South Korean-born Ko finished the 72 holes on 13-under-par 275 at the Vancouver Golf Club course to beat Park Inbee by three shots. “I just came to make the cut and play the best,” said Ko. “I won and I’m going to get the trophy, and it’s amazing.”
Ko is 16 months younger than Lexi Thompson, who held the previous age record at 16 years, eight months. Thompson set the mark when she won the Navistar Classic last year.
