Natalija Bartunkova of Czech Republic enters the Birmingham semi-finals as the world No. 69, seeking to reach her first grass-court final of the season. The Czech player has shown strong recent form with three wins in her last five matches, including a notable victory over Madison Keys in a three-set thriller and a dominant straight-sets win against Harriet Dart in the previous round. Bartunkova will face a less-experienced opponent on the surface, though she has also suffered defeats to Evgeniya Svitolina and Veronika Mboko in her recent run.

Amanda Krueger of the USA arrives at the Birmingham semi-finals ranked No. 120 in the world and riding a four-match winning streak on grass. The American has recorded consecutive straight-sets victories over Jaimee Tjen, Heather Sakatsume, and Gabby Knutson to reach this stage, demonstrating impressive consistency in her recent performances. Krueger's only setback in her last five matches came against Anja Ruzic in a closely contested three-set encounter, suggesting she remains competitive despite the ranking gap against Bartunkova.
