
Anthony Kim, another US Ryder Cup player, set a Masters record with 11 birdies in his seven-under par 65, the day's low round. The old 18-hole birdie mark of 10 was set by Zimbabwe's Nick Price in the 1986 third round.
Kim, who shared 75th Thursday after a 75, was hoping to book a weekend stay in his Masters debut and wound up jumping into contention for a green jacket on four-under 140.
Joining Kim in sixth were Japan's Shingo Katayama, Spain's Sergio Garcia, South African Rory Sabbatini and American Jim Furyk.
Irishman Padraig Harrington, trying to become only the third man to win a third major in a row, fired a one-over 73 to stand on 142 with, among others, Woods and 51-year-old Scotsman Sandy Lyle.
A day after surrendering low scores with little wind, Augusta National fought back with stiff breezes. "When you get wind like that it makes it tons different," Campbell said. "You've got to be so much more precise and it makes it so much more difficult."
World number two Phil Mickelson, Australian Geoff Ogilvy and Fiji's Vijay Singh were in a pack on 141.
Defending champion Trevor Immelman, Japan's Ryuji Imada, Australian Stuart Appleby and Northern Ireland teen Rory McIlroy were among 50 who reached the weekend, making the cut on the number at one-over 145.
McIlroy surrendered five strokes in the last three holes to tumble back.
South Africans Ernie Els and Retief Goosen, Australian Adam Scott and Indian Jeev Milkha Singh missed the cut by a stroke.
Two-time British Open winner Greg Norman, 54, fired a 77 and missed the cut by two strokes.
South African legend Gary Player, 73, missed the cut in the last of his record 52 Masters starts.
