Scotland's Simon Yates will take a two-shot lead into the final round of the UBS Hong Kong Open tomorrow.
Yates carded a superb 61 at Fanling Golf Club for an 11-under-par total of 199, two clear of tournament favourite Colin Montgomerie, last year's runner-up James Kingston, and Swede Martin Erlandsson.
The 35-year-old Glasgow-born professional, who has been based in Asia for the last decade, carded nine birdies in a flawless round to establish a new course record on the composite layout.
And it could have been even better after his approach to the eighth, where a car is on offer for the first hole-in-one, hit the pin and rolled five feet away.
"This season has been slow as I've not concentrated on my golf," said Yates, who represented Scotland at downhill skiing in his youth.
He added: "I went to warm up in Vietnam a few weeks ago to prepare for the big events and said to myself I needed to start playing some good golf. I've been playing all right up to the third or last round and not playing great after that. Every time I put on this red shirt I'm two or three over and I was thinking I was going to dump it after today. Seems like my luck has changed."
Montgomerie carded a second consecutive 66 but was left to rue three dropped shots which cost him the outright lead.
The 42-year-old Volvo European Order of Merit winner said: "I had three fliers from the rough, on the ninth, 15th and 16th, and dropped three strokes but the rest was okay. I've got myself into position on Saturday night and that's always the goal at the start of the week.
"I just have to shoot something quite low tomorrow. I said 14-under would win and I'm sticking with that. I need a 65 tomorrow and I'm quite capable of doing that."
Ireland's Damien McGrane is a shot behind Montgomerie on eight-under after a 63 which featured birdies at four of his last five holes.
"I hit a lot of good shots close and every time I hit a good shot it ended up close and I converted the putt," McGrane said.
"There are a lot of birdie chances out there and all the top players are certainly going to move forward, and if I can do the same tomorrow as I did today then I will be right in there."
Meanwhile, Gary Murphy carded a 67 to move to two-under, while Peter Lawrie returned on 71 to two-over.
On a crowded leaderboard, Holland's Maarten Lafeber and England's Oliver Wilson were among a large group on seven-under.
Wilson, who lost a play-off to Paul Casey in the Volvo China Open on Sunday after leading by one with two to play, carded his second consecutive 64 to continue his amazing recovery from a first round 75.
Lafeber went one better with a 63 after six birdies in his first seven holes took him to the turn in 28. A first sub-60 round on the European Tour was on the cards - the par at Fanling is 70 - but the 30-year-old hit his approach to the 10th into water and also bogeyed the 14th.
"If ever there was a day to think about a 59 then this was it," admitted Lafeber, who won the Dutch Open in 2003 to become the first home player since 1947. "I don't think I've played much better tee to green all year. I was six-under after nine holes, and that was nine pretty difficult holes.
"I think the back nine is a little bit more forgiving but I made a stupid mistake on the 10th, hitting my sand iron fat and short into the water, and that knocked me a bit. I gave myself a chance on nearly every hole but I just didn't make the putts."
Meanwhile, Lafeber's countryman, Robert-Jan Derksen, had won a 1kg gold bar, worth $15,000 dollars, for a hole-in-one on the 144-yard 12th hole.
