EVIAN-LES-BAINS, France — South Koreans In Gee Chun and Sung Hyun Park shot 8-under 63 on Thursday to share the first-round lead in the Evian Championship, the last of the LPGA Tour’s five majors.

Top-ranked Lydia Ko’s bid to defend her title — and win a third career major by the age of 19 — got off to a rocky start with a 70.

“It was tricky for me because on the back nine I was not hitting fairways,” the New Zealander said. “Hopefully, I’ll be able to hit some fairways tomorrow.”

Chun, the 2015 U.S. Women’s Open champion, said she felt nervous after missing the cut here last year but hardly let it show.

“I could see the putting lines and I was good rolling the ball on those lines,” she said. “The greens are getting softer this year.”

While Ko’s play was patchy, with a bogey and only two birdies, second-ranked Ariya Jutanugarn of Thailand had a triple bogey in a 73.

American Annie Park had an eagle and five birdies to match China’s Shanshan Feng at 64. American Angela Stanford had a 65, and South Koreans So Yeon Ryu and Eun-Hee Ji shot 66.
