Rank outsider Hana Wakimoto stayed two shots clear at the halfway stage of the LPGA Japan Classic on Friday as Thailand's Ariya Jutanugarn moved up to tied second on the leaderboard.
Japan's world number 236 Wakimoto carded a four-under-par 68 for 13-under overall at Seta Golf Course.

She has had two top-10 finishes this year on the Japanese tour, which she joined in 2018.
Jutanugarn, a two-time major winner, was 11-under after two rounds along with American Yealimi Noh.
Jutanugarn shot a six-under 66 in a bogey-free round that featured six birdies.
South Korea's Ko Jin-young shot 70, leaving her in tied fifth at nine-under.
The former world No 1 and two-time major winner made three birdies but blotted her copybook with a bogey on the 17th hole.

Saso was tied with Japan's Ayaka Furue, who won the Evian Championship in July for her first major, and South Korea's Ryu Hae-ran.
Australia's Minjee Lee tumbled down the leaderboard to a share of 52nd after a 75.
