Paul Lawrie and Graeme McDowell are into the semi-finals of the World Match Play in Spain after defeating Retief Goosen and Sergio Garcia respectively.
Lawrie was in fine form as he beat Goosen 6&5 without dropping a shot, while McDowell won in sudden death.
"The wind really picked up and [being] under par, you are going to be tough to beat," said Lawrie.
The Scot now meets Nicolas Colsaerts in the last-four, and Northern Ireland's McDowell faces Rafael Cabrera-Bello.
Lawrie's good form at Finca Cortesin is also timely, as he bids for a place in Europe's Ryder Cup team for the first time since 1999 - the same year he won the Open at Carnoustie.
He currently stands fifth in the points race and has a chance to move into second spot this weekend, not least because he beat the incumbent Peter Hanson of Sweden during the group stage.
"I'm not thinking about that [the Ryder Cup], even if I win this week," said Lawrie, who has decided not to compete at next month's US Open.
The 43-year-old, who benefited from South African Goosen's sloppy start, added: "If things go well then obviously it's a step closer, but that's all it is.
"There's a lot of tournaments to be played."
McDowell was made to work harder than Lawrie for his victory, and he missed a five-foot putt for victory on the final green.
That sent the match into sudden death, where home favourite Garcia three-putted the first extra hole, the 18th, to send McDowell through to Sunday's semi-final.
"It wasn't exactly El Clasico and I feel like I dodged a bullet there," said the 2010 US Open champion.
"I kind of resigned myself to the fact that I was going home, but sometimes you have to win ugly and sometimes to win you need what just happened to me. I count myself lucky."
His opponent in the last four, Cabrera-Bello, won six of the last eight holes to recover from a three-down deficit at the turn to win 3&1 against fellow Spaniard Alvaro Quiros.
In the other quarter-final, Belgian Colsaerts beat American Brandt Snedeker 4&3 to reach the last four for the second year in a row.
