KOHLER, WI (WTAQ) - Na Yeon Choi won the U.S. Women’s Open in Kohler Sunday by four strokes over fellow South Korean Amy Yang.

Choi led by 6 strokes after Saturday’s 3rd round at Blackwolf Run. She triple-bogeyed the 10th hole in her final round, but she recovered to win on the same course where Se Ri Pak won South Korea’s first major title in 1998.

Pak and a group of friends gave Choi a champagne shower and lots of hugs after she putted out on the 18th green. Choi shot a 1-over par 73 Sunday and finished at 7-under 281. She was the 4th South Korean player in the last 5 years to win the USGA’s premier women’s event.

Yang finished at minus-3, and she and Choi was the only players to finish under par.

Sandra Gal of Germany was 3rd at 1-over. Paula Creamer was the top American, finishing 7th at 3-over. Pak tied for 9th at plus-4. Second-round leader Suzann Pettersen also tied for 9th.

Michelle Wie finished at 10-over 298, after being within a stroke of the lead on Friday. Wie shot 78 and 80 during the weekend to fall down the leaderboard in a tie for 35th.

Top-ranked Yani Tseng finished at 14-over. She still needs a Women’s Open victory to complete a career grand slam.

15-year-old Lydia Ko of New Zealand was the top amateur at Kohler. She shot a 3-over 75 Sunday, and was 12-over for the Open.
