Defending champion Justin Rose moved into a five-way tie for the lead as the second round of the Turkish Airlines Open got under way at Regnum Carya Golf & Spa Resort.
Paul Dunne held a slender one-shot lead overnight at the sixth Rolex Series event of the season but he dropped a shot in his first three holes to drop one off the lead, with a host of players heading in the other direction.
Dunne's playing partners Rose and Padraig Harrington moved a shot ahead of him at seven under alongside Kiradech Aphibarnrat, Li Haotong and Thorbjørn Olesen.
French pair Alexander Levy and Mike Lorenzo-Vera, Spanish duo Pablo Larrazábal and Adrian Otaegui, English trio Sam Horsfield, Tom Lewis and Danny Willett, and German Martin Kaymer were then alongside Dunne a shot off the lead.
This is a historically low-scoring event and that theme continued as the group in second at six under had swelled from three to seven before the final group had even teed off.
When they did, it was Rose and Harrington who made fast starts, putting their approaches to 12 and six feet for respectively to make it a three-way tie, with Dunne getting up and down nicely for par.
Li had birdied the par-three second and when he put his second to three feet on the next, he too was at seven under.
Aphibarnrat holed from six feet on the fourth after a birdie on the second and Olesen put his approach to the third to tap-in range to swell the group at the top of the leaderboard to six.
Our overnight leader then made his first mistake of the day, three-putting from a long way out on the par-three second to drop to six under.
Playing partners Horsfield and Kaymer both made smart birdies on the third, while Levy had gains on the first and third.
Willett made birdies on the first and fourth, Larrazábal had gains on the first, sixth and seventh, and Otaegui picked up strokes on the fourth, seventh and eighth.
Lorenzo-Vera was making the big move of the afternoon as he turned in 29 with birdies on the first, third, fourth, seventh and eighth.
Lewis holed a long putt on the eighth to go with birdies on the first, second and fourth to sit a shot ahead of eight players at five under.
