Ireland’s Leona Maguire finished two shots behind winner Lydia Ko at the LPGA Tour championship in Florida.
New Zealand’s Ko birdied twice in the final three holes to finish 17 under and claim the $2 million prize.
Maguire, 27, couldn’t repeat his stunning third-round 63 and had to settle for second place after hitting a level par 72 in the final round.
England’s Georgia Hall hit 67 in their fourth round to finish tied for fourth, five shots behind KO.
“It’s been an amazing week, a really good way to end the season,” Maguire said.
“If you had offered me the second at the start of the week, I would have grabbed it with both hands.
“It would have been nice to play a bit better today, but the wind was strong and it was cold. The bowling was tricky.
“I didn’t play the way I played yesterday, but I grafted really well. I had some really big ups and downs to keep me and keep some pressure on Lydia, but she played really strong all day and a deserving winner.”
Maguire was level with Ko overnight after his superb under-63 nine on Saturday, but windy conditions made it difficult to score low for the final round.
Ko bogeyed the first to put Maguire in the lead, but the New Zealander fired back with two birdies on the third and eighth to hold a one-shot advantage before the back nine, as Maguire’s only birdie on the fourth was immediately canceled by a bug.
Both challengers bogeyed on the 14th, but Ko caught back-to-back shots on the 16th and 17th – which Maguire also birdied – and the 25-year-old held on to clinch the biggest first prize in women’s golf.
