Australian Scott Hend moved into a one-shot lead going into the final round of the inaugural True Thailand Classic.
The 41-year-old won the Hong Kong Open in October and is holding off the challenge of the man he took that title off, Miguel Angel Jimenez, and local favourite Thongchai Jaidee.
A third-round 66 moved Hend to 15 under with a bogey on the last the only blemish on his card.
Birdies at the second and seventh saw him reach the turn in 32 but it was on the back-nine where he hit his straps, posting three birdies and an eagle before a disappointing finish.
Of the Irish, Michael Hoey endured a disappointing day which has seen him drop out of contention, his round of 73 included three bogeys and left him on one-over. Damien McGrane is one shot further back after he claimed a 74.
Meanwhile, Hend commented: "It was a good round and puts me in a good position. I played very solidly and putted quite well. I only made one mistake so it was pretty good."
He added: "This is where you want to be, in the last group on a Sunday. I'll be playing with Thongchai again and Miguel so it'll be a good little test tomorrow.
"I'm very lucky and privileged to be playing golf for a living and being in contention on Sundays is what we're all trying to do."
Jimenez had been battling a heavy cold on Friday but still managed to fire a 66 and he followed that up with a 69.
Birdies on two, 10 and 17 lit up a steady round for the 51-year-old Spaniard who will be looking to break his own record as the Tour's oldest winner on Sunday.
"I'm playing well and hitting it well," he said. "I missed a few putts I'm creating lots of chances.
"I've played three rounds with Kiradech and tomorrow I'll play with Thongchai - it's good for the tournament to have the Thai guys in contention."
Jaidee also had a bogey-free round as five birdies saw him sign for a 67 while countryman Kiradech Aphibarnrat was a further shot back.
Three Australians were then sat on 11 under as Andrew Dodt, Richard Green and Wade Ormsby shared a tie for fifth with Sweden's Alex Noren.
