Julia Goerges and Elena Rybakina have faced off once before, where Goerges picked up a straight-set win in St. Petersburg last year.
Defending champion Goerges is on an eight-match winning streak at Luxembourg, but she had to come back from a set down in all three of her matches this week. She also reached the Luxembourg final in 2010, where she was runner-up to Roberta Vinci.
Rybakina is making her Luxembourg debut this week. The 20-year-old Kazakh won her first career WTA singles title earlier this season at Bucharest, defeating Patricia Maria Tig in the final.
This will be the first meeting between Jelena Ostapenko and Anna Blinkova.
Ostapenko is seeking her second final in two weeks, after finishing runner-up to Coco Gauff at Linz a week ago. That was Ostapenko's first WTA singles final showing since falling to Sloane Stephens in the Miami Open final in March 2018.
Blinkova is into her second WTA singles semifinal in one month's time. She also reached the final four at Guangzhou in September, where she lost to eventual champion Sofia Kenin. She is seeking her first-ever WTA singles final.
Coco Gauff and Caty McNally picked up the doubles title at Washington this summer. They will face Kaitlyn Christian and Alexa Guarachi in the doubles final at Luxembourg on Saturday. Guarachi is aiming for her second WTA doubles title while Christian seeks her first career title.
