Hannah Green's red hot run of form continued in Thailand today as she surges toward a top-10 world ranking for the first time in her career.

The Perth superstar opened with a six-under par 66 at the Honda LPGA Thailand tournament at Siam Country Club near Pattaya City, putting her within two shots of the lead in a tie for fifth place.

She made six birdies and not a single bogey, chipping up close at the par-five 18th hole and rolling in the putt from two metres for an exclamation mark on a good day in the heat.

Green finished runner-up in Singapore last weekend and was third in the LA Open at her previous start, and her world ranking has climbed to No. 13.

On current form she has a chance to overtake another Western Australian, world No. 10 Minjee Lee, as the top-ranked Australian soon.

Green has not won since 2019 when she became just the third Australian woman to win a major, but she has hit the ground running in 2021.

Lee opened with a one-under 71 and Victorian Su Oh also had a good day, carding an even-par 72, while Katherine Kirk was one over par for the day.

Two Thai players -- major-winner Patty Tavatanakit and Atthaya Thitikul are the leaders after recording opening 64s.
