Stephanie Meadow rallied on day two at the Palos Verde Championship to make the cut but Leona Maguire will miss the weekend rounds.
Both Irish contenders were off the early pace after Thursday's opening round in California.
Meadow was able to climb up the leaderboard after a 68 in Friday's second round to move to within eight shots of leader Hannah Green of Australia.
The Antrim native is on one-under, currently tied for 30th after that round which featured five birdies.
Maguire, meanwhile, followed her opening 74 with the same score on Friday to miss the cut by four shots on six-over.
At the top of the leaderboard, Green, coming off a runner-up finish last week at the LA Open, is in position to improve on that result just down the road this week.
Green holds a three-shot lead at the midpoint at the Palos Verdes Estates course.
Thanks to a six-under-par 66 in the second round, Green is at nine-under.
First-round leader and fellow Australian Minjee Lee fell into a tie for second at six-under after a 73 on Friday.
Megan Khang (second-round 69), New Zealand's Lydia Ko (67) and South Korea's Jin Young Ko (72) are also at three-under.
Annie Park (69), Jennifer Chang (72) and Canada's Maude-Aimee Leblanc (68) share sixth place at five-under. Robynn Ree (68), Marina Alex (68), Andrea Lee (68), South Korea's Inbee Park (67) and Denmark's Nanna Koerstz Madsen (69) are tied for ninth at four-under.
Green, 25, owns two career LPGA wins, both in 2019. She finished five strokes behind Japan's Nasa Hataoka last week at the LA Open.
On Friday, she began her round with three consecutive birdies, then added two more at the sixth and seventh. She bogeyed 12 and 13 before responding with birdies at 14 and 16.
