ANCASTER, Ontario -- Arron Oberholser shot a 2-under 68 in windy conditions at the Canadian Open for a share of the second-round lead with Jesper Parnevik, Camilo Villegas and Jonathan Byrd on Friday.

The 31-year-old, a three-time winner in Ontario province, put himself in position to try to add the biggest Canadian title of them all.

"Ontario has been good to me. Canada has been good to me," Oberholser said. "I enjoy playing up here. I enjoy the people. I enjoy the atmosphere."

Oberholser, the AT&T Pebble Beach National Pro-Am winner in February for his first PGA TOUR title, won two Canadian Tour events in Ontario in 1999 and also took the Nationwide Tour's 2002 Canadian PGA at DiamondBack in Richmond Hill.

"I spent two great years up here on the Canadian Tour learning how to play," Oberholser said. "Drove the country twice. I've probably seen more of Canada than most Canadians. It was fantastic. I still regard those days as the most fun I've ever had playing golf. It was a great time."

While the greens were still soft and receptive on the 90-year-old Hamilton Golf and Country Club course, gusting wind on the warm and sunny day made scoring far more difficult than it was in calm conditions on Thursday.

"It was completely different. The wind was blowing really hard," said Parnevik, who also had a 68 to join the leaders at 7 under. "This is a very tough course to start with. When you get wind like this, probably gusting 25 mph at times, when you're in the trees, it's tough to figure out which direction it is blowing."

Oberholser, who shot a 65 on Thursday, made only two bogeys in the first 36 holes, both on the par-3 sixth. On Friday, his tee shot on the uphill, 210-yard hole sailed left, hit a cart path and landed behind a grandstand. He got a drop 60 yards from the hole on a teeing area on the fourth hole, hit to 10 feet and just missed his par try.

"I don't have a club for that hole," Oberholser said. "5-wood is too much. 3-iron is not enough. I told my caddie, `Tomorrow, we're just laying up.' I left my 19-degree, which is the perfect club for that hole, at home. I'll be laying it up, trying to get it up and down the next two days."

Villegas shot a 64 in the tricky wind conditions.

"It wasn't easy out there," he said. "The wind was blowing. It was gusting. But I managed to roll some great putts."

The young Colombian player holed a 30-yard birdie chip on the par-4 11th and made a 60-foot putt on the par-4 15th. "Might be the longest putt I ever made," he said.

Byrd, seeking his third TOUR title, birdied his final three holes for a 68.

"I'm excited to be in this position," he said. "I feel comfortable on this course."

Brett Quigley matched the course professional record with a 63 to join first-round leaders Jim Furyk and Justin Rose in a large group at 6 under. Furyk and Rose had 71s a day after shooting 63s to break the course record of 64 set by Tommy Armour in the 1930 tournament. Warren Sye set the overall record of 62 in the 1991 Ontario Amateur.

"For some reason, I think I have a tendency to play a little better when the conditions are tougher," Quigley said. "I think it's just a matter of focus for me."

Trevor Immelman (66), Eric Axley (66), Tom Pernice Jr. (68), Ryuji Imada (68), Sean O'Hair (69) and Nathan Green (70) also are 6 under.

Canadian star Mike Weir missed the cut in the national championship for the second straight year and 11th time in 16 starts. He followed an opening 71 with a 74 to finish at 5 over, five strokes off the weekend cutoff.

"I just didn't play well," said Weir, who hit only four of 14 fairways in regulation in the second round and 13 of 28 overall. "If you're playing out of the rough, you're going to have trouble scoring."

Fellow Canadian Stephen Ames withdrew after nine holes because of a strained back. THE PLAYERS Championship winner was 4 over for the round and 5 over for the tournament.

"I wanted to continue, but it was wise to stop," Ames said.

Vijay Singh, the 2004 winner in a playoff with Weir, is four strokes back after a 69.

Defending champion Mark Calcavecchia shot a 74 to make the cut by a stroke.

Among those who missed the cut were Bob Tway, the 2003 winner on the Hamilton course, and U.S. Ryder Cup rookie Vaughn Taylor, who followed his opening 79 with a 67. He missed the cut by six strokes.
