Overview
- Iva Jovic, the 18‑year‑old defending champion and second seed, reached the final after beating Cristina Bucsa in straight sets to try to become the tournament's first back‑to‑back winner.
- Peyton Stearns advanced to her first WTA 500 final by defeating Liudmila Samsonova in straight sets following a rain‑interrupted semifinal that tested both players' endurance.
- Top seed Marta Kostyuk was eliminated in the quarterfinals by Samsonova in a three‑set match, continuing a five‑edition Guadalajara pattern in which the top seed has not won the title.
- In doubles the top seeds Cristina Bucsa and Nicole Melichar‑Martinez will meet Peangtarn Plipuech and Momoko Kobori, a veteran pair against an unseeded team chasing their first WTA title.
- The Guadalajara Open is a WTA 500 event in its fifth edition and the singles champion will earn 500 ranking points and $185,500, a payout that could materially affect both players' rankings and late‑season momentum.
