## 🎯 Key Points

- Kostyuk advanced to the quarterfinals of the WTA 500 in Guadalajara without a match due to Taylor Townsend's withdrawal.
- Townsend withdrew from the tournament due to a sudden illness before the start of the match.
- Kostyuk's quarterfinal opponent will be determined after the match between Kayla Day and Lyudmila Samsonova.

Ukraine's No. 2, Marta Kostyuk, secured her place in the quarterfinals of the WTA 500 tournament in Guadalajara, Mexico, before the scheduled match. Her second-round contest never took place: her first-round opponent, American Taylor Townsend, was forced to withdraw from the competition due to a sudden illness. This is reported by Sport RBC.UA, citing the official website of the Women's Tennis Association.

### How the match was cancelled

Kostyuk entered the tournament as the top seed, which automatically granted her a bye into the round of 16. In the first official round, she was set to face American Taylor Townsend (WTA 98), who had previously topped the world rankings in doubles. However, the match was cancelled before it began: the American was unable to take the court due to a deterioration in her condition, and the Ukrainian advanced to the quarterfinal stage without expending any effort.

### Position in the draw and the next step

Kostyuk is now awaiting the conclusion of the second round to learn the name of her future opponent. Her opponent will be determined by the match between American Kayla Day (WTA 123) and Russian Lyudmila Samsonova, competing under a "neutral" status (WTA 50). Thus, Kostyuk's quarterfinal match will be played only after this second-round pairing is completed.

### Conflicting data

Official WTA materials and Sport RBC.UA reports emphasize that Kostyuk's quarterfinal opponent has not yet been determined and will only be known after the Day–Samsonova match. At the same time, a number of sports outlets have already published previews of the Kostyuk–Samsonova pairing, effectively treating the Russian as her opponent. The discrepancy in versions is explained by the fact that the previews are based on a prediction of the second-round outcome, whereas the official draw lists only two possible candidates. Until the Day–Samsonova match is finished, neither of them can be named the Ukrainian's opponent with full certainty.

### Tournament context

The Guadalajara tournament belongs to the WTA 500 category and is played on a hard court. For Kostyuk, who occupies a top position in the world rankings, advancing to the quarterfinals without playing is a convenient scenario before the decisive stages of the competition, allowing her to conserve energy ahead of potentially demanding matches. The Ukrainian's further trajectory in Guadalajara will depend on the outcome of the second-round pairing and the form she demonstrates in the quarterfinal.
