Two-time winner Jim Furyk birdied two of his last four holes Friday in the Canadian Open to match the Royal Montreal record at 7-under 63 and tie Tim Petrovic atop the leaderboard.
The 44-year-old Furyk, the 2006 winner at Hamilton and 2007 champion at Angus Glen, matched Petrovic at 10-under 130 on the tree-line Blue Course.
The 47-year-old Petrovic followed his opening 64 with a 66.
Canada's Graham DeLaet, playing in a threesome with Furyk and Matt Kuchar, was two strokes back along with Kyle Stanley. DeLaet, trying to become the first Canadian winner in the event in 60 years, also had a 63. Stanley shot 67.
Graeme McDowell had a 65 to top the group at 7 under.
Michael Putnam, tied for the first-round lead with Petrovic, was 6 under after a 70. Kuchar also was 6 under after a 65.
