Kim Hyo-joo holds the overnight ahead of the final round of the Evian Championship despite failing to make par for the second straight day.
The South Korean teenager had set a record for the lowest round in a LPGA Tour major with a score of 61 on the opening day, but could only card a one-over round of 72 on Saturday - replicating her performance from Friday.
But, with no player in the top five posting a score in the 60s, the 19-year-old's round was enough to see her move to the top of the leaderboard at eight under par for the final major of the year in France.
Kim goes into the lead primarily as a consequence of a disappointing showing from American Brittany Lincicome.
Lincicome had led at the midway point following a six-under-par round of 65 on day two, however, she could not carry that momentum into the second half of the event, shooting a six-over 77 to slip to a four-way tie for sixth at four under.
The 28-year-old's day was encapsulated by a triple bogey at the par-five seventh, yet despite her slip-up, Lincicome remains confident she can recover and claim the title.
"Just looking at the leaderboard obviously one player is doing really, really well, and then there are a couple others that are fairly close to me," Lincicome said.
"If I can shoot what I shot yesterday or the day before that tomorrow, I feel like it should put me back in the hunt."
Australian Karrie Webb is a shot behind Kim following a one-under round of 70, while Hur Mi-jung is a stroke further back in the third.
Sweden's Anna Nordqvist and Colombian Mariajo Uribe are in a tie for fourth but the performance of the day came from Choi Na-yeon, whose four-under 67 represented the highest score of the round to put her into the tie for sixth.
