Pak, the first woman in 58 years to make the two-round cut in a men's golf tournament, shot a bogey-free third round and moved to 1-under 215, seven strokes behind leader Chang Ik-je.
Pak entered Saturday tied for 29th after shooting 72 and 74. She is the latest in a series of female golfers to play against men this year, but the first to make the cut since Babe Zaharias played in three PGA Tour events in 1945 and made the 36-hole cut at all.
In May, Annika Sorenstam became the first woman since Zaharias to play on the PGA Tour but missed the cut at the Colonial.
Connecticut club pro Suzy Whaley (PGA Tour), 13-year-old amateur Michelle Wie (Nationwide, Canadian tours) and Laura Davies (Asian PGA Tour) failed to make the cut at other tournaments. Jan Stephenson played on the Champions Tour, which has no 36-hole cut, and tied for last.
