Carl Suneson of Spain and Dutchman Maarten Lafeber share the lead after three rounds of the Beazer Homes Challenge Tour Championship at Bowood Golf and County Club.
They are on 10-under-par 206, two ahead of Marc Pendaries of France and three clear of another Frenchman, Benoit Teilleria and two Englishman, Carl Watts and Lee James.
On a sunny, hot day, Lafeber followed up his course record 63 on Friday with 66 to set the clubhouse target which Suneson matched thanks to an eight-foot birdie on the final green.
"I didn't play quite as well as when I shot the record," said Lafeber. "I drove into a couple of fairway bunkers but I recovered well so there wasn't much damage done."
Suneson carded three birdies and a bogey in his 70 and declared: "I played well but I didn't hole the putts. I left the ball too far from the holes and the greens are slow. But there is all to play for tomorrow."
Pendaries had seven birdies in his 67 while Teilleria kept himself in the hunt with 70 to be joined by Watts, also with 70, while James, a Challenge Tour regular until two years ago, carded two birdies in the last four holes for a 68.
England's Justin Rose got to within a shot of the lead after 15 holes but successive bogeys at 16 and 17 brought him home in 70 for 211, five under par, and five shots behind the leaders.
"It was annoying to finish like that," he said. "I was looking to pick up a shot not drop two."
