Yealimi Noh has taken the lead at the AIG Women's Open after Haeran Ryu's collapse, with Lottie Woad and Charley Hull still in contention. Ryu had been on course for a third consecutive major victory, but a run of five bogeys in eight holes saw her drop to a three-over 74. Noh, who started the day two shots behind, carded a two-under 69 to open up a three-shot lead. The American will head into the final day on seven under, chasing her first major title, while Ryu is tied for second alongside Jeeno Thitkul, Lucy Li, and Shiho Kuwaki.

Woad is four shots back, with Hull a further stroke behind, and both English players are poised to make a final-day charge. World No 1 Nelly Korda is eight shots adrift after a double-bogey at the final hole. Ryu had started strongly, with back-to-back birdies from the third hole, but her round began to unravel with a wayward drive at the seventh. She eventually scrambled a bogey, but dropped another shot at the next hole.

Noh, meanwhile, posted three consecutive birdies from the ninth to join Ryu at the top of the leaderboard. Ryu's struggles continued as she bogeyed the 12th and 14th, while Kuwaki failed to save par at the 15th, allowing Noh to open up a two-shot cushion. Noh is now looking to become the first American to win the AIG Women's Open as her maiden major since Mo Martin in 2014. 'It was a little bit of a rocky start, but my putting was solid and my shots too,' Noh said.

'I just settled into a better routine and focused on my tempo on the back nine. I'm just happy to be in this position and ready to go again.' Woad can overtake Chiara Tamburlini on the Ladies European Tour list with a solo third finish or better, and the world No 5 is well-placed to challenge for a maiden major title.

'It's a good position to be in,' Woad said. 'I should be a few back.

I'll stick to my game plan and see what happens. I felt a bit better on the greens today and I scrambled pretty well to get around.' Hull fell 10 shots behind after a poor start, but rebounded with back-to-back birdies and then salvaged a level-par 71 with successive birdies from the 15th. 'I'm pretty proud as the first six holes I played like a 10-handicapper, I felt,' Hull said. 'I missed three putts I should have holed from five feet and in, which would have kept me level par instead of being three over.

I had a bit of a bounce back and I was pretty happy with the way I finished.'
