BEDMINSTER, N.J. (AP) — Sung Hyun Park picked a big stage to capture her first LPGA Tour victory.

The 23-year-old South Korean shot her second straight 5-under 67 to take the U.S. Women's Open in New Jersey. She was immersed in a day-long battle with front-running Shanshan Feng and teenage amateur Hye-Jin Choi before moving in front with birdies on the 15th and 17th holes.

Park's 11-under total was two strokes better than Choi, who double-bogeyed 17 to lose her share of the lead.

Top-ranked So Yeon Ryu and fellow South Korean Mi Jung Hur tied for third at 7 under.
