Knight and Szokol closed with a five-under 65 in better-ball play at Midland Country Club on Saturday.

They finished at 23-under, following a better-ball 61 in the second round on Thursday with an alternate-shot 62 on Saturday to take a three-stroke lead into the final round.

Finland's Castren and Tan, of Malaysia, carded a 63 to finish a shot back and repeat their second-place finish of last year.

The 26-year-old Knight also won the 2019 Ascendant LPGA, while for Szokol the win brings a first title on the Tour.

The U.S duo tied for fourth last year after missing the cut in 2021.

"I've been in contention a few times, and I really haven't handled the pressure," Knight said. "Kind of let it get to me a little bit.

"We joked at the beginning of the week. We were, 'Why not win?'.

"I couldn't have asked for anything better than to get the win with her."

Szokol also acknowledged the pressure of leading from the front.

"There was a lot of pressure. Starting the day with a three-shot lead was a great thing, but everyone was chasing us," she said.

"Matilda and Kelly were playing great and started off really well. Definitely some pressure there. Cheyenne made some amazing putts coming in."

The teams of Celine Boutier-Yuka Saso (62), Jodi Ewart Shadoff-Emma Talley (63) and Celine Borge-Polly Mack (63) tied for third at 20-under.

Australia's Sarah Kemp and her playing partner Alena Sharp, of Canada, carded an equal-best final-round 60 – 10-under for the day – to finish in eighth place at 16-under overall.

Karis Davidson, playing with Ecuador's Daniela Darquea, was three shots further back in joint 13th place after a last-day 62, while all-Australian pair Hannah Green and Su Oh finished tied for 26th at nine-under.
