Boutier, who played 25 events a year ago, making 16 cuts, scored the biggest win of her career with rock solid par round of 72 to finish on eight-under for the tournament.

"It's massive", the 27-year-old from Aberdeen said.

"Out there today, I felt in control of my emotions and my game". But no, I'm super excited with the way I handled myself.

Kemp surged through the field with a final round of 65 and Thomas returned a 69, while Oh could only manage a 74 and overnight leader Kim Kaufman slumped to a 78 to finish four shots adrift. She was joined in second by fellow Australian Su Oh and 2019 LPGA Tour rookie Charlotte Thomas of England.

"Until then, it was just about trying to get into position for a top-three or a top-two finish".

The Vic Open at Barwon Heads in Victoria was a joint venture between the European and LPGA Tours, with the men and women playing two separate tournaments at the same time, for the same prize money, albeit with the women using different tees.

"On 15 when I made that putt, kind of really made me motivate myself and made me really more confident in my abilities to win the tournament".

"She had been putting so well; she's a good player; she's won before".

To say that Aussie Sarah Kemp had a career day is a gross understatement.

She began her round inauspiciously with a double-bogey before turning things around in dramatic fashion with nine birdies, including five in succession beginning at the fourth hole.

The CME Group Cares Challenge is a season-long charitable giving program that turns aces into donations.

Boutier made a crucial birdie on the par-4 15th hole and showed nerves of steel to claim a two-shot victory in the $1.5 million tournament at 13th Beach.

The American then holed a hard birdie from the front bunker at the short par-three seventh - known locally as "the postage stamp" after the famous par-three at Royal Troon Golf Club in Scotland - to regain control.

The LEADERS Top 10 competition awards a $100,000 bonus to the LPGA player with the most top-10 finishes through the completion of the event held immediately prior to the CME Group Tour Championship. "It's an wonderful event, we've loved it all week".

Through the first two events of the LPGA season, 21 players have top-10 finishes, led by Diamond Resorts Tournament of Champions victor Eun-Hee Ji and ISPS Handa Vic Open victor Celine Boutier.
