South Korea's Ina Yoon saw a five‑shot cushion evaporate as compatriot Haeran Ryu moved two strokes clear with a 68 in the third round of the Women’s PGA Championship. Yoon, after a spectacular 62 and a 69 to sit at 12‑under through the halfway mark, carded a 75, falling to 10‑under.

Ryu, 25, backed her 64 from day two with a front‑nine eagle and three birdies, limiting damage on the wind‑swept back nine to a single bogey. World number one Nelly Korda, eyeing a third major this year, posted a one‑under 71, remaining four strokes off the lead. Two‑time champion Brooke Henderson sits at 10‑under after a three‑under 68, staying within striking distance.

The tournament boasts a $13m purse, the largest in women’s golf history, with $1.95m awarded to the champion. With Sunday’s round set under brisk winds, Yoon must claw back, while Ryu aims to convert her lead into a maiden major. Korda and Henderson remain poised to force a playoff if the leader falters.

Both South Korean hopefuls entered the event ranked among the world’s top five, and Yoon’s collapse underscores the mental strain of major contention. A victory would lift her onto the elite club of major winners, while Ryu’s potential triumph could signal a shift toward a new Korean dominance on the LPGA Tour.
