Australia's Minjee Lee is steadily climbing up the leaderboard despite some late blunders in the second round of the LPGA's Kia Classic.
The world No.10 jumped to joint sixth after posting a three-under 69 on Friday that left her six shots behind leader Inbee Park.
Lee, who went around in even par in the opening round, hit top form early in the round. She birdied the second, followed that up with another pair on 6 and 7 before eagling the par-five 8th.
The West Australian then found trouble on the par-five 10th, taking seven before dropping another on 12. She then fought back with a birdie on the par-three 14th to remain in the mix.
Park clung on to her overnight one-shot lead by matching Lee's 3-under 69 for a two-round total of 9-under 155.
She leads from Sophia Popov, who shot 68 for the second straight day, with Mel Reid (70) a shot further behind.
Park, the 20-time Tour winner with seven major titles, had four birdies and got to 10 under before her only bogey, on the par-4 seventh - her 16th.
"I hit good shots, and it's just weird on these greens, because I hit the shots really close and I don't make the birdie putt, but I kind of hit it to 15, 20 feet and I make those birdie putts," she said.
"The holes I made today is pretty much I made probably 10- to 20-footers. But coming in last three holes I missed probably inside five, six feet. So it's just greens that really need patience.
"I played good throughout the day today, struck the ball well, hit a lot of greens, gave myself a lot of opportunities, so happy with the round."
Meanwhile, Michelle Wie West missed the cut in her first tournament in nearly two years.
Wie West shot a two-over 74, an improvement of seven strokes from her opening-round 81 to finish at 11-over 155.
She had two birdies, two bogeys and a double bogey.
