Her latest was a four-stroke runaway victory in the Canadian Pacific Women's Open where she closed with a six-under 66 to finish at 23 under. It was a final round clinic for Jutanugarn, who rolled in seven birdies, including four in the last six holes, to cement the win in an event she almost withdrew from because of doubts about a knee injury.

The 20-year-old had withdrawn from the third round of the Rio Olympics because of pain in her left knee, which had not gone away by the time she reached Calgary for this latest tournament.

"I feel like I'm going to withdraw this week because my knee hurt so bad last week," Jutanugarn said. "But when I got here on Monday and Tuesday, it's getting a lot better, and first round its fine."

Jutanugarn was running hot despite the bitterly cold conditions on the final day. Using just a 2-iron and 3-wood from the tee on the par-4s and 5s, the long-hitting Women’s British Open Champion never looked like she would surrender her lead at any stage.

"I felt like I wanted to have fun and be happy," Jutanugarn said. "No matter what's going to happen, I can handle it.

“Because I just come back from like injury, like my knee hurt, and I feel like I really want to be happy on the course. I really want to have fun with my caddie on the course. That's the only key I want to be.”

Jutanugarn has come a long way in just her second year on the LPGA Tour. This time last year she was struggling to find form and missed 10 cuts in a row but she says a change of attitude has helped her start to win tournaments.

“When I start to miss first cut and I missed like 10 cuts in a row, and I just feel like at that time, the only focus, was I'm scared to miss the cut,” she said.

“I really want to make the cut. But after that I feel like I changed my focus, so right now my focus is like what's going to be good, like what I have to do to be good, so I'm thinking about like what is under my control, not thinking about anything else.” - Ariya Jutanugarn

Jutanugarn’s 23 under equalled the tournament record, which was set by Korea’s So Yeon Ryu in 2014 at London Hunt in Ontario.

Karrie Webb was the best of the Australians, storming into a share of fifth place with a flawless final round eight under 64, which included four birdies in her last four holes.

“Early on I really wasn't feeling it,” Webb said. “I made some good pars on the first few holes, and then I started to hit some better iron shots and made some putts.

“On the back nine, everything went in, which I haven't seen much this year, so it was good to see. It was fun.”

West Australian Minjee Lee (75) finished tied 35th at three under, while fellow Olympian Su Oh closed out with a four under 68 to finish two strokes further back in equal 44th place.
