Sep 17 (Field Level Media) – Top-seeded Marta Kostyuk is through to the quarterfinals of the Guadalajara Open even though she has ​yet to play a point in the Mexican ‌tournament.

The Ukrainian received a first-round bye, and she got a walkover in her scheduled second-round match on Wednesday when Taylor Townsend withdrew due to an illness.

Townsend and partner Katerina Siniakova of the ‌Czech ​Republic achieved a career Grand Slam ⁠when they won the ⁠U.S. Open women’s doubles title on Friday in New York. The pair captured the Wimbledon title in 2024, the Australian Open in 2025, and the French Open ​earlier this year.

Kostyuk is now scheduled to get her tournament underway against eighth-seeded Liudmila Samsonova of Russia, ⁠who edged Kayla Day 7-6 (4), ⁠2-6, 7-6 (5) in the last match Wednesday ​night.

In the day’s other second-round action, second-seeded Iva Jovic, the ​defending champion, topped Turkey’s Zeynep Sonmez 7-6 (5), 6-4, and ‌seventh-seeded Magdalena Frech eliminated Caroline Dolehide 6-4, 6-3.

Serbia’s Teodora Kostovic became the first player to reach the quarterfinals at Sao Paulo, ousting ninth-seeded Darja Semenistaja of ⁠Latvia 6-4, 6-1.

Kostovic, 19, will compete in a WTA Tour-level quarterfinal for the first time after saving five of the six ⁠break points ‌she faced.

The rest of the day’s action ⁠consisted of the remainder of the rain-delayed ​first ‌round. Winners included second-seeded Paula Badosa of ​Spain, third- ⁠seeded Solana Sierra of Argentina, fourth-seeded Anna Blinkova of Russia, fifth-seeded Eva Lys of Germany, seventh-seeded Kaitlin Quevedo of Spain and eighth-seeded Alina Charaeva of Armenia.

The Czech Republic’s Dominika Salkova downed sixth-seeded Jessica Bouzas Maneiro of Spain 7-5, ​6-1.
