South Africa's Retief Goosen fired a second straight 64 to take a one-shot lead into the final day of the Portugal Masters at Vilamoura.
The two-time US Open champion, who has not won on the European Tour since 2007, carded an eagle two and seven birdies to reach 20 under par.
Italian Francesco Molinari is second, two ahead of England's Lee Westwood.
Overnight leader Padraig Harrington is six off the lead after a 71, while Justin Rose is on 11 under.
In the battle to become European Tour number one, now named The Race To Dubai, Westwood would overtake young Northern Irishman Rory McIlroy by finishing second on Sunday.
However, Westwood, who fired seven birdies including two in a row at the end of the round, said: "As Seve (Ballesteros) used to say 'second is no good.'
"Now my caddie Billy (Foster), who used to caddie for Seve, is saying that to me. Going top (of the money list) would be good but I want to do it by winning."
It's been a disappointing time on the European Tour without a win but for the last year I've been a little bit more consistent
McIlroy struggled with the putter again in round three and is 14 shots off the pace.
Goosen, now 40, seeking his 15th European title, carded a second successive 64 to edge ahead of Molinari, whom he had previously trailed by three.
The South African pitched in for his eagle at the second and then rolled in five birdies on the inward nine.
His round was the first 20-under 54-hole aggregate in a European event this year.
He explained how some poor form at last week's Presidents Cup, in which he failed to win a match, allowed him time to iron out some problems with his game.
"Last week was very disappointing playing and putting-wise," he said.
"I had Saturday afternoon off last week and spent three hours on the range improving the swing, and the putting has come right this week too.
"It's been a disappointing time on the European Tour without a win but for the last year I've been a little bit more consistent. I'm looking for one more good round to see if we can pull it off."
