Sattaya Supupramai remained in control on the second day of the King’s Cup presented by PTT Group.
The World Number 1048 came into day two with a two-shot lead after producing a seven-under-par 63 at Phoenix Gold Golf Club on Thursday.
And he still had that two-stroke advantage when he began his second round at 12:50, with none of the early starters able to close the gap.
Supupramai continued to impress on Friday, making gains at the 11th - his second hole - and 14th to cover the front nine in 33 and reach nine under.
Joachim B Hansen was two shots back in second place at the turn after getting his second round off to a fantastic start.
The Dane opened with three straight birdies from the tenth before adding another at the 14th to move to seven under.
Australian Terry Pilkadaris was another shot back on six under after notching two birdies in his first 12 holes.
Earlier in the day, Lin Wen-tang and Sutijet Kooratanapisan set the clubhouse target on five under.
