South Korea's Chun In-gee grabbed a two-shot lead at the Evian Championship by carding a five-under 66 in the second round at Haute Savoie.
Chun, who earned LPGA Tour membership by winning the US Women's Open in 2015, moved to a total of 13-under 129 after scoring six birdies and one bogey on a rainy day in France.
Her compatriot Park Sung-hyun, who shared the lead with Chun after Thursday's play, was tied second with China's Shanshan Feng. Park lost ground by hitting three bogeys in a disappointing round of 68.

World number one Lydia Ko of New Zealand returned a 68 but she was nine shots off the pace.
Sarah Jane Smith is the highest-placed Australian with a share of 13th-place on the leaderboard at four-under-par.
Rio Olympians Su Oh (-2) and Minjee Lee (-3) only just made the cut but Karrie Webb (+8) missed out after shooting a seven-over-par 78 in her second round.
