Min Woo Lee plans on celebrating his watershed Houston Open win with the best golfer in the family.

As well as rising above Adam Scott to become Australia's new No.1 ahead of another Masters tilt, Lee completed a rare double with his epic victory over Scottie Scheffler on Monday.

The 26-year-old Perth ace and sister Minjee are only the third siblings to notch wins on the PGA Tour and LPGA Tour respectively.

The other two are Cathy and Billy Kratzert and Jackie and Jim Gallagher Jr, all American.

The Lees were already the only brother-sister act to have both won the US Junior Amateur title and last year represented Australia at the Paris Olympics in another special family affair.

For all his talent, Min Woo has often conceded he's not even the best player in the family having long lived in the shadows of 28-year-old dual major champion Minjee.

But he's edging closer, on rankings at least.

While Min Woo has surged up to No.22 in the world in the men's standings, Minjee has fallen from second to 18th in the women's having gone winless since 2023.

Little wonder Minjee was the first family member to congratulate him on a FaceTime call after the three-time European winner stared down world No.1 Scheffler to secure his maiden PGA Tour title.

"I called my family, and my mum was crying as usual, dad was very happy," Min Woo said.

"My sister was the first one to pick up. I talked to her yesterday about having dinner tomorrow. She's in Vegas and I live there and she's playing an LPGA tournament there.

"So it will be very cool to see her. I haven't seen her in a little bit, so it's very cool to have a sister that's really good at golf, and she's going to win soon, too."

Looming as a serious Masters contender when the season's first major gets under way on April 10, having tied the back-nine final-round scoring record on debut in 2022, Min Woo still reckons Minjee might have the wood on him in a money game.

"If we play from the same tees, I'll smoke her because I hit it very far," he said.

"But if she played from her tees and I played from mine, it would be pretty close.

"She's got the long putter in now so she can putt and she's doing really good over the last couple months putting.

"Over the long run I think she might beat me. She's a robot. She probably would have hit 19 fairways out of 18 fairways today because she's a robot.

"She's very straightforward and she controls the ball so well. Over time she'll probably win, but if there was a little short sprint I might win."
