Jim Furyk fired a hole-in-one on his way to a brilliant final-round seven-under 64 to take out his second successive Canadian Open as Australian Steve Allan slipped down the leaderboard with an even-par round. The American made birdies on the first and third holes, before his ace on the fourth saw him grab the lead from overnight leader Vijay Singh. Furyk maintained that one-stroke margin for the remainder of the round to finish on 16-under ahead of Singh, with Americans Ryan Palmer and George McNeill tied for third on 13-under. It was Furyk&aposs 13th PGA Tour victory as he became the first player to successfully defend the title since Jim Ferrier won the second of his Canadian Opens in 1951. Allan, who led the field at the halfway mark of the tournament, could only manage an even-par 71 to finish at 11-under in a tie for seventh. Compatriot Paul Gow had a closing three-under 68 to finish on 10-under, while Stephen Leaney fired five birdies in the last round to be one stroke further back. Steve Elkington also had a final-round 66 to finish at eight-under.
