PORTLAND, Ore. -- Ayako Uehara found momentum from par saves on her opening two holes and turned that into a 7-under 65 for a one-shot lead Thursday in the AmazingCre Portland Classic.
Hannah Green had a 66 despite a bogey on her final hole at Columbia Edgewater Country Club, with Nelly Korda in the group another shot behind.
In a year in which the LPGA Tour already has had eight first-time winners, Uehara would be a surprise. The 38-year-old from has been on tour for a decade, and her only three victories came on the Japan LPGA.
Add that to Uehara missing so much of the year with a lung condition that made it difficult to breathe. She was treated and declared fully healthy, but not until she missed six months, returning two weeks ago at the Dana Open in Ohio.
"This is my third tournament. I think I'm very excited about it and then glad to be out here," Uehara said.
Uehara saved par twice to start the round, and then made five birdies over the next seven holes. After her lone bogey on the par-3 13th, Uehara birdied three of the last four holes to grab the lead.
Korda, the No. 2 player in the women's world ranking, had a colorful front nine of only two pars. She followed a birdie with a double bogey on the par-4 sixth hole, and then responded with an eagle-birdie-birdie finish.
"Kind of up-and-down day, but ended on the good side," Korda said. "Overall, I played some solid golf. Maybe made a few stupid errors, but that's golf."
Korda is still looking for her first LPGA win of the year. She missed four months early in the year because of a blood clot in her left arm and has won on the Ladies European Tour. A victory would help her return to No. 1 in the world with Jin Young Ko, the defending champion in Portland, out for a month to rest her left wrist.
And it would help Korda to avoid the trees, a tall order on such a tree-lined course.
"It's such a beautiful golf course. So many big, tall trees," Korda said. "But they're very thick and they're very high. They also start very thick, like they're very low. So when you miss a fairway it's hard to get through the trees."
Joining her at 67 were former Women's British Open champion Hinako Shibuno and Caroline Inglis.
Brooke Henderson played in the afternoon and joined the group at 68.
Korda wasn't the only player with a colorful card. Hye-Jin Choi of South Korea signed a card that had a 1, 2, 3, 4, 5 and 6. The last one was a double bogey to finish her round of 70. She made her ace on the par-3 eighth hole.
