Teenage golfer Lydia Ko of New Zealand became the youngest player to win a LPGA Tour event when she captured the Canadian Women's Open by three strokes on Sunday.
Ko, 15, went 5 under par 67 to finish on 13-under overall in Vancouver.
She became the US Women's Amateur champion in Cleveland, Ohio, two weeks ago.
"It means a lot to me, it's a professional event and I just came to make the cut and play my best," Ko said afterwards.
''But to win and get the trophy is amazing. It's been a great couple of weeks."
Inbee Park of South Korea was second, 3 shots back. Three other South Koreans were third equal - 5 strokes behind Ko.
Anna Nordqvist of Sweden was next and then Stacy Lewis of the United States.
"I didn't have to do anything," said caddy Brian Alexander after the final round. "It was a remarkable performance."
In January, Ko, then 14, won the New South Wales Open in Australia.
The previous youngest LPGA Tour winner was Lexi Thompson, who won the Navistar LPGA Classic in Alabama last September, aged 16.
Only four other amateurs have ever won on the Tour. The BBC reports Ko is the first since JoAnne Carner in 1969.
