Australia's Lee, one of seven majors champions topping the leaderboard, is tied for fifth at 13-under and trails defending champion Nelly Korda by five strokes.

Korda made a 22-foot eagle putt on the par-5 18th for a six-under 66.

Making her second start since returning from a four-month break because of a blood clot in her left arm, Korda also eagled the par-5 8th and had three birdies and a bogey on Saturday. She was at 18-under 198 at Blythefield Country Club.

"I'm just happy to be out there playing again," the 23-year-old said.

"I'm in contention, but, again, I've been in this position before. Thankfully, I can lean on that."

The second-ranked Korda tied for eighth two weeks ago in the U.S. Women's Open in her first event since early February. She also is the defending champion next week in the KPMG Women's PGA at Congressional.

"I knew that I had enough practice under my belt and it was just more of like, 'Can I put that into tournament golf kind of play,'" Korda added.

"So far, I've played pretty well and hopefully I can continue."

Jennifer Kupcho, two strokes ahead of playing partner Korda entering the day, had a 69 to drop a shot back.

"I wasn't playing as well as I thought I should," World No.16 Kupcho said.

"I think after a little bit of a rough start, missed a couple fairways, I kind of set a goal for myself to shoot three under and I did do that. So glad to have done that."

Canada's Brooke Henderson, the ShopRite LPGA Classic winner last Sunday in New Jersey and 2017 and 2019 champion at Blythefield, is third at 15-under after a 67.

Lexi Thompson, the 2015 winner, had a 68 to get to 14-under while Kiwi Lydia Ko (65) is one back.
