PRATTVILLE, Ala. (AP) -- Defending champion Lexi Thompson shot a 3-under 69 on Friday to take a one-stroke lead into weekend play in the Navistar LPGA Classic.
The 17-year-old Thompson had a 12-under 132 total on the links-style Senator course at the Robert Trent Jones Golf Trail's Capitol Hill complex. She matched the tournament record Thursday with a career-best 63.
Last year, Thompson became the youngest champion in LPGA Tour history at age 16, winning by five strokes. Fifteen-year-old amateur Lydia Ko broke the record last month in the Canadian Women's Open.
Mindy Kim and Mi Jung Hur were a stroke back. They played in the same group and each shot 65.
Kim and Hur also missed late chances to tie Thompson. Hur missed a 3-foot birdie putt on the par-5 eighth, their 17th hole of the day, and Kim missed a 6-footer on the par-4 ninth.
Dori Carter was two strokes back at 10 under along with Hee Young Park and Lizette Salas. Carter had a 67, and Park and Salas shot 69.
Top-ranked Yani Tseng was 3 under after a 70. Michelle Wie missed the cut by a stroke, shooting a 73 to finish at even par.
