Defending tournament champion Hannah Green and Cydney Clanton each fired 6-under 66s on Friday to claim the first-round lead of the Cambia Portland Classic in Portland, Ore.
Play was suspended once during the round for lightning in the area, and then halted for the day at 7:19 p.m. Twenty players will need to finish their first round on Saturday morning, before the second round begins.
Among those players was Yealimi Noh, who was in a five-way for third place, one shot behind the co-leaders. She has one hole left to play. The other four, who completed their rounds, were Mexico's Gaby Lopez, Amy Olson, Caroline Masson of Germany and Great Britain's Mel Reid.
Green birdied five of her first seven holes at Columbia Edgewater Country Club, and her only hiccup came on No. 18, when she finished with a bogey to fall back into a tie with Clanton.
Green hit 13 of 18 greens in regulation and cited that as room for improvement in the final two rounds of the tourney, which was shortened from four rounds to three because of the poor air quality from wildfires in the area.
"I missed quite a lot of greens compared to my score, so the only putt I really missed was the one on the last. ... That's what I hope that I can continue. I know they're a little bit bumpy this afternoon, so hopefully I can just keep rolling it well and they will actually drop."
Clanton's round was nearly the reverse of Green's. She also had just one bogey, but hers came on No. 4. Clanton then birdied seven of the remaining 14 holes.
"I hit the ball really well, but I've been hitting the ball really well, and the putter was finally hot. I finally made some putts. It's also nice to hit some really close and had a par-5 in two have a two-putt. So it was really nice to see the ball starting to go in the hole," she said.
Lopez, whose season includes a season-opening Diamond Resorts Tournament of Champions in early January, also bogeyed the fourth hole, and then ran off six birdies in eight holes starting at No. 7.
After finishing tied for 59th in her last three tournaments, Lopez saw a difference on Friday.
"Putting-wise, it feels a little different than last week. I've hit the ball really good the last couple weeks and haven't made lots of putts, but they dropped today."
