Robyn Choi is just three shots off the pace after the opening round of the LPGA Tour's Maybank Classic.
The 28-year-old Australian, currently 68th in the live rankings, remains a chance of reaching the season-ending Tour Championship, an $US11 million ($A16 million) showpiece featuring only the top 60 in the year-long points race.
Choi, who started the day in 74th, drained birdies on the fourth, 10th, 13th, 14th and 18th holes for a blemish-free five-under-par 67 at the Kuala Lumpur Golf and Country Club on Thursday.
