The West Australian shot a closing four-under 68 to reach 11 under but she was still six shots from local winner Ai Suzuki (67) and three behind South Korean Hyo Joo Kim (66).

It was World No.7 Lee's ninth top-10 finish of the season, following 12 of them in 2018.

The 23-year-old now joins the rest of the Tour's top 60 at the US$5 million Tour Championship in Florida from November 21-24.

FINAL LEADERBOARD

While Lee managed seven birdies against three bogies in the final round, overnight leader Suzuki went bogey-free.

Lee's countrywoman Hannah Green, a two-time winner in 2019, was tied 10th at eight under after a closing 72.
