While the New Zealander had her sights set on a third consecutive major, it was the 18-year-old Canadian who caps Ko at the post by snatching the victory from him on the first play-off hole, with a final score of 65 ( -6 total) Sunday at Sahalee Country Club. Henderson becomes the youngest winner in the history of this 62-year-old Grand Slam tournament.

"Yes, it's fantastic to think of all the incredible players who have won this tournament before me"said Henderson.

“The last two days the public support has been really amazing. Walking the fairway and hearing my name scream it was really amazing. But last time around, they just screamed Go Canada. And it was kind of a surreal feeling. I can't really put into words how I'm feeling. I am happy to be the Canadian face of women's golf and I would be proud to represent Canada for the Olympics. "

Ko retains the status of the youngest major winner in history at 18 years and 4 months, after her success last year in Evian.

Thailand's Ariya Jutanugarn ends her streak of three consecutive titles by finishing third just one stroke from the playoff. The three young women of 19 years of average age flew over the test in Seattle. The only French qualified for the weekend, Céline Herbin finished 46th (+10)
