South Korea’s world number four Ko Jin-young had edged in front with a three-under 69 to finish on nine under.

Khang, 25, started the final round with a three-shot lead but dropped five shots to fall behind.

On the last hole, Khang regrouped to tie Ko with a par, which was enough for her to win.

Khang won his 191st career LPGA event in Vancouver.

I was like, ‘it’s just a matter of time; it’s going to happen,'” said the world number 27, who shot 74 on Sunday.

This course suited my game very well and I’m just thrilled to get my first.”

After three bogeys on the first 10 holes, Khang responded with back-to-back birdies to get back to 10 under par.

Despite four birdies and one bogey, Ko was able to snatch the lead after two more bogeys – the second on the 17th hole.

Khang managed to secure her first career play-off by claiming the fifth birdie on the par-four 18th.

Ko had won the Founders Cup for her 26th professional title in May, but a double bogey gave Khang the chance to earn her first LPGA title.
