Jin-Young Ko of South Korea and Teresa Lu of Taiwan shot 3-under 69s Saturday to share the lead after the third round of the Women's British Open, with both players chasing a first major title.
Second-round leader Suzann Pettersen is a stroke behind their 8-under total of 208 after shooting 72 on a day of changeable weather on the Ailsa links.
Chasing victory to complete a career Grand Slam, top-ranked Inbee Park (69) is in a three-way tie for fifth place, with world No. 2 Lydia Ko (72) and Minjee Lee (70).
The 20-year-old Jin-Young Ko is the surprise of the tournament. She is playing in her first major, has never played links golf, and has hired a temporary caddie for the event. They met for the first time on Tuesday.
