Kim finished at 22-under after shooting a final round six-under 66, beginning her birdie run on the 7th at Highland Meadows Golf Club. The 26-year-old now has nine Tour titles, also winning the LPGA MEDIHEAL Championship in May in California.

"I really wanted another win, especially this week, because the last two weeks I play really bad," Kim said.


She played the final seven holes in even par, offsetting a birdie on 15 with a bogey on 16, and is now focused on winning her first major title, with The Evian Championship and Women's British Open coming up.

"I haven't had a win the major tournament yet," Kim said.

"I think I try too much when I play the major tournament. I just play the same as regular tournament, even major ... Just let it go. Let it happen."

Thompson, a stroke behind Kim entering the final day, closed birdie-eagle for a 66.

"She played some amazing golf ... I didn't have my best ball-striking day, but five under, finished well. She played amazing. It's very well deserved," Thompson said.

Stacy Lewis was third at 16-under after a 66 while US Women's Open champion Jeongeun Lee6 had a 69 to finish fourth at 14-under.

Victorian Su Oh shot a final round two-under 69 to end in a tie for 19th while compatriot Minjee Lee also finished at eight-under after a final day 70.
