Thorbjorn Olesen has one hand on the Turkish Open title after extending his lead to seven shots going into Sunday's final round.
The Dane had a six-shot advantage at the halfway mark as a result of setting a new course record with a sublime nine-under 62 at Regnum Carya Golf & Spa Resort on Friday.
Olesen looks set to claim his first European Tour title of the year and ensure he has won at least once for three consecutive seasons following a three-under third round of 68 in Antalya.
The 26-year-old's lead was cut to four shots at one stage on Saturday, but he picked up three birdies in a row on the back nine and is firmly in command on 18 under despite a second bogey of the day at the last.
"I've never had a seven-shot lead," said Olesen, back on song after making just three of his last 12 cuts. "I felt a bit nervous when I went out today also because I've never been that many shots clear.
"It's a bit of a weird feeling but I know it's not easy and there's a bunch of guys there and it's possible to shoot a really low one out here. I'll stay aggressive tomorrow and keep plugging away.
"This is the Final Series and it's a massive event and obviously it would be great to win it. There's still 18 holes left and I really have to stay concentrated out there and stay in my own little zone."
Matteo Manassero, David Horsey, Li Haotong, David Lipsky and Bernd Wiesberger share second place on 11 under.
Lipsky went out in 30 after making three consecutive birdies and another gain at the ninth, but failed to build on that blistering start after the turn and signed for 66.
Wiesberger matched the American's round, while Manassero, Horsey and Li went round in 68. George Coetzee and Thongchai Jaidee are eight shots adrift of runaway leader Olesen in a share of third.
