COQUITLAM, British Columbia (AP) -- Lydia Ko won the Canadian Pacific Women's Open for the third time and first as a professional Sunday, beating Stacy Lewis with a par on the first hole of a playoff.
The 18-year-old Ko finished with an even-par 72 to match Lewis at 12-under 276 at Vancouver Golf Club. Lewis, also a playoff loser this year in the ANA Inspiration, had a 67.
Ko won in 2012 at Vancouver Golf Club at 15 years, 4 months to become the LPGA Tour's youngest winner and fifth amateur champion. The New Zealander successfully defended her title in 2013, also as an amateur, in Edmonton, Alberta. She has three victories this year to push her career total to eight.
So Yeon Ryu, the winner last year at London Hunt in Ontario, tied for third with fellow South Korean player Sei Young Kim at 11 under. Ryu had a 64, and Kim shot 68.
