ST. ANDREWS, Scotland, Aug. 2 (UPI) -- Lorena Ochoa shot a 6-under 67 Thursday over the Old Course to take a two-shot lead after one round of the Women's British Open Championship.
This marks the first time a women's event has been contested on the historic links of St. Andrews.
Ochoa, ranked No. 1 in the world, was out front of Louise Friberg and In-Bee Park, who shared second place after shooting 69s. The par at St. Andrews was changed from 72 to 73 this week by converting the difficult 17th hole to a par-5.
Ai Miyazato and Rebecca Hudson were at 70 while Annika Sorenstam, looking for her first victory since overcoming back problems earlier this year, opened with a 72. Defending champion Sherri Steinhauer also shot 72.
Michelle Wie, who has struggled this year with a wrist injury and high scores, fired a 73 and was tied for 21st.
