Australian No.1 Minjee Lee is comfortably placed after the opening round of the Buick LPGA Shanghai tournament in China.
The West Australian is just two strokes off the early pace set by Thailand's world No.2 Ariya Jutanugarm, who shot a six-under 66 to hold a one stroke lead on Thursday.
Lee recorded six birdies in her four-under 68 to sit in a six-way tie for fourth, while compatriot Su Oh was a stroke further back after also breaking par of six holes.
Jutanugarn had six birdies - including three in a row - in a bogey-free round; Sei Young Kim of South Korea and American Danielle Kang of the United States were a shot back in second after 67s.
Australian's Sarah Jane Smith and Katherine Kirk will seek to improve on rounds on 74 on Friday.
The tournament is the second of five being played in South Korea, Japan, China, and Taiwan in the LPGA's annual Asian swing.
