Stephanie Meadow sat well down the leaderboard after an opening one-over par round at the Portland Classic.
Meadow's 73 left her 10 shots off clubhouse leader Perrine Delacour with a number of players still on the course late on Thursday night.
Starting on the 10th, Meadow made a perfect start with an opening birdie with eight straight pars following to close out her opening nine.
Bogeys at the first, fifth and seventh saw Meadow fall down the rankings, although a birdie on her penultimate hole helped.
Delacour's bogey-free round beat out a number of players who also went low at Columbia Edgewater Country Club. Gina Kim is in second with an 8-under 64, and world No. 2 Nelly Korda is tied for third at 7-under 65 with Sweden's Linn Grant and Germany's Olivia Cowan.
Delacour birdied the par-4 first hole before starting a run of five straight birdies at the par-4 third. After six straight pars, she made a late push with birdies at Nos. 14, 15 and 17.
"I didn't know what was my score at some point," Delacour said. "When you're in that zone, you don't realize your score and you're... not scared to (do)anything. You go to every pin and you know it's going to be fine."
Kim had eight birdies without a bogey to post her lowest round in two years on tour. Kim has missed nine cuts in her past 10 starts.
"It's been tough this whole season, and I kept grinding through it," Kim said. "I kept believing in myself that maybe, you know, one of these days I'm going to be able to catch a good round like this. So it's nice to hit the ground running out here."
Korda, 25, began her round on the back nine and made four birdies on each side, with just one bogey sullying her card at the par-4 18th.
#"I think the golf course is just in general playing a little softer than it was last year," said Korda, who hasn't won on tour since November. "I just knew with the amount of rain we were getting throughout the day that I could just be a little bit more aggressive."
Grant, 24, won her first LPGA title in July at the Dana Open and stayed on top of her game by following that with a tie for 16th, a tie for 20th, a tie for11th and a tie for sixth. She had eight birdies and one bogey on Thursday.
