Spain's Garbine Muguruza thrashed unseeded Slovakian Magdalena Rybarikova to set up a Wimbledon final against either Britain's Johanna Konta or five-time champion Venus Williams of the US.
Muguruza, 23, won 6-1 6-1 in just 64 minutes on Centre Court to advance to her second Wimbledon final.
The 2016 French Open champion will try to win her second major title in Saturday's final.
Konta hopes to become Britain's first women's singles finalist since 1977.
The Briton, seeded sixth, is up against a Wimbledon legend in Williams, seeking her first Grand Slam title for nine years at the age of 37.
