(CNN) -- Retief Goosen will take a one-shot lead into the final round of the Portugal Masters after the two-time major winner shot his second successive round of eight-under-par 64 in Vilamoura.
Retief Goosen has shrugged off his poor Presidents Cup form at the Portugal Masters.
The South African, seeking his first win on the European Tour since January 2007, came from three shots behind halfway leader Francesco Molinari to take the 54-hole pole position on Saturday.
The 40-year-old, who did not win a match for the International team in last week's Presidents Cup defeat by the United States but has claimed three titles in Asia, Africa and the U.S. in the past 12 months, started with a birdie and then pitched in for eagle at the second hole.
He fired three birdies in a row from the 10th and then chipped in at 15 to bounce back from a bogey on the previous hole, and picked up another shot at 17 to become the first man to reach 20-under after three rounds in Europe this season.
"Last week was very disappointing for me, but the last two days have obviously been great," said Goosen, twice a winner of both the U.S. Open and the European Tour's Order of Merit money list.
Molinari, who started the tournament with a sensational 63, followed up his second-round 66 with a 68 featuring six birdies and two bogeys at the Oceanico Victoria Golf Course.
The Italian finished the day two shots ahead of third-placed Englishman Lee Westwood, who finished with two birdies to card 66.
The Ryder Cup star can overtake Rory McIlroy at the top of the Race To Dubai standings with a second-place finish on Sunday, with his young Northern Irish rival back in a tie for 53rd after a third-round 71.
Spain's Pablo Martin was fourth on 16-under after a 68, one shot ahead of Englishmen Oliver Wilson (64) and Gareth Maybin (65), Ireland's Peter Lawrie (65) and South Africa's Charl Schwartzel.
Goosen's playing partner Padraig Harrington was in a tie for ninth on 14-under, as he followed up his second-round 62 with a relatively disappointing two-birdie 71.
