Park Sung-hyun wins US Women's Open by two strokes

The South Korean juggernaut continued as long-hitting Park Sung-hyun broke a three-way tie with two late birdies to win the US Women's Open by two strokes at Trump National Golf Club in New Jersey, USA on Sunday for her first major championship.

The 23-year-old Park, runaway favourite to win LPGA Rookie of the Year honours, birdied the par-five 15th to forge ahead and, after co-leader amateur Choi Hye-jin double-bogeyed the 16th, added a six-foot birdie at the 17th for some cushion.

Park, who won seven times on the Korean LPGA Tour in 2016, saved par at the par-five 18th with a superb chip from a tight lie behind the green to post a five-under-par 67.

As the poker-faced Park made her way from the 18th green to the scoring tent, she paused to wave and bow towards US President Donald Trump, who looked down from his bullet-proof, glass-enclosed private box.

"To be honest I still cannot believe this is actually happening. It's almost like I'm floating on a cloud in the sky," Park said through an interpreter after signing for 11-under 277.
