Megan Khang took a share of the LPGA Classic lead on Friday in her first event as a Tour member.
The 18-year-old eagled the fourth and found another four birdies en route to a 5-under 68 in difficult windy conditions in the Bahamas.
She now shares a half-way lead with Charley Hull and Haru Nomura at 8-under at the top of the leaderboard.
Defending champion Sei Young Kim is ominously close just a shot back, though, alongside Anna Nordqvist, Catriona Matthew and Min Seo Kwak.
However, it was not a good day for Michelle Wie, who missed the cut by a single stroke after being stung by a bee on the hand during the opening day.
Leaderboard: -8 M Khang (US), H Nomura (Jpn), C Hull (Eng); -7 S Young Kim (Kor), M Seo Kwok (Kor), C Matthew (Sco), A Nordqvist (Swe), -6 P Creamer (US)
