Defending champion Lydia Ko started her bid for a third major golf title by the age of 19 at the Evian Championship early today, the final major of the season.
But it will be hard to match her performance last year, let alone improve on it.
She became the youngest major champion in LPGA history with her six-shot triumph, sinking a 4.5m birdie putt to close with a final-round 63 for an LPGA record low last round by a winner at a major.
"A lot of memories of walking down the 18th on that last day," Ko said before the opening round.
"It was so much more than I could have ever imagined."
Since then, the Kiwi has picked up five more Tour titles, including a second major at the ANA Inspiration in April. She also came back from the Rio Olympics with a silver medal, finishing behind South Korean Inbee Park.
Ko truly announced her arrival on the biggest stage as a 16-year-old when she finished second at the Evian in 2013 - the year it became the fifth major in women's golf. Tipped as a future great in her mid-teens, she was already the youngest champion on the Tour after winning the 2012 Canadian Women's Open.
There has been no stopping her, and last year, she became the youngest woman or man to be ranked No1.
As well as clinching a third major, Ko has another target in mind. She hopes to win the third edition of the Rolex Annika Major Award, which rewards the player with the best combined record at all five majors. It is named after 10-time major winner Annika Sorenstam.
"It would mean so much," Ko said. "Without players like her, there might not be a Tour like it is today."
Also in contention this year are women's PGA champion Brooke Henderson, US Open winner Brittany Lang and British Open champion Ariya Jutanugarn.
Ko and the 20-year-old Jutanugarn will clinch the trophy with a win. They are also competing for the Rolex Player of the Year award, which is shaping as a two-way race between them.
Ko is just five points ahead of Jutanugarn, while Henderson sits in third place a long way back.
