Britain's Emma Raducanu produced a dominant display against Linda Noskova to set up a last-eight meeting with Iga Swiatek at the Stuttgart Open.
Raducanu needed 81 minutes to claim a straightforward 6-0 7-5 victory.
The 21-year-old will face world number one and defending champion Swiatek in the quarter-finals after the Pole defeated Elise Mertens 6-3 6-4.
Swiatek, who is on a nine-match unbeaten run in Stuttgart, has a 2-0 win record against Raducanu.
"It's a match where I have nothing to lose, I can just swing and enjoy it," the Briton said.
"We played here two years ago in the quarters so it's exactly the same.
