Australia's Hannah Green made a 30-foot birdie putt on the final hole to win the HSBC Women's World Championship.
The 27-year-old shot a 5-under 67 on Sunday, including three birdies in her final three holes, to overtake France's Celine Boutier.
Green started the final day at Singapore's Sentosa Golf Club in second place behind Japan's Ayaka Furue.
Although he hit a bogey on the 10th hole, he made a number of birdies in the second half to finish at 13 under, clinching his fourth win on the LPGA Tour.
Boutier shot a final-round 67 to match Green at 12 under, but Furue suffered a double bogey on the final hole and had to settle for a share of eighth place at 7 under.
Green's winning putt on the 18th clinched his first victory since last year's JM Eagle LA Championship, sparking loud cheers.
“I knew I had to at least make a birdie at the end to win by one. As soon as that putt went in, I thought, 'Oh my god, I won,'” Green said.
“The best moments don't always come and golf is sometimes a learning sport, so you have to overcome the best moments.
“The first time I played in 2021, I almost won, and I remember three-putting on the 17th and then three-putting again on the 18th and losing.
“I am very happy to be able to hold this trophy now.
“Celine played well today, but in the end she didn't get the trophy. But she should be proud of how she played under this pressure.”
