Ai Miyazato surrendered her share of the lead after carding a 1-under-par 71 in the third round of the ANA Inspiration in Rancho Mirage, California, on Saturday.
The former world No. 1 had two birdies and a bogey at Mission Hills Country Club but remained in title contention tied for fifth at 8-under 208, two shots behind overnight co-leader Lexi Thompson of the United States.
Thompson, who won this tournament in 2014, shot a 69 and closed out her round one stroke ahead of a three-way second-place tie between world No. 1 Lydia Ko of New Zealand, Thailand's Ariya Jutanugarn and South Korea's Chun In-gee.
