Stephanie Meadow is within six shots of the lead ahead of the final round at the JTBC Classic.
The Antrim native carded a 67 in Saturday's third round at the Aviara Golf Club in California to move into a tie for 11th, while Leona Maguire is two shots further back on six under after a 71, joint-20th on the leaderboard.
Maguire's 2021 Solheim Cup team-mate Nanna Koerstz Madsen, fresh from joining the Cavan native in becoming an LPGA Tour event winner earlier this month, leads the way on 14 under after carding a 69.
South Korea's Na-Rin An is three shots behind the Dane on 11 under, with the trio of Pajaree Anannarukarn of Thailand, Canada's Maude-Aimee Leblanc and Korean Jin-Young Ko tied for third on 10 under.
Meadow had eight birdies during her third round, with the only setbacks coming with bogeys on the 11th and the 18th.
Maguire, meanwhile, birdied the seventh and 11th with just one bogey on four.
At the top of the leaderboard, Madsen bounced back from a bogey and double bogey at the seventh and eighth holes.
She sandwiched six birdies around that brief three-over stretch, including two at the ninth and 10th holes to get back on track.
"It does tell me that I've come a long way," Madsen said.
"Normally I probably would've freaked out after that (hole) eight. I was not happy with my double bogey on eight, but I knew there was a lot of chances out there on the back nine as well. So I just got to continue doing what I was doing. I was still hitting good shots."
Madsen is looking for her second LPGA Tour victory after breaking through for her first at the Honda LPGA Thailand earlier this month.
