DUPONT — Cindy Ha, a 17-year-old from Demarest, N.J., shot a 5-under-par 67 to lead by a shot after the first round of stroke play Monday in the U.S. Women’s Amateur Public Links Championship at The Home Course.

The event, open to female amateurs who are public-course players, began in 1977 but is ending this year. Some of the biggest names in the sport, including Michelle Wie and Yani Tseng, are former champions, but the championship is being replaced by a Four-Ball Championship.

Ha, who will be freshman this fall at Vanderbilt, holds the one-shot lead over Gabriella Then from Rancho Cucamonga, Calif., who will be sophomore at USC.

Another shot back at 3-under 69 are former Washington and Portland State golfer A. Ram Choi and Annie Park, a USC junior-to-be who is ranked No. 11 in the world amateur rankings.

After the second and final round of stroke play Tuesday, the field will be cut to the top 64, and those players will begin match play Wednesday.

Admission to the tournament is free. Tee times Tuesday begin at 7:30 a.m.
