Luke Donald will take a two shot lead into the final day of the RBC Heritage after an excellent five under par 66 on Saturday.
The Englishman will be feeling hopeful of breaking his duck at Hilton Head, having twice recorded second and third-place finishes in recent years, following his exploits in the third round, which was delayed to allow some competitors to finish their second round after heavy rain forced play to be suspended on Friday.
Donald's fortunes were a little mixed on the opening nine holes in overcast and blustery conditions, but four birdies after the turn took him two shots clear of closest challenger John Huh.
"I felt really comfortable out there. I just felt like I was going to play well and obviously I did," Donald said.
"I've always liked this golf course. I'm really happy with the way I'm striking the ball, I felt like I was going to give myself a lot of chances.
"I've played extremely well today and hopefully (it will be) more of the same tomorrow. I think we're in for a very windy day tomorrow so I'll need to control the ball even better."
The 36 year old former World Number One made an early move with an eagle but he gave a shot back on four before making two birdies and as many bogeys in his next four holes.
His charge was re-ignited with birdies at the tenth and 11th, while he picked up further shots at the 14th and 17th, and was unlucky on the par four final hole when his second shot bounced inches away from the flag before rolling off the green as he settled for par.
It was nevertheless enough to keep him on eight under par overall, with Huh his nearest threat after a round of 68.
Former Major winners Charl Schwartzel and Jim Furyk, and Nicholas Thompson and Ben Martin are on five under overall after varying fortunes on Saturday, while Scotland's Russell Knox is among five players a shot further back.
English amateur Matt Fitzpatrick, who missed the cut at the Masters Tournament by a single stroke last week, was two under for the tournament after a flawless 69 which featured birdies at five and ten, while defending champion Graeme McDowell is seven shots behind Donald after his third round 72.
