PRIDDIS, Alberta - Ariya Jutanugarn ran away with the Canadian Pacific Women's Open on Sunday at chilly Priddis Greens for her LPGA Tour-leading fifth victory of the year.
Nine days after withdrawing from the Rio Olympics because of a left knee injury, the 20-year-old Thai player made a 12-birdie putt on the final hole for a 6-under 66 and a four-stroke victory.
Bundled up in a winter jacket between shots with the temperature in the lows 50s on the overcast afternoon, the second-ranked Jutanugarn matched the tournament record for relation of 23 under set by So Yeon Ryu two years ago at London Hunt in Ontario and the mark for strokes of 265 set by Ryu and also accomplished by Lydia Ko in 2013 at par-70 Royal Mayfair in Edmonton.
South Korea's Sei Young Kim, a two-time winner this year, was second after a 65.
After a late meltdown cost of her first LPGA Tour victory in April in the major ANA Inspiration, Jutanugarn won three straight events in May. She won the Women's British Open in the event before the Olympics, and made it two in a row on the tour Sunday in the foothills of the Canadian Rockies.
The long-hitting Jutanugarn, blasting 2-iron and 3-wood off the driving holes on the tree-lined course, birdied the par-5 seventh and par-3 eighth to get to 19 under, then pulled away with birdies on the par-5 12th, par-4 14th, par-3 15th and par-5 18th.
South Korea's In Gee Chun, the 2015 U.S. Women's Open champion, was third at 18 under after a 69.
Canada's Alena Sharp had the best result of her LPGA Tour career, birdieing the final two holes for a 67 to finish fourth at 16 under.
Australia's Karrie Webb (64) and Sweden's Anna Nordqvist (68) tied for fifth at 15 under. Webb won the 1999 du Maurier Classic, the then-major championship that folded because of Canada's restrictions on tobacco promotions, at Priddis Greens. She was second behind Suzann Pettersen at the course in 2009.
Three-time champion Ko had a 69 to tie for seventh at 13 under. She won three of the previous four years, the first two as an amateur. The 19-year-old New Zealander is No. 1 in the world and has four victories this season.
Canadian star Brooke Henderson shot a 69 to tie for 14th at 11 under. The 18-year-old Henderson beat Ko in a playoff in June in the KPMG Women's PGA Championship for her first major title, and successfully defended her Cambia Portland Classic title last month. She will play in her home province next week in the Manulife LPGA Classic in Cambridge, Ontario.
