South Korean Lee Ji Hee sank a superb 24-foot birdie putt on the first playoff hole to beat Taiwan's Wei Yun-jye and clinch victory in the Suntory Ladies Open on Sunday.

After letting her four-stroke overnight advantage slip through her hands, the 24-year-old from Seoul held her nerve by rolling in the decisive birdie on the par-4 18th hole at the Japan Memorial Golf Club.
