Leona Maguire fell short in her bid to claim a record $2m purse at the CME Group Tour Championship in Florida as she finished runner-up to Lydia Ko.
Maguire went into the final round as the joint-leader with Ko after shooting a sensational nine-under 63 on Saturday.
She couldn't scale those heights on Sunday, despite staying in touch all the way she led only briefly in the early stages, and carded a level-par 72 to sign off on 15-under-par overall as Ko snuck it by two shots.
It still represents a terrific showing from Maguire who collects $550,000 for the second-placed finish.
"It was an incredible week," she said. "A really great way to finish off the season. If you had offered me second at the start of the week, I would have grabbed it with both hands.
"It would have been nice to play a little bit better today, but it was really tough out there today. The wind was strong. It was cold. Pins were tricky."
Meanwhile, Ko pockets the largest pay-day in the history of women's golf - a cheque for $2m that is $200,000 more than the 2022 US Women's Open champion won and $1.25m more than what the season's first major, the Chevron Championship, paid its winner.
"I felt calmer than I thought I would be," said Ko at the presentation ceremony.
"There was a lot of things on the line today. I really wanted to play the best golf I can.
"There were so many big names chasing Leona and I. I knew it would be a tough battle, especially with how tough the conditions were as well, but I just focused on my game.
"I just wanted to make my share of birdies."
