Bedminster: South Korean golfer Sung Hyun Park has won the US Women's Open by two strokes at Trump National for her first major championship.
The 23-year-old Park carded a closing five-under-par 67 to finish at 11-under 277 on Sunday.
Park's compatriot, amateur Hye Jin Choi, finished second after a one-under 71 to be nine under, while another two South Koreans, Mi Jung Hur (68) and So Yeon Ryu (70), shared third spot at seven under.
Australia's Minjee Lee made a late charge, closing with a six-under 66 to finish in a tied 11th at four under.
The 23-year-old Park won a day-long battle with front-running Shanshan Feng and teenager Choi.
Park needed a fine chip from over the green on the par-five 18th hole to save par and win the $US900,000 ($1.1 million) top prize from the $US5 million ($6.4 million) event.
Feng, from China, had a 75 to drop into a tie for fifth at six under with Spain's Carlota Ciganda(70) and South Korea's Jeongeun Lee (71).
