Also the winner in the season-opening event in the Bahamas, Korda played the back nine in 6-under 30 to finish at 20-under 268 on The Crossings course at the Robert Trent Jones Golf Trail's Magnolia Grove complex, according to a report by ESPN.
"It feels amazing," Korda said. "I have not been playing well since I basically won in the Bahamas (in January), and still trying to work on the same swing thoughts that Grant (Price, her swing coach) and I have been working on, so for it to finally pay off here is really nice.
"I've been working really hard on my short game. I've actually been working with Paul Azinger a lot at home because he's also from Bradenton, Florida. With his input and Grant's input, it just takes a while for it to click and put my old driver back into play, and I just felt really comfortable."
Michelle Wie, 18-year-old Charley Hull and 44-year-old Catriona Matthew tied for third at 18 under. Wie and Hull shot 67, and Matthew had a 69.
Wie played alongside Korda and Hull.
"I love playing with Korda," Wie said. "It's also really great playing with Charley as well, too. You feel old but it was a lot of fun."
Wie, the winner last month in Hawaii, has seven top-10 finishes in 10 starts this year.
"I knew I needed a low score," Wie said. "I got hot starting on and just didn't quite get it together on the back nine, but still I shot 5 under today and there's really nothing I can do. I'm just really happy for Korda. I had a lot of fun playing with her and I knew I needed a low number and I just didn't hit it low enough."
Korda started the day three strokes behind 54-hole leader Nordqvist and managed only one birdie on the front nine.
"Yesterday was a little frustrating because I was always around the hole and same thing actually on the front nine, watching Michelle make putt after putt after putt and mine were just kind of missing," Korda said. "I was like, OK, it's time to drop now. Then they started dropping on the back nine. It was a really relaxed day, so I really enjoyed the walk."
Korda broke out of the tie with three other players by hitting a downhill birdie putt at the 14th hole, then took the lead for good with a 25-foot birdie on No. 15.
"That last putt broke really hard," Korda said. "I probably played it about a yard out and I was just trying to get it down there close and it went in. I have not played well since I won in the Bahamas but I've been working hard and it finally paid off here."
