The win is Kerr's 19th on the LPGA, and it's her first since taking the 2015 season-ending CME Group Tour Championship. She birdied seven of the last eight holes Friday, soaring into contention with the 62 and growing comfortable walking in her birdie putts before they fell in the hole. Made a lot of good par saves, and (made) some good birdie putts to start the day.
Jang, who held a three-shot lead at the end of the third round and led for much of Saturday, made double bogey on the par-three No. 8 and had a bogey on the par-five 14th to drop to 17-under.
Tied with Jang and In Gee Chun was World No.1 Lydia Ko, who fired rounds of 65-64 on the weekend.
Lee could have had the outright lead only to bogey her final hole in the dark, and play was suspended with six golfers still on the Ko Olina course.
Third-ranked Ariya Jutanugarn and Stacy Lewis tied for seventh, six strokes behind Kerr.
Michelle Wie finished the week 4 under for a tie for 39th.
"Going into the day eight shots behind there is a huge difference between eight shots and five shots", Ko said.
"Wow, I don't know what to say". But a fall at his rental home hurt his back the day before the year's first major was to start. He was one of nine players on 2-under and just a shot behind. "That (first) day and a half that I had struggled a little with my swing feel it was an unbelievable run".
"This week we really just tried to be aggressive from the get-go", said Salas, who broke 70 just twice in her first seven tournaments this year.
Su-Yeon, who was invited to the tournament by the sponsors, said: "Because I had to finish up the second round this morning and play another 18 I was a little bit exhausted".
Canada's Alena Sharp (66) and Cristie Kerr (62) of the U.S. are tied for second at 14-under 202 in the tournament which has featured weather delays in each of the first three rounds.
"I haven't been able to play as well as I would have liked. I think that experience will help me play in the rest of the round tomorrow".
