Robert Garrigus broke the 54-hole scoring record at the Canadian Open that was set more than a half-century ago by Arnold Palmer.
His next job is to finish like the King.
On rain-softened greens that took the bite out of Hamilton Golf & Country Club, Garrigus used his power and some timely putts Saturday for a 6-under 64 that gave him a one-shot lead over William McGirt, who lost ground with a 66.
Garrigus was at 16-under 194, one shot better than Palmer in 1955 at Weston Golf & Country Club, and matched two years ago by Dean Wilson at St. George's Golf & Country Club.
Palmer went on to win in 1955 for the first of his 62 PGA Tour titles. Garrigus will be going for his second.
