Jaco Van Zyl maintained a share of the lead midway through the final round of the Turkish Airlines Open as he went in search of a first European Tour title.
The South African was two under par through eight holes of his final round but Kiradech Aphibarnrat was one shot better on the day to join him at 18 under as the duo battled it out at the top of the leaderboard.
Aphibarnrat, looking for his third win of the season after victories at the Shenzhen International and Saltire Energy Paul Lawrie Match Play, made a flying start with four consecutive birdies but a dropped shot at the seventh stalled his momentum.
Byeong-hun An was a shot behind the leaders with Race to Dubai leader Rory McIlroy and 2013 champion Victor Dubuisson a further shot back.
Conditions were perfect once again at The Montgomerie Maxx Royal and every member of the final two groups made a birdie on the par five first except for McIlroy who slipped two behind Dubuisson and Van Zyl and one behind Aphibarnrat.
Dubuisson made it two birdies out of two on the second to move out in front on his own but Aphibarnrat also picked up a shot courtesy of a lengthy putt to stay within one of the leader.
McIlroy joined the party on the third as he put a wedge in close to move to 16 under and An also picked up a stroke to sit a further shot back.
Aphibarnrat holed from eight feet to make it three birdies to start but this time Dubuisson could not follow him in and the Thai was in a share of the lead at 18 under.
McIlroy gave himself an eagle putt on the fourth but had to settle for a birdie with playing partners An and Chris Wood also picking up shots after just clearing the water.
A fourth consecutive birdie was to follow for Aphibarnrat but Dubuisson and Van Zyl followed him in for gains as the final two groups continued to prosper with McIlroy making an excellent par save from 12 feet on the fifth.
Dubuisson went through the back of the green on the fifth and had to go back to the tee, resulting in a double bogey which put Aphibarnrat out in front on his own.
He did not have the sole lead for long, though, as Van Zyl chipped in brilliantly from the back of the sixth green to get to 19 under before An got within two with a birdie ahead at the seventh.
A poor chip on the eighth led to McIlroy dropping his first shot of the day and when Aphibarnrat made a bogey back on the seventh after finding two bunkers, Van Zyl had the lead on his own.
Dubuisson also dropped a shot on the seventh to fall three shots off the lead but that gap was then reduced to two after a Van Zyl bogey on the eighth.
Shane Lowry was five under for his round at 14 under alongside Wood with Lee Slattery and Peter Uihlein a further shot back.
