US Open champion and top seed Kim Clijsters cruised into the Luxembourg Open final with a 6-3 6-1 win over Nathalie Dechy of France.
After disposing of the French fourth seed, Belgium's US Open champion now faces Anna-Lena Groenefeld.
The unseeded German reached her second final in two weeks with a 6-4 5-7 6-4 upset win against Dinara Safina.
The 20-year-old showed her grit to move past Russian seventh seed Safina after falling a break behind in every set.
Groenefeld, who started the year ranked 75, is up to a career-high 23 after reaching last week's final in Beijing.
Looking ahead to the final she said: "I'm going to have to play aggressively against Kim because she always gets the ball back and makes you play one more shot.
"She moves so well so I'm going to have to be ready for the next shot."
Clijsters, who has made a successful comeback from injury this season, will be chasing her 29th tour title on Sunday and eighth this year.
However, she felt there was room for improvement on her display against Dechy.
"I was always trying to keep pressure on her but felt a little tight and I was making a few mistakes.
"My footwork and movement was not as it should be and I made a few unforced errors."
Groenefeld ran Clijsters close in the first set when they met this year at Stanford when the Belgian won 6-4 6-0.
"I know after the match in Stanford that I have to be ready," the Belgian added.
