Rebecca Masarova, ranked 132 in the world, represents Switzerland in the Birmingham final on grass. The left-hander has shown mixed form recently, with three wins against Leylah Fernandez, Olga Selekhmeteva, and Jil Teichmann offset by losses to Maria Lourdes Carle and Jessica Pegula. This is Masarova's first career meeting with Naef, and she will aim to capture her first grass-court title in what is a significant opportunity for the Swiss player.

Cristina Naef, ranked 216 and also competing for Switzerland, has struggled for consistency in recent matches with three losses to Stefanie Kraus, Anna Blinkova, and Ekaterina Kudermetova, plus one win over Yaroslava Bartashevich. The final marks a career-high appearance for Naef at a WTA 250 event on grass. With no previous head-to-head record against Masarova, Naef will look to upset her higher-ranked compatriot in what represents her best tournament performance to date.
