Sung Hyun Park carded a five-under 67 to win the US Women’s Open at Trump National in New Jersey by two shots at 11-under-par.
The Korean LPGA Tour rookie had back-to-back 67s during the weekend to finish two shots clear of compatriot and amateur Hye Jin Choi, who was unable to recover from her double bogey on the 16th hole on Sunday after finding water from the tee.
Park had begun the final round three shots back of Shanshan Feng, but had three birdies in her first eight holes before dropping her only shot of the day on the ninth.
The 23-year-old, who won seven times on the Korean LPGA Tour in 2016, then went on to post three more birdies at 12, 15 and 17 before getting up and down for par on 18 to secure his first LPGA Tour victory.
Following her round, Park said “To be honest I still cannot believe this is actually happening. It’s almost like I’m floating on a cloud in the sky”
Overnight leader Feng had a disappointing final round that ended in a triple-bogey on the 18th – seeing her take fall back to a share of fifth at six-under-par with Carlota Ciganda and Jeongeun Lee.
Korean players dominated the majority of the leaderboard's top 10 at the third major of the year, with Mi Jung Hur and World No.1 So Yeon Ryu sharing third place on seven under.
Sei Young Kim, Mirim Lee and Amy Yang were two shots further back on five-under to take a share of eighth.
Charley Hull was the top British player, finishing 21st at level par for the tournament having carded a one-over 73 on Sunday.
