Brooke Henderson ended Canada's long drought at the CP Women's Open on Sunday, firing a final round 7-under-par 65 to win the national championship by four strokes. Henderson finished with a 21-under 267 total, sealing the win with a short birdie putt on the 18th hole at the Wascana Country Club. American Angel Yin was alone in second place after a 68 and American Jennifer Song (67) was six shots behind at 15 under. Australians Minjee Lee (68) and Su Oh (69) were seven strokes off the pace in a fourth-place tie with South Korea's Amy Yang (68) and American Austin Ernst (69). It was the first time a Canadian has won this tournament since Jocelyne Bourassa took the 1973 event - then called La Canadienne - at Montreal Municipal.
