(CNN) -- Tiger Woods remains in contention at the Turkish Airlines Open but it is a little-known Frenchman who could make a name for himself come Sunday evening.
Victor Dubuisson was tied for the lead after Friday's second round but now finds himself five shots clear of the field following a superb score of 63 on Saturday.
The 23-year-old who hails from Cannes put together a flawless, nine-birdie round at the Montgomerie Maxx Royal course in Antalya to finish on 21-under par with just Sunday's final round to play.
"I'm very tired now, so I think I will sleep easy tonight. But it will be very stressed I think," said Dubuisson, who has yet to win on the European Tour.
"I'll try not to think about it because if I think about it, I will put too much pressure on myself. But I know tomorrow Ian, Tiger and Henrik, they will shoot very low scores, so I have to keep the same strategy.
"I know I have a five-shot lead, but with all these great players, tomorrow it will be a very tough day."
Dubuisson's 54-hole total of 195 is five shots better than joint-overnight leader Ian Poulter who continued his consistent showing with a four-under par round of 68 leaving the Englishman on 16-under par.
Sweden's Henrik Stenson and South Africa's Justin Walters, who also started the day tied for the lead, both slipped a little further down the leaderboard after rounds of 69 and 70 respectively.
Walters two-under round leaves him in seventh on 14-under par, while Stenson finds himself in a four-way tie for third at 15-under with Spain's Alejandro Canizares, France's Raphael Jacquelin -- who shot a course record 62 -- and a certain Tiger Woods.
The 14-time major champion started his round where he left off on Friday, bagging a birdie at the first with two more (at three and eight) coming on the opening nine.
Woods moved to 15-under par with a birdie at the par-five 11th but endured an erratic end to his round picking up three bogeys and three birdies in the remaining seven holes.
Afterwards, the 37-year-old revealed that he had injured his arm during the round but doesn't expect it to curtail his involvement in the tournament.
"My arm is a little tender. I smoked it on something. I don't know what I hit but I hit something hard," Woods said.
"I just dealt with it, and you know, just play through it. I won't need any treatment as anti-inflams will be good."
Woods is enjoying his best season since 2009, but his game will need to improve on Sunday if he is to claim his sixth title of 2013.
"To birdie the last hole was a nice way to end, considering I struggled all day with swing. I was getting away with it on the front nine, but I wasn't really playing well and it caught up with me on the back nine."
U.S. Open champion Justin Rose is tied for eighth place with Welshman Jamie Donaldson. The Englishman shot a five-under par 67 to leave him on 13-under, eight shots behind Dubuisson.
