Australia's Hannah Green remains in contention to win the LPGA event in Ohio after carding a third-round five-under 66.
The 2019 US Women's PGA Championship winner is joint-4th, trailing 19-year-old Lucy Li who recovered from a sluggish start for a four-under 67 and a one-shot lead in the Dana Open.
Li was two over through seven holes and quickly fading from the picture at Highland Meadows when she responded with five birdies over the next 10 holes to regain the lead and set up a final round filled with possibilities.
Lexi Thompson ran off three straight birdies late in the round and shot 65, along with Germany's Caroline Masson to be one stroke behind.
Seven other players, including Green and two-time tournament winner Lydia Ko who had the low round of the day at 64, were three shots back.
"I was probably a little nervous. It wasn't anything crazy, but haven't felt nervous in a long time," Li said.
"Actually making those bogeys might have helped a little, just getting that out of the way and knowing that I could just freewheel it out there a little."
Thompson, 27, was just 12 when she first qualified for the US Women's Open at Pine Needles. Seven years later, Li broke her record when she qualified for the 2014 Women's Open at Pinehurst No.2.
"It'll be great," Thompson said ahead of playing the final round with Li.
"I played with her a little bit -- not so much out here. But I think everybody knows how amazing of a player she is. Just speaks wonders to the amount of work that she's put into her game, just the amount of talent she has."
Also in the mix is Japan's Nasa Hataoka, the defending champion, who had a 67 and was part of the big group at 11 under.
Equally daunting is Ko, who won on this course in 2014 and 2016.
The Kiwi started on the back nine and after a bogey on the 11th, she holed out for eagle on No.12 and ran off a series of birdies.
"They moved the tee forward a little on 12 and I was just, 'Hit driver off the tee.' I only hit a gap wedge," she said.
"It's not the greatest finish ... I did what I needed to do."
For Thompson, the women's world No.7, it's another chance to end more than three years without winning.
"I go into every tournament wanting to win. Yeah, it has not worked out the way I want it to in a few events, but that's golf," Thompson said.
Australia's world No.3 Minjee Lee, who leads the Race to the CME Globe, shot a 70 to be in a tie for 46th at four under while compatriot Steph Kyriacou (67) is six under.
