Steve Allan is in a share of the lead with American John Mallinger at the halfway point of the Canadian Open on Friday after moving to 10-under-par 132 after two rounds at the Angus Glen Golf Club. After beginning the second round at seven-under, two strokes behind overnight leader Hunter Mahan, Allen moved to the top of the leaderboard with a three-under 68, while Mallinger carded a bogey free five-under-par 66. Mallinger is seeking his first win in just his 24th event, while Allan, who is playing in his 162nd tournament, has also never won on the Tour. Allan was bogey free through 13 after reaching the turn three-under-par before enduring a bogey-birdie-bogey-birdie run from 14 before finishing his round with a par at the last. “It&aposs nice to be up there, nice to be playing well,” said Allan. “But 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. I&aposll probably try not to look at any leaderboards over the weekend.” Mallinger, 27, ended his round with two birdies in his final three holes as the American make his 10th cut in 20 events this year. “You&aposve got to stay patient, you&aposve got to play within yourself,” he said. “It&aposs going to be a little new me being in the final group. I was in the second to last group at Pebble (Beach), so I&aposll take some of those experiences and see what happens.” World number six Vijay Singh shot up the leaderboard on Friday after carding a six-under 65 and is just one stroke off the pace alongside American Tripp Isenhour, while Ryan Palmer and Michael Putnam are a further shot adrift. “I haven&apost been on the leaderboard for a while, so I&aposm excited to be on the leaderboard. I&aposm looking forward to playing a solid weekend,” said Singh. Defending champion and world number three Jim Furyk carded a five-under-par second round 66 to move to seven-under after ending the first round tied for 35th after an opening round 69 on Thursday. American trio Brandt Snedeker, Cliff Kresge and Doug LaBelle II join Furyk on seven-under, while overnight leader Mahan shot a three-over-par 74 to drop to six-under after carding a course record 62 on Thursday. Canadian David Hearn endured a rough day on home soil after beginning the the round tied for third at six-under. Hearn plummeted into a tie for 27th after carding a two-over-par 73 to slip six shots off the pace, while countryman Stephen Ames is close behind at three-under. “The whole golf course is very soft,” said Ames. “And I hope the wind picks up a bit and drys it out even more and then maybe it will be a little sterner test instead of a bit of a biting competition, which is what it is right now.” Second Round of the Canadian Open: -10 Steve Allan (Australia) 64 68, John Mallinger 66 66 -9 Vijay Singh 68 65, Tripp Isenhour 65 68 -8 Ryan Palmer 67 67, Michael Putnam 66 68 -7 Brandt Snedeker 67 68, Jim Furyk 69 66, Cliff Kresge 70 65, Doug LaBelle II 67 68 -6 Dicky Pride 68 68, Brett Quigley 68 68, Bo Van Pelt 66 70, Camilo Villegas 68 68, Tom Pernice, Jr. 68 68, Hunter Mahan 62 74, Billy Andrade 69 67, Steve Marino 70 66, Michael Sim (Australia) 69 67 also: -5 Stephen Leaney (Australia) 70 67 -4 Mathew Goggin (Australia) 68 70 -3 Paul Gow (Australia) 70 69 -2 Jarrod Lyle (Australia) 75 65 -1 Steve Elkington (Australia) 72 69 missed cut: +1 Nathan Green (Australia) 69 74, Gavin Coles (Australia) 71 72 +2 Paul Sheehan (Australia) 71 73 +3 Grant Waite (New Zealand) 72 73, Andrew Buckle (Australia) 73 72 +4 Ben Ferguson (Australia) 74 72 +11 Adam Bland (Australia) 77 76 +16 Craig Perks (New Zealand) 77 81
