Nelly Korda will take a one-shot lead into the final round of the Tournament of Champions -- the LPGA's 2022 season opening event.

But the world No.1 won't be able to rest easy with another three major champions among the top five in Florida after 54 holes.

Korda, a five-time winner in 2021 (including an Olympic gold medal), limited her mistakes on Saturday in challenging, chilly conditions at Lake Nona Golf and Country Club for a 3-under 69 to get to 13-under 203.

Danielle Kang, the runner-up at this tournament a year ago, and Mexico's Gaby Lopez, the 2020 champion, each went bogey-free in matching Korda's 69, and will begin the final round one shot back.

Canada's Brooke Henderson and Japan's Yuka Saso matched the day's low score of 68 and will begin Sunday's play two and three strokes off the pace, respectively.

Kang, Henderson and Saso all have won major championships.

Korda, who is seeking her eighth career LPGA title, on Saturday, she played alongside a former No.1 player, Annika Sorenstam, who won 72 times on the LPGA and leads the celebrity field.

"I don't think anyone is ever really comfortable sleeping on a lead in a sense, but I'm just going to see how I can grow from this opportunity, try to take my best golf into tomorrow, and see how it goes," Korda said.

Kang held the lead briefly on the back nine and has made only one bogey in three rounds.

"There is still a lot of progress to be made," the American, who is coming off a rare winless season, said.

The field this week comprises 29 winners of events in the past three LPGA seasons -- competing alongside 50 celebrities.

Australian stars Minjee Lee and Hannah Green were eligible but have both elected to skip the event in Florida.

Sorenstam, who won last summer's US Women's Senior Open and is a member at Lake Nona, leads the celebrity division, which uses a modified stableford scoring system, by two points from former MLB pitcher Derek Lowe.

The winner among the celebrities will earn $100,000 ($A140,000).

The LPGA champion will earn $225,000 ($A315,000).
