At six under through 13, Wright was in great shape to lead herself, but she could not make another birdie and was one over for her remaining five holes.

Yani Tseng, the 2010 champion, was third on four under, a shot ahead of a group of seven players on three under which included England’s Jodi Ewart.

Ewart was bogey-free for her round and birdied the ninth, 11th and 16th holes.

Defending champion Stacy Lewis had a day to forget, as she ended in a share of 60th on two over, the same mark as Scotland’s Catriona Matthew. The only other Scot in the field, Janice Moodie, was a shot better off after a 73 that included one birdie and two bogeys.
