World No. 1 Park In-bee failed to make the cut in the Airbus LPGA Classic in Mobile, Alabama on Friday.
Competing in her first tournament in three weeks, she finished 129th with six-over-150 in the second round.
Anna Nordqvist of Sweden finished top of the leaderboard after round three on Saturday with 16-under-200, while Stacy Lewis of the U.S. was in third place at 14-under. Korea's Ryu So-yeon and Ji Eun-hee were joint seventh at 12-under.
Lewis, the current world No. 2, can dethrone Park in the world rankings if she finishes in at least third place.
