Yealimi Noh seized the third-round lead at the AIG Women's Open at Royal Lytham & St Annes, capitalizing on Haeran Ryu's collapse. Ryu, seeking a third straight major win, carded a three-over 74 with five bogeys in an erratic stretch, dropping from a four-shot lead to tied second. Noh fired a two-under 69 to open a three-shot advantage heading into the final day.

Lottie Woad and Charley Hull remain in contention, sitting four and five shots back respectively. World No. 1 Nelly Korda fell eight shots behind after a final-hole double-burden. The logjam at tied-second includes Jeeno Thitkul, Lucy Li, and Shiho Kuwaki.

Noh, chasing a maiden major, credited solid putting and improved tempo on the back nine. Woad praised her scrambling ability, while Hull bounced back from a rough start with late birdies. The final round begins Sunday at midday on Sky Sports Golf.
