Jason Day birdied his last three holes to claim victory in the Canadian Open.
The Australian successfully made a 20-foot putt on the 18th hole to move to 17-under par, and neither David Hearn or Bubba Watson, who sat two shots behind him, could keep up to force a playoff.
Day hit a round of 68, while Hearn, who was the overnight leader, could only manage a 72 despite firing birdies on the first two holes.
Watson eventually finished second, after Hearn scored five on the final hole.
Veteran American Jim Furyk recorded his fourth top-five finish of the season with a round of 68, while Tom Hoge and former Open champion Stewart Cink came fifth.
