Lee, 25 and ranked No. 5 in the world, will rise even closer to world No. 1 after her first win of the 2022 season.

The superstar from Royal Fremantle did not have her best day but finished with a flourish, hitting a pure wedge from 100 metres at the 18th hole and holing the putt from inside two metres for a birdie and a two-shot win.

She shot 67-63-69-70 to post 19 under par, but it was a struggle on the final day, and American Lexi Thompson had a chance to force a playoff as they came up the last, just a shot apart.

Once Thompson missed her birdie putt from six metres, Lee had two putts for the win, and only needed one.

“I putted really well, so I’ve got to take the positives,” she said. “I feel really good and even though I didn’t strike it that well today, I’m really, really happy.”

Lee watched a lot of putts slide by the hole, but contained her frustration. “A lot of them lipped out but at the end of the day, I still got the job done, so I’m happy.”
