Venus and Serena Willliams are one win away from their third showdown in the Wimbledon women's final.
Younger sister Serena won both of their previous meetings in the final, in 2002 and '03.
Four-time champion Venus was first into the 2008 semifinals, beating Thailand's Tamarine Tanasugarn 6-4, 6-3. The seventh seed hasn't dropped a set all tournament headed into her final-four match against the highest remaining seed in the ladies draw. Number-5 Elena Dementieva topped fellow Russian Nadia Petrova 6-1, 6-7, 6-3 and will be playing in the Wimbledon semifinals for the first time.
Two-time champion and sixth-seeded Serena Williams picked up steam as her match wore on, disposing of Number-14 Agnieszka
Radwanska of Poland, 6-4, 6-love.
Next up for Serena is Zheng Jie. The 133rd-ranked player in the world continued her remarkable run at the All England Club with a 6-2, 5-7, 6-1 win over Nicole Vaidisova of the Czech Republic and is the first Chinese player to reach the semifinals of a Grand Slam tournament.
The 24-year-old Zheng is also the first female wild-card entrant to reach the semifinals at the All England Club and just the second at any Grand Slam.
