EVIAN-LES-BAINS, France Celine Boutier posted a 2-under 69 in the second round of the Evian Championship to move to 7 under overall, giving her a one-shot lead on Friday.

Surprise overnight leader Paula Reto dropped down the leaderboard after a 4-over 75.

The 29-year-old Boutier, who was two shots back of Reto overnight, is looking to become the first Frenchwoman to win the tournament, which became a major in 2013.

Its really great to feel the support from the fans when you play some good shots and some good putts go in, Boutier said. This kind of support used to put me under pressure in the past, and I didnt cope well with it, but this year Im trying to stay very relaxed.

Her solid round kept her narrowly ahead of Thailands Patty Tavatanakit, who carded 67, and Japans Yuka Saso (69), in a tie for second.

They are one shot ahead of Nasa Hataoka of Japan (67), Mexicos Gaby Lopez (68) and American Alison Lee (71).

Reto struggled badly on the back nine, with a double bogey on the 12th hole followed by three bogeys over the next four holes.

The 33-year-old South African ended the day in a tie for eighth at 3 under overall along with defending champion Brooke Henderson of Canada, who finished with a 70.

Boutier was level with 2015 champion Lydia Ko of New Zealand overnight, but Ko drifted way back into a tie for 22nd after a dismal round of 76 at the Evian Resort Golf Club.
