Christine Song expanded her lead at LPGA Q-school on Friday, taking a five-shot lead into the final two rounds.
Song shot her second consecutive 2-under 70 to go a handful ahead of Jennie Lee.
Jacqui Concolino and amateur Stephanie Kono are seven behind Song on 3 under through 54 holes of the 90-hole event at LPGA International.
Scoring conditions continued to be difficult for the field, leaving just five players under par through the middle round of the tournament.
Though the LPGA is not certain of the specific number of cards awarded at the end of play Sunday, the top 40 players are assured of some status. Among those inside that watermark are Jean Reynolds, Mariajo Uribe, Meredith Duncan, Minea Blomqvist, 17-year-old Ginger Howard and Big Break alums Mallory Blackwelder and Lili Alvarez.
Two-time U.S. Women's Amateur winner Danielle Kang is 3 over and tied for 22nd. Kimberly Kim, the youngest to win the U.S. Women's Am, is 137th.
Despite the difficulty in scoring, 26 players broke par on Friday – an increase of 16 players over Thursday's play.
A cut will be made to the low 70 and ties after Saturday's fourth round.
