Thailand's Ariya Jutanugarn chipped out of a bunker to lie within inches of the pin as she won the US Women's Open after a four-hole play-off against Hyo-Joo Kim.

Jutanugarn had gone into her final round at 12-under 204 with her South Korean rival sitting in third place, six shots adrift.

But Kim rallied at Shoal Creek, Alabama, going out in three-under and hitting two birdies coming in as she carded a bogey-free round of 67 on Sunday.

Jutanugarn, meanwhile, got to the turn in 32 but a triple-bogey seven on the par-four 10th rattled her as she went on to drop a further three shots on the remaining eight holes.

The pair then went into a play-off, where Kim took the early advantage carding a birdie on the par-four 14th, but then dropping a shot on the 18th.

Both players made par on the third play-off hole, before 2016 Women's British Open winner Jutanugarn saved par to win the title after a deft bunker shot on the 18th.

Speaking after her win, Jutanugarn said: "I'm really honoured to join the list of players before me.

"If you have a seven-shot lead and then go into a play-off, you have no expectation.

"I got mad a little bit about what happened in my back nine, but I thought if I have to play off, I have to do my best on every shot."

Carlota Ciganda came in third on seven-under, amateur Patty Tavatanakit was fifth on two-under while England's Charley Hull was among seven players tied for 10th on par.
