The 25-year-old, aiming to become only the fifth woman in history to claim three majors in a calendar year, is one shot clear of Japan's Shiho Kuwaki. Earlier this month, Ryu claimed her second major in the space of two weeks at the Evian Championship, and her remarkable major form has continued at the Open. Despite being three over for the day through five holes, she sank five birdies to shoot two under par and build on her opening-round score of 66. "The last hole is so important as it is always good for tomorrow, I always want to make a good score on the last hole," Ryu told BBC Sport. "I just stayed patient after that [the tough start] and I made some birdies to finish under par. I am so happy now."
