Allan and Mallinger lead in Canada

Markham, ON (Sports Network) - Steve Allan and John Mallinger are tied atop the leaderboard after Friday's second round of the Canadian Open at Angus Glen Golf Club.

Allan shot a three-under 68 while Mallinger fired a five-under 66 to finish 36 holes at 10-under-par 132.

Vijay Singh, the 2004 champion, posted a six-under 65 to vault into contention. He is tied for third place with Tripp Isenhour, who shot a 68 on Friday. The pair is knotted at nine-under-par 133.

Allan flew up the leaderboard early on Friday with a birdie at the third hole. He rattled off back-to-back birdies at six and seven and found himself atop the leaderboard at minus-10.

The Australian cruised along with six consecutive pars, but found trouble at the par-three 14th. Allan's ball came to rest in a bunker, where he blasted out 25 feet past the hole. He missed the par putt, but atoned for the error with a two-putt birdie at the par-five 14th.

Allan appeared to be in decent shape at the par-four 16th after he hit the fairway off the tee. His approach came up 30 feet short, but the problem came with his birdie putt. Allan left his birdie try five feet short and the 33 year old missed the par save.

Just like after his earlier bogey, Allan wasted little time in getting the stroke back. He hit a spectacular tee shot to inches to set up a tap-in birdie at the 17th.

Allan had some trouble with his approach at 18, missing left. He pitched to 10 feet and calmly holed the par putt to stay in a tie for the lead, his second 36-hole lead on the PGA Tour.

"One of my biggest faults in the past has been getting ahead of myself, so I definitely have to take it one shot at a time," said Allan, whose other second-round lead came at the 2004 Sony Open in Hawaii. "I'll probably try not to look at any leaderboards over the weekend, and just play as good as I can."

Mallinger, a 27-year-old Californian, began on the back nine Friday and wasted little time in breaking into red figures. He birdied the par-five 11th and added birdies at 15 and 17.

He sputtered a bit at the start of the second nine with six straight pars, but suddenly found himself one shot behind Allan after a three-footer for birdie at the seventh.

Mallinger played a good tee ball into the par-three eighth and converted for birdie from 13 feet. He had a 22-footer at the last to take first by himself, but missed the putt.

Still Mallinger has a share of the second-round lead for the first time. He has done it with some strong iron play considering he has missed only five fairways and six greens in regulation.

"I went home the last couple of weeks before Milwaukee, and just really worked on some drills with my golf coach," said Mallinger. "And my driving has been great this week. I think when you drive it well out here, you get some good looks at the pins."

Ryan Palmer (67) and Michael Putnam (68) are knotted in fifth place at minus- eight.

Defending champion Jim Furyk (66), Brandt Snedeker (68), Cliff Kresge (65) and Doug LaBelle II (68) are tied for seventh place at seven-under-par 135.

Overnight leader Hunter Mahan struggled on Friday. He posted a three-over-par 74 and fell into a tie for 11th place at minus-six.

The 36-hole cut fell at one-under-par 141 and among the notable players to miss the weekend were 2002 champion John Rollins (142), Kevin Stadler (143) and last week's winner in Milwaukee, Joe Ogilvie (146).
