Swedish Ryder Cup star Henrik Stenson will play defending champion Geoff Ogilvy in the 36-hole final of the WGC Match Play in Arizona on Sunday.
Stenson beat South Africa's Trevor Immelman 3&2, while Australia's Ogilvy also downed American Chad Campbell 3&2.
Stenson took the lead at the first and was never headed, alternating between two and three up from the fourth hole.
US Open champion Ogilvy was one down after seven but took the decisive lead on the 9th before winning on the 16th.
Immelman and Campbell will fight it out over 18 holes for third place on Sunday.
"I'm knackered now, playing two rounds today. It was nice not to have to go all the way to the end in this one," said Stenson, 30, who held off Ernie Els and Tiger Woods to clinch his fifth European Tour title at this month's Dubai Desert Classic.
Ogilvy, who beat PGA Tour veteran Davis Love III 3&2 in last year's 36-hole final at La Costa in California, has now won 11 consecutive matches at the event.
He said: "It's been good so far. I don't know what I'm doing but I'm making the right putts at the right times. Henrik's obviously playing well so it should be fun."
Earlier on Saturday, Stenson beat Tiger Woods' conqueror Nick O'Hern one up, while Ogilvy downed Wentworth World Match Play champion Paul Casey 5&4.
In the other quarter-finals, Immelman beat England's Justin Rose 5&4 and Campbell knocked out Canada's Stephen Ames by one hole.
