GRAND RAPIDS, Mich. (AP) Brooke Henderson shot an 8-under 63 on Thursday to top the star-packed leaderboard in the Meijer LPGA Classic.
The 19-year-old Canadian eagled the par-5 eighth hole and had six birdies in a bogey-free round at Blythefield. She won the major KPMG Women's PGA Championship last year and has three tour victories.
Major champions Lexi Thompson, Stacy Lewis and Shanshan Feng were a stroke back along with Jennifer Ha, Giulia Molinaro and Holly Clyburn. Lydia Ko, at No. 2 in the world after an 85-week run at the top, returned from a three-week layoff to top the group at 65.
New No. 1 Ariya Jutanugarn opened with a 69. She won the Manulife LPGA Classic on Sunday in Canada in a playoff with Thompson and In Gee Chun.
