Nelly Korda won her second LPGA Tour event of 2024 – and 10th of her career – with a play-off victory over Ryann O’Toole.
The American pair finished on nine under par at the Seri Pak Championship at Palos Verdes in California to force a decider.
And it was Korda who sealed it on the first play-off hole with a birdie.
The win was enough to send the 25-year-old Olympic champion back to the world number one spot.
Korda last played seven weeks ago, when she beat Lydia Ko – also in a play-off – to win the Drive On Championship.
She looked like easing to victory when an eagle at the 14th saw her lead by three on a windy course.
But back-to-back bogeys saw her finish with a two-under-par 69 while O’Toole’s five-under 66 was the lowest round of the day and left them both on nine under.
“Today was just really tough. But I think that’s also the beauty of the game,” said Korda, 25.
“It’s fun to play in these conditions and kind of be a little bit more artistic out here.”
Australian rookie Gabriela Ruffels – a former professional tennis player – finished a shot behind the leaders, alongside American Alison Lee.
Scotland’s Gemma Dryburgh and England’s Charley Hull were a further three shots behind, both ending on five under.
