OAKVILLE, Ontario – Jason Day birdied the final three holes to win the Canadian Open on Sunday, spoiling David Hearn's bid to become the first Canadian winner in 61 years.

Day made a 20-foot putt on the par-5 18th for a 4-under 68 and a one-stroke victory over Bubba Watson. Day finished at 17-under 271 at Glen Abbey.

Day was coming off a fourth-place tie Monday in the British Open at St. Andrews. The 28-year-old Australian also fought through vertigo symptoms last month to tie for ninth in the U.S. Open. He has four PGA Tour victories, also winning at Torrey Pines in February.

Watson birdied the final four holes for a 69.

Hearn, two strokes ahead of Day and Watson entering the round, had a 72 to finish third at 15 under.

Pat Fletcher, born in England, was the last Canadian winner in 1954 at Point Grey in Vancouver, British Columbia. Carl Keffer is the only Canadian-born champion, winning in 1909 and 1914. Albert Murray, a Canadian also born in England, won in 1908 and 1913.
