INCHEON, South Korea (AP) -- Lydia Ko made an 18-foot birdie putt on the final hole for a 7-under 65 and a one-stroke lead Friday in the LPGA KEB Hana Bank Championship.
The 18-year-old South Korean-born New Zealander moved into position to regain the No. 1 spot in the world from South Korean star Inbee Park, one of her playing partners Friday. Ko would take the top spot with a victory and also could move up under other scenarios.
Ko had a 10-under 134 total on Sky 72's Ocean Course.
Park was tied for 25th at 3 under after a 72.
