Two shots further back is South Korean Hyo Joo Kim, a bogey on the par-three fifth hole the only blemish on her round of 68.
Duane Smith sizes up the situation with clubhouse leader Sarah Jane Smith on the 18th hole of Friday's suspended second round of the U.S. Women's Open in Birmingham.
Smith carded her second straight five-under round for a 10-under total of 134 at Shoal Creek, where thunderstorms led to extensive delays on a course that had been soaked earlier in the week. She reached 16-under par with her birdie at the par 4, 9 hole to match Juli Inkster's record set in 1999 of the most strokes under par in a U.S. Women's Open.More news: Trump to meet with families of victims of Texas shooting
Jutanugarn hit her tee shot into the hazard on the 10th and then had a three-putt for a triple bogey.
"I felt pretty good", Jutanugarn said about her mood before the shot.
But Kim made bogey - her first of the day - on 18 while Jutanugarn made par again to send the format to sudden death. And while her 223 start on Tour didn't become her maiden victory, she will take away the invaluable experience of having contended for the first time in a major championship. I didn't sleep much last night and I'm really exhausted. Jutanugarn hit her bunker shot to a foot and the win to cap off an incredible week. A collapse that would have gone down in U.S. Women's Open lore was about to be averted. She is still chasing Smith, along with everyone else. She was in the final group with Jutanugarn, but had a 78 on Sunday to fall into a tie for fifth.More news: Wie has 'a blast' - and 3-under 69 - at US Women's Open
"I'm very happy", Ciganda said Sunday.
Her final round was her second-best of the tournament behind her 71 on the first day but it has left her languishing back in a five-way tie for 48th place. "I just want to keep working and win a tournament".More news: Priyanka Chopra & Nick Jonas Enjoy a Dinner Date in L.A.
