Korean teenager Inbee Park became the youngest player to win the US Women's Open when she scored an emphatic four-stroke victory today.
Park, who turns 20 on Saturday week, completely outplayed her rivals in the final round, carding a brilliant two-under-par 71 in strong winds at Interlachen.
She finished at nine-under 283, becoming the third Korean to win the most prestigious title in women's golf after Se Ri Pak (1998) and Birdie Kim (2005).
"I am very honoured to win this event. It's been 10 years since I started playing golf and it's finally happened," said Park, who was inspired to take up the game by Pak's victory a decade ago.
Park, who started the final round two strokes behind overnight leader Stacy Lewis, wasted no time taking the lead with birdies at the first two holes, and never surrendering it.
She pulled away with a near flawless back nine, displaying poise beyond her years to leave everyone else playing for second.
Park, who did not have a three-putt the entire tournament, built her lead to five strokes with just two holes left and a bogey at the par-four 17th was merely academic.
She finished in style with a tap-in birdie at the par-five 18th, while Swede Helen Alfredsson (75) also birdied the last to claim second place on five-under.
Lewis collapsed with a 78 to finish another stroke back in a tie for third with Korean In-Kyung Kim and Brazilian Angela Park.
Swede Annika Sorenstam, playing her final US Open, finished in style with an eagle at the last much to the delight of the huge gallery.
Sorenstam tied for 24th, a distant 12 shots off the pace, while Karrie Webb was best Australian, 15 strokes behind in a tie for 38th.
Only three players hit more greens in regulation than Webb, who struggled with her putter.
"That's been my story for a couple of years," she said.
Fellow Australians Lindsey Wright, Rachel Hetherington and Katherine Hull finished one shot further back, equal 42nd.
