WILMINGTON, Del. -- Japan's Chiharu Yamaguchi fired a bogey-free 4-under-par 67 to grab a tie for second place, one shot off the pace in the first round of the LPGA Championship on Thursday.

The fifth-year pro rolled in four birdies to stand in a three-way tie for second with Gloria Park of South Korea and England's Karen Stupples at the Dupont Country Club while Jennifer Rosales of the Philippines took sole possession of the lead with a bogey-free 66.

Defending champion Annika Sorenstam was in another group of three tied for fifth on 68 at the event, which is the second women's major of the season.
