KOHLER, WI (WSAU) Na Yeon Choi won the U-S Women’s Open in Kohler yesterday by four strokes over fellow South Korean Amy Yang. Choi led by six strokes after Saturday’s third 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 one-over-par 73 yesterday and finished at seven-under-281.

She was the fourth South Korean player in the last five years to win the U-S-G-A’s premier women’s event. Yang finished at minus-three, and she and Choi was the only players to finish under par.

Sandra Gal of Germany was third at one-over. Paula Creamer was the top American, finishing seventh at three-over. Pak tied for ninth at plus-four. Second-round leader Suzann Pettersen (pet’-er-sen) also tied for ninth. 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 leader-board 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 three-over 75 yesterday, and was 12 over for the Open.
