Choi finished at 10 under on Sky 72 Golf Club’s Ocean Course for her second LPGA Tour victory of the year and fourth in two years. She earned $270,000 to take the top spot on the money list with $1,742,028.
“I am really happy to defend my title,” said Choi, a playoff winner in July in the Jamie Farr Classic. “There were a lot of expectations from the fans that I have to defend my title. In order to live up to those expectations, I had to let everything out on the course and concentrate on every shot. That paid off.”
Hurst closed with a 70.
“I played very steady, and that was my goal,” Hurst said. “My mom told me to just be patient and stay calm, keep going, making pars and birdies. And I did that, so I’m pretty proud of myself. … It was a great week.”
Second-round leader Song-Hee Kim (73) was third at 7 under.
“Even though I am best friends with Song-Hee, I can’t think about friendship on the course,” Choi said. “It’s all about competition on the course. I made my effort to focus on the game. If I thought about the friendship with Song-Hee, I could have not concentrated on my game the way I did.”
Kim has five runner-up finishes in her winless LPGA Tour career.
“I was a little bit disappointed by the result, but at the same time, I think I did my best,” Kim said.
U.S. Women’s Open champion Paula Creamer (67), second-ranked Jiyai Shin (69) and Suzann Pettersen (70) followed at 6 under.
Michelle Wie shot a 70 to tie for 12th at 3 under in a group that included top-ranked Cristie Kerr (71) and 50-year-old Juli Inkster (74).
