Anannarukarn and Noh share Evian lead

Anannarukarn, 22, shot a bogey-free round, while Noh, 19, hit an eagle and five birdies to share the lead.

Five players trail them on five under, while world number one Nelly Korda is nine off the lead after a round of 74.

Five bogeys, including a fresh-air shot out of a bunker, saw American Korda end on three over par in pursuit of her second major.

"I have never done that before, but sometimes it is tough when you start so well," said Noh.

Below the leaders, American Lauren Stephenson, Dane Emily Pedersen, Japan's Jeongeun Lee and Thailand's Atthaya Thitikul look well set, a shot off the lead and in contention before day two.

Just go out and enjoy it," said Thitikul after her round of 66.

Defending champion and world number two Ko Jin-young suffered a similarly tough round to Korda, also shooting five bogeys - a one-over-par 72 leaves the South Korean battling to make the cut.
