The four quarterfinals at the Birmingham grass court tournament were cancelled for the day due to rain on Friday.
Two Czech players are scheduled to compete, with eighth-seeded Marie Bouzkova facing Coco Vandeweghe of the United States, and Tereza Martincova taking on fourth-seeded Daria Kasatkina of Russia.
Second-seeded Ons Jabeur of Tunisia faces Anastasia Potapova of Russia, and third-seeded Donna Vekic of Croatia is up against local favorite Heather Watson.
Vandeweghe, a former top 10 player, reached two Grand Slam semifinals in 2017 and twice has been a quarterfinalist at Wimbledon.
She earned her first tour-level, main-draw victory in nearly two years on Monday by beating Kristyna Pliskova in straight sets.
