Korda finished with a 14-under 196 to earn a one-stroke victory over Lexi Thompson (66), while Allisen Corpuz (69) finished third, three shots off the lead.
LPGA Tour rookie Corpuz had a one-shot lead through two rounds after she opened with consecutive 65s.
The tournament was shortened from 72 to 54 holes after Tropical Storm Nicole forced Pelican Golf Club to stay closed on Thursday.
Korda earned her eighth career LPGA victory and her first since winning the same tournament last November when she finished at 17-under and won in a four-player play-off that included Thompson.
Korda is projected to return to No.1 in the world rankings. She had to battle through a difficult 2022, which included recovering from a blood clot in a vein in her left arm.
“Honestly amazing; it’s been a tough year,” Korda said on the Golf Channel broadcast.
“Lots of ups and lots of downs … but kept my head high and worked really hard during my few weeks off, and feel really good to be back out.” – Nelly Korda.
“Lots of ups and lots of downs. Missed two cuts in Arkansas and Dallas, but kept my head high and worked really hard during my few weeks off, and feel really good to be back out.”
Korda finished off the victory despite a bogey on the 18th hole. She was three-under on the front nine and five-under on her round through 13 holes. She took command with birdies at 16 and 17 to earn the victory.
Corpuz’s chances started to slip away when she went one-over on the front nine after eight pars and a bogey at the 8th.
Hannah Green (65) – the only Australian to make the cut – finished in a three-way tie for fourth alongside Morgane Metraux of Switzerland (64) and Mexico’s Gaby Lopez (67).
The LPGA moves on to next week’s season-ending $US7 million CME Group Tour Championship at Naples, Florida.
“I’m most excited about spending the night in my own bed tonight, and then I’ll do some laundry and drive down (Monday) hopefully fresh,” Korda said.
“But right now I’m just going to soak this all up with my family, and next week is a new week, so I’m going to try to get back in shape and see how it goes.”
