Russian tennis player Liudmila Samsonova secured her place in a semifinal for the first time this year after defeating top-seeded Marta Kostyuk in the Guadalajara Open. Samsonova, 27, had reached the quarterfinals of three other events this season and last made the semifinals in June 2025 in Berlin. Kostyuk, 24, was playing her first match of the week, having received a first-round bye and a walkover in the second round following Taylor Townsend's withdrawal due to a medical emergency.
Samsonova will next face Peyton Stearns, who beat Sloane Stephens in a US quarterfinal match. Stephens failed to capitalize on three match points in the first-set tiebreaker. The other semifinal will see second-seeded Iva Jovic, the reigning champion, take on sixth-seeded Cristina Bucsa of Spain.
