David Hearn moved into position to become the first Canadian to win the Canadian Open in 61 years, taking a two-stroke lead over Bubba Watson and Jason Day on Saturday.
Hearn, from Brantford, birdied the par-3 15th and par-5 16th, but dropped a stroke on the par-4 17th and closed with a par for a 4-under 68 and a 15-under 201 total at Glen Abbey.
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.
Watson also had a 68, and Day shot 69. Watson eagled the par-5 13th, made a bogey on the par-4 14th and rallied with birdies on 16 and the par-5 18th.
Day, coming off a tie for fourth Monday in the British Open, dropped three strokes with a bogey on the par-4 10th and double bogey on the par-4 11th, then birdied six of the last seven holes.
