New Zealand teenager Lydia Ko became the first amateur to win two LPGA Tour events by shooting a final-round 64 to defend her CN Canadian Open title with an astounding five-shot victory in Edmonton, Alberta, on Sunday.
Ko, 16, entered the final round training Sweden's Carolina Hedwall by one stroke, but Ko's 6-under-par round of 70 was three shots better than anyone else in the field. She finished the tournament at 15-under 265 at Royal Mayfair Golf Club.
"I'm pretty surprised, but I played some really good golf out there, so I was really happy about that," Ko said. "My goal today was to shoot 5 under and just play my own game. If somebody else shot better, then I can't do anything about it."
France's Karine Icher shot a 3-under 67 to take second place at 270. Hedwall finished in a tie for third place at 271 along with American Brittany Lincicome.
"This is one of my better finishes on the LPGA, so I'm very happy this week," Hedwall said. "I'm still waiting for my first win, but hopefully it will come soon. I slept OK, to be honest. I was just excited to come out and play today. I had a lot of fun out there. It's just that Lydia was way too good today."
Ko won the CN Canadian Open in 2012 at Vancouver Golf Club in Coquitlam, British Columbia, becoming the youngest winner of an LPGA event at 15 years, 4 months, 2 days. A year later, she now holds the top two spots on that chart.
"When I saw that record, I thought, 'Wow, that is amazing,'" Ko said. "Who can do that? And to have done that myself, that's pretty special. Last year was a three shot (win), ... so I was pretty happy about that. Now having five shots, it makes it even better."
With the victory, Ko will move from No. 19 in the Rolex Women's World Rankings to No. 7. It is her fourth international victory worldwide.
Ko is the first LPGA player to defend a title since Yani Tseng won the RICOH Women's British Open in 2010 and '11.
Ko has not missed a cut in 14 LPGA events over the past two seasons.
