Jutanugarn led by three at the start of the final round. Following the 11th, she had fallen one behind Inbee Park - but then Jutanugarn holed out from the tee on the 145-yard 12th. A hole in one! And the lead was hers again.
Jutanugarn went three ahead of Park with a birdie on the 13th, bogied the 14th, then held her 2-shot advantage until the 18th. Park was already in the clubhouse at 12-under, and Jutanugarn was 14-under.
But things went badly awry on the final hole. Jutanugarn triple-bogied, dropped to 11-under, and Park had a 1-stroke win. Jutanugarn's triple included a penalty for an unplayable lie, chipping over the green, and leaving the return chip short of the green.
Had Jutanugarn held on, she would have become the third-youngest winner in LPGA history. In the past two years three of the six golfers in LPGA history to win before turning 19 have claimed their spots on that list:
- 15-year-old amateur Lydia Ko won the 2012 Canadian Women's Open, becoming the youngest-ever winner.
- 16-year-old Alexis Thompson won the 2011 Navistar LPGA Classic, at the time making her the youngest winner.
- 18-year-old Jessica Korda won the 2012 Women's Australian Open.
For Park, it was a win in her first LPGA start of the season. She was the tour's money leader and scoring leader in 2012.
