Lydia Ko is within striking distance of the top through two rounds of the ANA Inspiration LPGA tournament in California this weekend.
Ko is tied-sixth and five under par after a topsy-turvy second round overnight.
Entering the day two-under, Ko shot an early birdie on the second hole, before back-to-back bogeys on the sixth and seventh lost her early momentum.
Another bogey on the tenth dropped Ko to just one-under, but she made up for it immediately, firing home an eagle and a birdie on the following two holes.
A strong finish to the back-nine saw Ko finish five-under and stay within touching distance of the leader, Patty Tanatavakit of Thailand, who finished the second round nine-under.
Ko is in a six-way tie for sixth alongside Germany's Sophia Popov, England's Georgia Hall, and the South Korean trio of Inbee Park, Mirim Lee and Jin Young Ko.
