Australia's Andrew Buckle and England's Simon Dyson shared the lead after the third round of the Indonesia Open, the duo moving three shots clear of the field on 15-under-par 201.
Taiwan's Wang Ter-chang stood alone in third place on 12 under after the 43-year-old fired a two-under-par 70 around the lush Emeralda Golf Club in the $1 million co-sanctioned European and Asian Tour event.
Ireland's David Higgins was one of four players to share fourth on 206 alongside, India's Shiv Kapur (66), Thailand's Thongchai Jaidee (72), second round leader Stephen Dodd from Wales (74).
Damien McGrane carded a level par 72 to remain four under while Peter Lawrie was well down the field on one under after a 73 left the Dulbiner on one under.
The 28-year-old Dyson is a regular visitor to the region after making headlines in his first year, when three victories in 2000 helped him win the Asian Tour order of merit.
Today, the Yorkshireman eagled the first and added four birdies against a single bogey to post a five-under 67 that moved him to the top of the standings after starting the day two shots behind Welshman Dodd in a share for second.
"I try not to watch the leaderboards to be honest," said Dyson. "I just want to keep playing as I have been doing and shooting sub-par rounds. I think if one of us shoots four or five under tomorrow, it could take it."
Buckle's charge was even more spectacular, with the 23-year-old Australian firing a flawless, seven birdie 65 to climb up from fifth place overnight. He is searching for a first victory since capturing the 2002 Queensland Open.
"I'm playing well and hitting my tee shots good as I kept the ball on the fairways," the Brisbane-born Buckle said. "I hit a couple of shots off line but managed to get out of trouble, but I'm putting well which is the main thing here."
Defending champion and last season's Asian Tour order of merit winner Thaworn Wiratchant could manage only a 71 and lay nine shots off the lead in a tie for 21st.
