Thorbjorn Olesen set a new course record at the Regnum Carya Golf & Spa Resort on Friday to open up a commanding six-shot lead in the Turkish Open.
The Dane, who had begun strongly with a 65 in round one on Thursday, turned on the style a day later, making a birdie at the first and adding three more to reach the turn in 30.
Olesen bogeyed the par-four 11th but that proved to be his only dropped shot. Indeed, it may have served to inspire a blistering finish, as he made four birdies and an eagle three, secured by a brilliant 35-foot putt, in the last six holes.
Having earlier holed a monster 30-footer for birdie on the eighth, he also conjured some magic on 17, setting up a birdie putt with a brilliant approach shot after finding the trees off the tee.
Coming in the first event of the Race to Dubai Final Series, it was a timely return to form for a player who had made just four of his previous 13 cuts.
The 26-year-old will go into Saturday's third round at 15 under, six strokes ahead of Thongchai Jaidee and Adrian Otaegui, who are tied second at nine under.
"Yesterday was a great putting display, and today I played better and still putted great, so it's been a couple of good days," said the overnight leader.
"I feel like I've been up in contention in a lot of big events so I feel pretty comfortable.
"There are still 36 holes to go, so that's a lot of golf to be played but I have to keep being aggressive out there, keep going after some of the pins and try to make birdies. That's the only way I can win."
Spaniard Otaegui broke the course record with an eight-under 63, only to relinquish the low mark when Olesen romped down stretch.
Swede Joakim Lagergren also went low, shooting a seven-under 64 to earn a share of fourth at eight under, alongside David Horsey of England, Italian Matteo Manassero and China's Li Haotong.
It was a day to forget for overnight leader George Coetzee, the South African posting a two-over 73 to drop into a six-way tie for 13th, 10 shots back from Olesen.
