A round of 66 from Ángel Cabrera propelled him up the leaderboard on the third morning of the Portugal Masters at the Oceânico Victoria Golf Course.
The 2007 US Open Champion shot a third-round six under par, leaving the Argentinian eight under par overall, three shots back on tournament leader Stuart Manley, who starts his round at 13.50 GMT.
A string of three birdies on the back nine, to complement a score of 34 going out, shot Cabrera up the leaderboard.
Bradley Dredge was tied for fifth overall with Cabrera after ten holes of his round, following a collection of three birdies in his first five holes.
Earlier, David Howell completed an impressive five under par 67 to take him to five under overall.
Third on The European Tour’s Order of Merit in 2006, Howell crashed all the way to 142nd last season, missing the halfway cut in six of his last seven events.
But the 33 year old Englishman lost a play-off in The Portuguese Open in April, was seventh in The Open in July and came third at The Johnnie Walker Championship in August.
After surviving the cut with nothing to spare at the Portugal Masters at the Oceanico Victoria course, Howell turned in a one under 35 this morning and then birdied three of his next four holes.
Manley, only 174th on the money list and 575th in the world, has still to record a top ten finish on The European Tour since turning professional in 2003.
But he was one ahead of Spaniard Álvaro Quirós, with Order of Merit leader Robert Karlsson three strokes back in joint fifth and Lee Westwood, third in the standings with £1.7million, tied for 18th on five under par.
