Five-time LPGA Tour winner Hannah Green has entered the world's top 10 for the first time after overtaking Minjee Lee as Australia's top-ranked golfer.

Hannah Green has taken a giant stride towards sealing another Olympics spot, surging past Minjee Lee to become Australia's top-ranked women's golfer for the first time.

Green's commanding successful defence of her LA Championship title, her second LPGA Tour win of the year and third inside 12 months, has sent the West Australian from 18th to No.8 in the world.

Her Perth stablemate Lee dropped three positions to ninth in the new standings released in the US on Monday (Tuesday AEST).

Green's rise not only elevated the former major winner into the top 10 for the first time, a goal she's been chasing for years, but also almost certainly secures the 27-year-old a berth on Australia's Games team for Paris 2024.

Green and Lee wore the green and gold in Tokyo and now look shoo-ins to also fly the Australian flag in France in August.

The two highest-ranked women's and men's players as of June 17 will earn spots.

While Green remains wary of her talented younger compatriots, the reality is world No.82 Grace Kim — who collapsed in LA at the weekend after enjoying a four-shot halfway lead — or Gabriela Ruffels (83) or Steph Kyriacou (88) would need to win the US Open in early June plus another big event to have any hope of climbing above Green and Lee.

"The Olympics have definitely been on my mind," Green said while savouring her fifth LPGA Tour win.

"Obviously we still have six or seven weeks until the team is announced, so still a lot that can happen between now and then.

"Now that I've had two wins in the season, obviously this jumps me (into) the top 10 in the world and solidifies my spot.
